As we known,powder metallurgy is a material and energe saving process,it could be adopted to produce household appliance parts with special properities.China as a large household appliance manufacturing and consuming country,but by comparing with other advanced countries,not only on the quantity side of powder metallurgy parts,but also on the quality side of powder metallurgy parts,we knew that there is a large gap.Thus developing the powder metallurgy material on household appliance parts in domestic China has become one difficult but important task.
Powder metallurgy material W-Cu contact material is a high and low voltage switch actuator key element;Powder metallurgy Ag—CdO contact material has been applied on AC contactor and strong starters products,and its lifetime is 5-12 times longer than silver material.Powder metallurgy CuCr contact material possesses excellent comprehensive properties,it is the best material used on medium voltage electrical vaccum switch.The Fe element of CuCrMoFe material could improve the pressure resistance property and the Mo element could promote the electricity conductivity.
In recent years,powder metallurgy ceramic material has been applied widely on household appliance products,such as powder metallurgy indium tin oxide (Indium-Tin Oxide, referred to as ITO) film,it is a semiconductor ceramic film,It is because of its special optical and electrical properties ,thus it is widely used in flat panel displays, solar cells, heat mirrors and hot plates used on cooking and heating elements and so on.
