Main Advantage and Application
1. Nickel-chromium, nickel-chromium alloy with high and stable
resistance, corrosion resistance, surface oxidation resistance is
good, a better under high temperature and seismic strength, good
ductility, good workability and weldability.
2.Our Products widely apply to chemical industry, metallurgy
mechanism, glass industry, ceramic industry, home appliance area
and so on.
