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.

Topright Brand FeCrAl Resistance Heating alloys with high electrical resistivity, temperature coefficient of resistance is small, high operating temperature. good corrosion resistance under high temperature, and particularly suitable for use in a gas containing sulfur and sulfides, low price.
