What Is Brass Composition and Properties

Brass is an alloy made primarily of copper and zinc. The proportions of the copper and zinc are varied to yield many different kinds of brass. Basic modern brass is 67% copper and 33% zinc. However, the amount of copper may range from 55% to 95% by weight, with the amount of zinc varying from 5% to 40%. Lead is commonly  added to brass at a concentration of around 2%. The lead addition improves the machinability of brass. However, significant lead leaching often occurs, even in brass that contains a relatively low overall concentration of lead. Uses of brass include musical instruments, firearm cartridge casing, radiators, architectural trim, pipes and tubing, screws, and decorative items. Brass Properties Brass often has a bright gold appearance, however, it can also be reddish-gold  or silvery-white. A higher percentage of copper yields a rosy tone, while more zinc makes the alloy appear silver.Brass has higher malleability than either bronze or zinc.Brass has desirable acoustic properties appropriate for use in musical instruments.The metal exhibits low friction.Brass is a soft metal that may be used in cases when a  low chance of sparking is necessary.The alloy has a relatively low melting point.Its a good conductor of heat.Brass resists corrosion, including galvanic corrosion from saltwater.Brass is easy to cast.Brass is not ferromagnetic. Among other things, this makes it easier to separate from other metals for recycling. Brass vs. Bronze Brass and bronze may appear similar, yet they are two distinct alloys. Heres a comparison between them: Brass Bronze Composition Alloy of copper and zinc. Commonly contains lead. May include iron, manganese, aluminum, silicon, or other elements. Alloy of copper, usually with tin, but sometimes other elements, including manganese, phosphorus, silicon, and aluminum. Color Golden yellow, reddish gold, or silver. Usually reddish brown and not as bright as brass. Properties More malleable than copper or zinc. Not as hard as steel. Corrosion resistant. Exposure to ammonia may produce stress cracking. Low melting point. Better conductor of heat and electricity than many steels. Corrosion resistant. Brittle, hard, resists fatigue. Usually a slightly higher melting point than brass. Uses Musical instruments, plumbing, decoration, low-friction applications (e.g., valves, locks), tools and fittings used around explosives. Bronze sculpture, bells and cymbals, mirrors and reflectors, ship fittings, submerged parts, springs, electrical connectors. History Brass dates back to around 500 B.C.E. Bronze is an older alloy, dating back to about 3500 B.C.E. Identifying Brass Composition by Name Common names for brass alloys may be misleading, so the Unified Numbering System for metals and alloys is the best way to know the composition of the metal and predict its applications. The letter C indicates brass is a copper alloy. The letter is followed by five digits. Wrought brasses — which are suitable for mechanical forming — begin with 1 through 7. Cast brasses, which may be formed from molded molten metal, are indicated using an 8 or 9.

Why The Crucible Remains Important Today Essay - 976 Words

Why ‘The Crucible’ Remains Important Today For a story of any kind to have any relevance or meaning some 50 years after being written and indeed almost 400 years after it was set, it needs to contain themes and ideas that have been uniformly felt and experienced by people from all walks of life as well as continuing to speak to and have meaning to new and changed generations of people. Years after being written, Arthur Miller’s ‘The Crucible’, still successfully speaks to numerous generations of people, that although live in different countries, under different governments and belong to different peer groups, experience the same issues that the characters of ‘The Crucible’ experienced as well as the same issues that were experienced by†¦show more content†¦Their only other option is to follow their beliefs and morals by refusing to lie which quite possibly could result in death by hanging. This kind of pressure has plagued cultures everywhere for almost all of time and it begs the que stion: ‘Is a person bad if they do not live by the rules of the Church, their government or their social group and if so should they be prosecuted for their own interpretations of these rules’? People under-stand now more than ever, that if they decide to deviate from what is considered to be socially normal, they will be labeled and in many cases cast out or excommunicated from the society from which they originate. ‘The Crucible’ not only addresses the issue of conformity, it attacks the poor balance of power that surrounds us everyday. Miller demonstrates how much power a sole in-dividual can have when the decisions made by that person effect a whole community. During the Witchcraft Trials in Salem, religion was, much more than now the answer to the unknown and the unexplained. As a result, the Church and the people in its service were people of prominence and power. They were the only people who could successfully interpret the Church’s doctrine, often to their own benefit, without being accused of a wrong doing and what could be more powerful than this in a theocratic society like Salem? This corrupt hierarchy meant that nobody could question a priest or minister because doing so would beShow MoreRelatedEssay about Why the Crucible Remains Important Today1015 Words   |  5 PagesWhy ‘The Crucible Remains Important Today For a story of any kind to have any relevance or meaning some 50 years after being written and indeed almost 400 years after it was set, it needs to contain themes and ideas that have been uniformly felt and experienced by people from all walks of life as well as continuing to speak to and have meaning to new and changed generations of people.

Analysis Of Michael Ogbeidi s The First Republic

Michael Ogbeidi recounts that ‘the First Republic under the leadership of Sir Abubakar Tafawa Balewa, the Prime Minister, and Nnamdi Azikwe, the President, was marked by widespread grand corruption’. Ogbeidi maintains that ‘government officials looted public funds with impunity. Federal Representative and Ministers flaunted their wealth with reckless abandon†¦ Politically, the thinking of the First Republic Nigerian leadership class was based on politics for material gain; making money and living well’.

For Effeh, ‘it follows that the ideals for economic emancipation- the supposed inspiration behind the quest for independence- has become the subject of escapist antics, grandiloquent rhetoric, and/or outright buffoonery’. However, amidst all this rhetoric, people seemed to overlook the complexities within the system that nourished and sustained the unwavering wind of grand corruption and rather greater emphasis was laid on its manifestations and consequences as will be depicted in the speeches of succeeding military regimes as will be analysed in the next section ( section 2.4). 2.4 Grand Corruption (The Nigerian Military Connection) Research indicates that the military played very prominent roles in sustaining grand corruption in Nigeria as ‘corruption, already bourgeoning under the early politicians, became entrenched under the military rule’. Military coups forcefully circumvent democratic institutions and because of their illegitimacy, it can be argued that the track records of the military portend that they had little regard over the well-being and welfare of the populace and as such pursued no mandate of accountability and transparency towards the people. The military rulers were able to perpetrate their

Condoms a New Diploma Critical Analysis free essay sample

He provides his definition of gender and sex roles. He claims that sex has consequences by using Magic Johnson as a specific example and implies that some people will not say this. He claims that his opposition opposes teaching abstinence by using examples from the City Board of Education In New York and Jacksonville, Florida. He also claims that there is a culture war on condom distribution and that It is a part of the current situation. Lumbago provides statistics and analogy intended to show that condoms are not effective by lacing a comparison between condoms and airplanes.He wraps up this essay by using another reduction ad absurdum on sex education. The Authors purpose Is to convince the reader that condom distribution In schools can lead to contracting Sexually Transmitted Disease or Studs and encourage promiscuity. He wants the reader to understand that distribution of free condoms in public schools is ridiculous and misguided. We will write a custom essay sample on Condoms a New Diploma Critical Analysis or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Lumbago uses reduction ad absurdum by saying that kids are going to have sex and that we cannot stop them. He also uses other examples such as kids are going to make and why not provide them with cigarettes and many more examples from guns and safe sex centers.Here Lumbago uses this rhetorical tool to prove to the reader that by providing a free condom to the teenager can lead them to doing other things that may harm them since they cannot be stopped. He continues on by going past giving away free condoms and installing Safe sex centers. Lumbago proves a point that by stating that by giving away condoms they compromise their standards making his point hard to argue against therefore his tool of using reduction ad absurdum proves to be effective to the argument. Lumbago uses another specific example such as Magic Johnson, a basketball athlete for the Los Angels Lasers. He uses an adult celebrity to prove a point that the same stakes are involved as an adult who arent aware to the dangers of having condom-protected sex. Still using the same tool of reduction ad absurdum, Lumbago identifies that there are many people out there that will have sex with others that may have contracted AIDS with or without using a condom and that many people believe that condoms can help them prevent from spreading Studs.This tool is proven to be effective since it Is hard to argue that adult human beings will have sex with or without the knowledge that their partner has aids as to teenagers having sex with or without the knowledge of a condom. 1 OFF percent and compares it to the safety of an airplane. The statistic used for the condom proves to be incorrect since the failure rate of a condom is very low ranging from 2 to 4 percent if used correctly.The compariso n used between the lives of passengers in a plane to the failure of a condom used by any being is far off since modems sold as a product are proven to reduce the chances of pregnancies and sometimes Studs. This tool is ineffective since the statistics of the condom failure is questionable and the analogy of an airplane since products are made to be safe and would be discontinued if it has failed its standards. Lumbago creates an offensive persona throughout the essay as he uses examples such as Magic Johnson or Johnnie and Susie as a way to taunt the opposition by refuting the argument many times throughout the essay.Since we cannot attack a deduction ad absurdum by pointing out its ridiculous nature it proves a point within itself and as Lumbago speaks about how condom distribution can compromise our standards, he proves a point that the opposition is willing to accept that teenagers will have sex no matter what and it is not helping in the prevention of Studs. Lumbagos persona of being the offensive and taunting the opposition proves to be effective since giving a teenager a condom can encourage them to have sex. In conclusion, Lumbagos use of Reduction ad absurdum and the many tool s to reverent schools from distributing condoms can lead to promiscuity.

In the body paragraphs, discuss the history and all notions that define the essence of Americanism. Remember not only define, but show how Americanism shapes the identities of Americans.   The last part of your essay, a conclusion, should summarize the main points and include your final thoughts on why Americanism is so important for the citizens.
