Brass row characteristics and classification

Brass is an alloy of copper and zinc. the only brass could be a copper-zinc binary alloy called simple brass or plain brass. Different mechanical properties of brass will be obtained by changing the content of zinc in brass. the upper the content of zinc in brass, its strength is higher, slightly lower plasticity. The zinc content of brass employed in industry isn't quite 45%, and also the higher zinc content will produce brittleness, in order that the alloy performance deteriorates. so as to boost the performance of brass, the brass with other alloying elements is termed special brass. Common alloying elements include silicon, aluminum, tin, lead, manganese, iron and nickel. The yield strength and corrosion resistance of brass may be improved by adding aluminum to brass, and therefore the plasticity will be reduced slightly. Brass containing but 4% aluminum has good processing, casting and other comprehensive properties. Adding 1% tin to brass can significantly improve the power of brass to resist sea water and Marine atmospheric corrosion, so it's called "naval brass". Tin may also improve the machining performance of brass. the most purpose of adding cause brass is to enhance the machinability and wear resistance. Lead has little effect on the strength of brass. Manganese brass has good mechanical properties, thermal stability and corrosion resistance. The properties of manganese brass may be improved by adding aluminum to that, and also the casting with smooth surface are often obtained. Brass are often divided into casting and pressure - working products. Product specifications complete, price concessions, intact packaging, pure copper, good straightness, large inventory, can provide material certification and SGS report.

Brass plate with zinc because the main element of the copper alloy, with beautiful yellow, collectively stated as brass. Copper zinc binary alloy is named ordinary brass or simple brass. Brass with over three yuan is termed special brass or complex brass. Brass alloys containing but 36% zinc are composed of solid solutions and have good cold working performance. as an example, brass containing 30% zinc is usually accustomed make shell casings, commonly referred to as shell brass or seventy-three brass. Brass alloys with zinc content between 36 and 42% are composed of and solid solutions, of which the foremost commonly used is hexagonal brass with zinc content of 40%. so as to enhance the performance of ordinary brass, other elements are often added, like aluminum, nickel, manganese, tin, silicon, lead then on. Aluminum can improve the strength, hardness and corrosion resistance of brass, but reduce the plasticity, so it's suitable for Marine condensing tubes and other corrosion resistant parts. Tin can improve the strength of brass and corrosion resistance to seawater, so it's called Admiralty Metal, used for ship thermal equipment and propellers. Lead can improve the cutting performance of brass. This free cutting brass is usually used as a clock part. Brass castings are often accustomed make valves and plumbing fittings.
