Product Material

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.

General Description

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.

Application Scope

1.AgW series : All kinds of omnipotence breakers ,plastic breakers, heavy charge AC\DC contactorsand switches.

2.CuW series: Widely used in high voltage circuit breaker .

3.AgWC,AgWCC series: Mainly used in high electricity charge switchgear such as circuit breaker ,leakage switch .Generally they are used with AgNi,AgWC .

4.AgNi series: Widely used in DC\AC relay ,designation switch ,contactor ,light switch ,thermal controller ,timer of washer etc.

5.AgNiC series: Widely used in omnipotence breakers such as DW45 intelligence coupling with AgW.

6.AgC series: Mainly used in protective switch such as miniature breaker ,creepage protective switch or motor protective switch with coupling contact in AgW.

7.Silver oxidized metal series : Mainly used in middle and large capacity relay ,contactor middle and small capacity  low voltage breaker ,DC\AC switch ,driver creepage protective switch etc.
