ASTM B603,DIN17470,JIS C2520,GB/T1234.
Material:NiCr35/20.
Application:Nichrome, a non-magnetic alloy of nickel and chromium, is commonly used to make resistance wire.
1.has a high resistivity and resistance to oxidation at high temperatures
2.Nichrome wire is commonly used in ceramics as an internal support structure
3.withstand the high temperatures that occur when a clay work is fired in a kiln.
Packaging:A full range of flexible packaging options are available to fit your individual requirements.
