 1 GB HPb61-1 lead brass rods Overview 
 Brass is composed of copper and zinc alloy, if only by copper, zinc and called the general composition of the brass on brass. In order to improve the performance of ordinary brass alloy, added trace metal elements such as lead. Lead can improve brass cutting; that used for cutting brass watch parts. Brass castings used to make valves and pipe fittings. 

 (2) the name of imported materials C3710 
 HPb61-1 commonly known as the 61-1 lead brass rods, brass cutting, also known as 12 species, our company mainly engaged in producing agents of lead brass rod as material, 
 HPb89-2, HPb66-0.5, HPb63-3, HPb63-0.1, HPb62-3, HPb62-2, HPb62-0.8, HPb61-1, HPb60-2, HPb59-3, HPb59-2, HPb59-1, HPb58- 2.5, C3560, C3713, C4622, C3601, CuZn37, C3604, C3710, C3710, C3771, C3561, C3710, C2603. 
 Code: the "H + main elements plus sign (except for zinc and outside) the mass fraction of Cu + + + main plus elements of the mass fraction of the mass fraction of other elements," said. 
 Such as: HPb61-1 that the mass fraction of copper, 61%, with the main elements such as lead increases the mass fraction of 1% margin for the lead-zinc brass rods. 

 3 GB HPb61-1 lead brass rod features 
 Not actually dissolve lead brass, the state was free distribution of particles on the grain boundaries. Leaded brass rods and their organizations α (α + β) two. α lead brass rods harmful effects of lead larger, high-temperature plasticity is very low, it can only be cold or hot extrusion deformation. (Α + β) brass rod of lead at high temperature with good plasticity, can be forged. 

 4 brass rods imports C3710 Lead Scope 
 Leaded brass rod is extremely important, the most widely used one of a complex brass, it has excellent cutting performance, wear resistance and high strength, mainly used in mechanical engineering in a variety of connectors, valves, valve stem Bearing, in which the valve forging billets, lock industry, the watch industry are the three key markets, low cost lead brass rod is an important prerequisite for its widespread application, it can accommodate a variety of alloy composition of alloying elements, and content requirements are relatively relaxed, but also for the utilization of copper alloy materials basis.
