3. What is Powder Metallurgy contact?
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,AgWCC,AgNi,AgNiC,AgCetc.Their characters as follows:
1,The component and quality of contact production made by Power
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 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 choose different powder materials with adding inside Ni ,C0 mineral and by using per-sinter and
active sinter technology then improve their consistency and
ameliorate electrical function of contact materials .
