Multifunctional Fiberglass Wire Nicr80 / 20 For Heating elements
Fiberglass Insulated Nichrome Wre Which Is Widely Ued In Industrial Furnace,
The specification of fiberglass insulated nichrome wire
A.Features
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. The products are widely used in industrial furnace, metallurgy, machinery, household appliances and other industries producing heating elements and resistance elements
