HPb59-1铅黄铜棒是传统的易切削材料。随着社会生产力的发展,对材料的性能提出了新的要求,即适应高速切削,加工零件光洁,不带毛刺,降低刀具损耗。经研制,HPb58-3棒可以满足上述要求而又不降低机械性能,亦能承受适当的冷铆,冷镦变形,模锻,电镀加工。生产成本也略有下降。 HPb59-1 lead brass rod is a traditional cutting material. With the development of social productivity, the performance of the material put forward new requirements, that is, to adapt to high-speed cutting, machining parts and smooth, without burrs and reduce tool wear and tear. Developed, HPb58-3 rod to meet the above requirements without reducing the mechanical properties, can withstand the appropriate cold riveting, cold heading deformation, forging, plating processing. Production costs also declined slightly.
