furnace spiral heating resistance wire
Advantage
Our heating wire is of high quality with following features:
1. A quite reasonable price
2. Stable performance: High working temperature(The highest temperature can be 1400 C ), high strength under temperature, corrosion resistance, long life-span, allowable high surface load, small specific gravity, good formability and weldability.
