Brass is an alloy, a combination of copper and zinc. It contains around 67% copper and 33% zinc.
Commonly, Lead is also added to brass at a concentration of around 2%. Lead improves the machinability of brass.
Lead brasses have excellent machining qualities and can be blanked, sheared and milled.
Brass does not become brittle at low temperature like mild steel.
Brass also has excellent thermal conductivity. Its electrical conductivity ranges from 23 to 44% that of pure copper.
Copper is the main component, and brass is usually classified as a copper alloy
Brass is stronger and harder than copper but not as strong or hard as steel
Uses of brass metal
Brass metal is used to make water fittings, screws, radiators, musical instruments and cartridge casings for firearms. Brass is a fairly strong metal but relatively malleable, so it is easily mauled into a number of different …show more content…
The addition of tin also improves the corrosion resistance. Iron makes the brass harder and makes the internal grain structure smaller to make proper shape of brass. Arsenic and Antimony are sometimes added to brasses that contain more than 20% zinc to inhibit corrosion. Other materials like manganese, silicon and phosphorus in a very small amount.
Manufacturing process of brass involved combining the appropriate raw materials into a molten metal, which is allowed to solidify. After this process solidified metal are then changed through a series of operations to produce the desired brass stock. Actual manufacturing process depends on the desired shape and properties of the brass stock as well as on the machines and practices used in different brass plants. A very typical manufacture process used to produce brass sheet and strip.
The metal has both good heat and electrical conductivity and it is wear and spark
