High temperature alloy soft bright Cr30Ni70 wire heat resistant for oven

High temperature alloy soft bright Cr30Ni70 wire heat resistant for oven
Nickel-chromium, nickel, ferrochrome alloy wire with electric high temperature oxidation resistance, high strength, not soften and a series of advantages. When used in a long time, the same type and the permanent elongation is very small, which is more Cr20Ni80 alloy with excellent comprehensive properties, is to produce high-quality varieties of choice for electric components.
