Copper-graphite
@electrical contacts
Characteristic: Copper-graphite (cuc) has better in anti-welding and resistant arc erosion.

Silver-tungsten
@electrical contacts
Characteristic:
Silver-tungsten (agw) has excellent in arc resistant erosion, anti-welding and electric conductivity. Silver-tungsten contact materials are produced by an improved infiltration technique and powder metallurgical method. There are silver entiched at base for facilitate brazing.

Silver-tungsten carbide
@ electrical contacts
Characteristic:
The silver-tungsten carbide (agcw) contact materials provide good resistance to arc erosion and welding. In addition, it possesses more stable contact resistance due to its better resistance to oxidation. And the contacts combine small-volume, light-weight, silver economized etc.

Silver-graphite
@electrical contacts
Characteristic:
The silver-graphite (agc) possesses good breaking capacity and resistivity against welding. And low-stable contact resistance. The method of production are sintering and repressing process (p) sintering and extruding process (q).

Copper-tungsten
@electrical contacts

Characteristic:
Copper-tungsten (cuw) contact material provides good resistancs to arc erosion and welding and high strength produced by infiltraton process.
