Nicr30/20 Alloy Wire High temperature alloy
Ni30Cr20 Nichrome Wire for Resistance Wire , Resistance Heating Strip
Application:Nichrome, a non-magnetic alloy of nickel and chromium, is commonly used to make resistance wire.
Because it has a high resistivity and resistance to oxidation at high temperatures. When used as a heating element, resistance wire is usually wound into coils.
Nichrome wire is commonly used in ceramics as an internal support structure to help some elements of clay sculptures hold their shape while they are still soft. Nichrome wire is used because of its ability to withstand the high temperatures that occur when a clay work is fired in a kiln.
