0Cr23Al5 Spring For Electric Furnace Wire Fecral Heating Element In High Resistivity
Our company mainly produces high-temperature heating strip with low impurities, high purity, good surface
oxidation resistance, stable resistivity, corrosion resistance, good processing performance and high temperature
strength and weldability. The products can be directly processed into winding, Z-shaped, spiral, etc.,
and widely used in metal smelting, mechanical manufacturing, industrial electric furnaces, small electric furnaces,
muffle furnaces, household appliances, transportation and other industries to produce heating elements and
resistance components. Our product specifications are complete in advanced technology and guaranteed quality.
Welcome new and old customers to order!
