Sell Powder Metallurgy

详情

Powder Metallurgy has already won more and more recognition in manufacturing method of contact material and became a main method for making Power Contact such as AgW、CuW、AgWC、AgWCW、AgNi、AgNiC、AgC etc. Their characters as follows:

（1）The component and quality of contact production made by Powder Metallurgy are more easy to control comparing with other manufacturing method, because it can ensure uniformity of contact function. It is beneficial for ameliorating metallographic organization and improving function of contact materials by using advanced methods: chymic cladding, chemical sedimentation, pulverization, mechanization alloy.

（2）Adopting the manufacturing methods of sinter and extrusion, their consistency can achieve *9.9%. Meanwhile, the second structure in silver base becomes fibre shape whose direction is vertical to the surface of Electrical Contacts, all these improve highly physical mechanism， arc corrosion resistance and low and stable resistance of the materials.

（3）AgW, CuW, AgWC contacts choose different powder materials with adding inside Ni, Co mineral and by using pre-sinter and active sinter technology then improve their consistency and ameliorate electrical function of contact materials
