hpb63-0.1 is a special type of lead brass, which has lower machinability than HPB63-3. This is mainly due to its higher lead content, which makes the material softer and requires more care when cutting. In addition, since this material cannot be hot-pressed, its shape and structure need to be determined at the time of casting or cold working. 
Despite HPB63-01 has low machinability, but its excellent anti-friction properties make it easy to weld and fiber weld, which makes it excellent in situations where good lubrication and connection are required. At the same time, it has good stability against general corrosion, and can maintain stability for a long time in many corrosive environments. However, it should be noted that this material has a tendency to corrode and crack, so it needs to be used with caution in some highly corrosive environments. 
hpb63-0.1. The main use is as a structural part, it can be used in a variety of occasions that need to withstand a certain amount of pressure and friction. In terms of chemical composition, it has a copper content of 615～63.Between 5%, the amount of zinc depends on the manufacturing process, and the rest of the components such as lead, phosphorus, aluminum, iron, antimony and bismuth are limited. 
In terms of mechanical properties, HPB63-01 The tensile strength b (MPa) 370, the elongation δ10 (%15), the elongation δ5 (%18. These performance parameters ensure that the material has sufficient strength and ductility during use to meet a variety of needs. The specimen size is generally the diameter or the distance to the opposite side 5 20.
