Nichrome Alloy Electrical Resistance Wire Cr15Ni60 NiCr6015 For Resistor
Nichrome, a non-magnetic alloy that is commonly made up of 80% nickel and 20% chromium, has a resistivity ranging from 1.10 × 10−6 Ωm to 1.50 × 10−6 Ωm (0.00000110 Ωm to 0.00000150 Ωm) and a very high melting point (~1400 °C).
NiCr 60 15 (2.4867) is an austenitic nickel-chromium alloy (NiCr alloy) for use at temperatures up to 1150°C.
Is nichrome wire used in fuse?
Fuse is an important component of an electrical circuit to limiting the current through the electrical circuit for electrical equipment safety. Safety fuses are made of a conductor such as copper and nichrome wires.
