 A the GB Hpb66-0.5 lead brass Overview 
 Brass is an alloy composed of copper and zinc, if only by copper, zinc, brass called on ordinary brass. In order to improve the performance of ordinary brass alloy, add the trace metal elements such as lead. Lead can improve brass cutting; This cutting brass is used as a clock or watch parts. Brass castings used to make valves and pipe fittings. 

 Import C33000 material name 
 Hpb66-0.5, commonly known as 66-0.5 lead brass, also known as the leaded copper-zinc alloy, lead brass company mainly engaged in the production agent as follows, 
 HPb89-2, HPb66-0.5, HPb63-3, HPb63-0.1, HPb62-0.8, HPb62-3, HPb62-2, HPb61-1, HPb60-2, HPb59-3, HPb59-2, HPb59-1, HPb58- 2.5, C3560, C3601, C4622, C3713, C3604, C3713, C33000, C3771, C3561, C3710, C2603, C31400, C33000. 
 Code: H + main (in addition to zinc) + mass fraction of copper + main add the element mass fraction and element symbols + and the other elements of the mass fraction of. 
 Such as: the mass fraction of Hpb66-0.5 copper 66%, with the main plus elements such as lead content of 0.5% margin for zinc lead brass. 

 The GB Hpb66-0.5 Lead Brass features 
 Lead not actually dissolve in brass, was free particle state is distributed in the grain boundary. Α and (α + β) two kinds of lead brass according to their organization. α leaded brass due to the harmful effects of lead and high temperature ductility is very low, so only cold deformation or hot extrusion. Leaded brass (α + β) at high temperature with good plasticity, can be forged. 

 Import C33000 leaded brass scope of 
 The lead is extremely important, brass and one of the most widely used complex brass, it has excellent cutting performance, wear resistance and high strength, mainly used in mechanical engineering in a variety of fittings, valves, stem bearing to keep in hot forging valve blanks, lock industry, the watch industry is the three most important market, the cost of leaded brass is an important prerequisite for its wide application and can accommodate a variety of alloying elements in the alloy composition and content requirements relaxed, laid the foundation for the comprehensive utilization of copper alloy materials.
