 One. The GB Hpb59-1 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. 

 Imports C3710 material name 
 Commonly known as the 59-1 lead brass Hpb59-1, also known as free-cutting brass 12 kinds of the following, the company mainly engaged in the production agent lead brass 
 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, C3710, C3771, C3561, C3710, C2603. 
 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: HPb59-1 copper mass fraction of 59%, with main plus elements such as lead mass fraction of 1%, the margin for lead zinc brass. 

 3 GB Hpb59-1 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. 

 Imports C3710 Lead 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.
