Powder Metallurgy Electrical Contacts

1,The composition and quality of contact production made by Power Metallurgy are easier to control than other manufacturing method ,then ensure uniformity of contact function .It is beneficial for ameliorating metallographic organization and improve the function of contact materials by using advanced methods: chymic cladding ,chemical sedimentation ,pulverization ,mechanization alloy .
2,Adopting the manufacturing methods of sinter and extrusion ,the density can be 99.9%.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 use different powder materials with adding inside Ni ,Co mineral and by using persintering and active sintering technology to improve the consistency and ameliorate electrical function of contact materials .
