What is brass (brass)
Brass classification brass material if it is composed of two or more elements of a variety of alloys known as special brass. Such as lead, tin, manganese, nickel, iron, silicon composed of copper alloy. Brass has a strong wear resistance. Special brass, also known as special brass, it is high strength, hardness, chemical resistance and strong. As well as the mechanical properties of cutting is also more prominent. Brushed by the brass pulled into a seamless, soft, wear-resistant performance. Brass seamless pipe can be used for heat exchangers and condensers, low temperature piping, submarine transport pipes. Manufacture of sheet metal, bar, bar, pipe, casting parts. Copper in 62% to 68%, strong plastic, manufacturing pressure equipment.
Brass rods according to the type of alloy elements contained in brass, brass is divided into ordinary brass and special brass two. The brass used for press working is called deformed brass.
Brass Features Brass is an alloy of copper and zinc. The simplest brass is a copper-zinc binary alloy, called simple brass or plain brass. Changing the content of zinc in brass can give brass with different mechanical properties. The higher the zinc content in the brass, the higher the strength, the plasticity is slightly lower. Industrial use of brass zinc content of not more than 45%, high zinc content will produce brittle, so that the performance of the alloy deteriorated. In order to improve the performance of brass, in addition to a single brass by adding other alloy elements of brass called special brass. Commonly used alloy elements are silicon, aluminum, tin, lead, manganese, iron and nickel. Alcohol in brass can improve the yield strength and corrosion resistance of brass, slightly lower plasticity. Brass with less than 4% aluminum has good processing, casting and other comprehensive performance. The addition of 1% tin in brass can significantly improve the ability of brass to resist seawater and ocean atmospheric corrosion, hence the "navy brass". Tin also improves brass cutting performance. The main purpose of brass plus lead is to improve the machinability and improve wear resistance, and lead has little effect on the strength of brass. Manganese brass has good mechanical properties, thermal stability and corrosion resistance; in the manganese brass aluminum, but also can improve its performance, get smooth surface castings. Brass can be divided into casting and pressure processing two types of products.
