Product Description
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.


Also, with advanced equipment and technology, we can serve you other products as follows:
1. Super alloys (Casting master alloy, deformation super alloy and so on).
2. Corrosion resistant alloy.
3. Welding wire.
4. Precision alloys (soft magnetic alloy, expansion alloy and so on).
5. High resistance alloys for electrical heating.
