Powder metallurgy W - Cu contact materials
is a key element of the high and low voltage switch actuator, than copper
switch capacity increased nearly 3 times, life is increased from 5 to 17 times;
powder metallurgy, Ag CDO contact material used in the AC contactor and strong
starter, life than silver improve 5 ~ 12 times.
Only this one can save more than ten tons
of silver per year.
Powder metallurgy CuCr contact material has
excellent comprehensive performance, is the best material in the vacuum switch
of medium voltage electrical equipment, Fe CuCrMoFe to improve the pressure
resistance. Mo increased the conductive ability, improve breaking performance
in the powder metallurgy of all kinds of batteries, especially nickel metal hydride
batteries (Ni MH) are widely used for the field of video recorders, mobile
phones, mini camera.
At present, China has nearly 30 units of
production battery, about 30 million / year. But the stability of the material
is poor, the yield is low, the price is also higher, and no matching of
electronic equipment.
