Injection Molding Powder Metallurgy Copper-Based Parts is frequently used in the powder metallurgy process. It is very common as one of the raw materials of powder metallurgy. What are the characteristics of this powder and what should be paid attention to in order to make the result better?
During the manufacturing process of copper-based powder, one of the raw materials of powder metallurgy, the bulk copper powder is sintered at high temperature because the spherical powder is not subjected to external force. In this process, the sintering problem is also strictly controlled within a certain range, so the spherical powder remains spherical, and pores are formed between the particles. The porosity and the scale of the pores can be selected.
Due to the manufacturing process, the copper-based powder has the characteristics of high filtration accuracy, stable pores and low pressure loss. And there is no phenomenon that the pore size changes with pressure. It is because of the effective removal of suspended solids and particulates that there is such a high filtration accuracy and a good purification effect.
The copper-based powder has high porosity, uniform and smooth pores, so its initial resistance is small, and it is easy to blow back; and it has strong regeneration ability and long service life. It is especially suitable for places with high uniformity requirements such as fluid distribution and uniform treatment . In addition, copper-based powder has high mechanical strength, good rigidity, good plasticity, oxidation resistance, corrosion resistance, etc., and it is more widely used.
Among the copper-based powders, copper powder occupies the vast majority of the composition, and the base material is copper powder. But some alloying elements are added, such as iron, carbon, etc. Therefore, the commonly used copper-based powder alloys in powder metallurgy include Sn10 powder, 663 bronze powder, etc., or materials obtained by adding a little graphite powder and lubricant according to their own needs.
All in all, the copper-based powder not only has excellent performance, but also is more convenient to prepare and use, providing an ideal raw material for the development of powder metallurgy technology.
