Product Introduction
Topright Brand Resistance Alloy Wires is used for electrical heating element. Topright produced high-resistance electrothermal alloy products for the high-purity, low impurity resistivity stability, temperature coefficient small, superficial body Sexual good, and the higher intensity and high temperature performance and good processing may welding nature steels varieties specifications complete. Widely used in metallurgy, industrial stoves, household appliances, machinery and electronics manufacturing industries do heat resistance material.
Nickel chromium alloy with iron resistance electrothermal high resistivity, surface body sexual well. At high temperature and high intensity, and a good performance and processing may welding nature widely used metallurgical, electrical, mechanical components and electrical manfacturing industries for doing heat resistance material.
