Other powder metallurgy functional materials for household appliances


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.
