Write the composition of following alloys:
a) Brass b) Bronze c) Solder d) Stainless steel
Answers
Answer:
1. 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 primarily of copper, commonly with about 12-12.5% tin and often with the addition of other metals (such as aluminium, manganese, nickel phosphorus or silicon.
zinc varying from 5% to 40%.
2. Bronze is an alloy consistingor zinc) and sometimes non-metals or metalloids such as arsenic,
3. A higher tin composition gives the solder higher corrosion resistances,
but raises the melting point. Another common composition is 11% tin, for soldering components that are
37% lead, 42% bismuth, and 10% cadmium. This combination has a low melting point and is useful
sensitive to heat
4. In metallurgy, stainless steel, also known as inox steel or inox from French inoxydable (inoxidable), is a steel alloy, with a minimum of 10.5% chromium content by mass and a maximum of 1.2% carbon by mass.
