Production Description:
Such electrothermal alloy has stable structure and electrical physical property. It has so good high temperature mechanical property, fine cold plastic deformation and weldableness that brittle fracture won't occur even used for long. The alloy is widely used in manufacturing the household appliances and heating element whose working temperature is below 1000ºC. Moreover, it has long lifespan.
Density:8.40g/cm³
