NiCr8020/ NiCr7030 / NiCr3020/ NiCr6015 Wire/Strip Used for Resistor Elements in High Temperature Applications
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.
NiCr Type:Cr20Ni80,Cr15Ni60, Cr20Ni35, Cr20Ni30, Cr25Ni20 etc.Series electric flat belt, electric fire wire.
