Nichrome Resistance Wires Nichrome is basically an alloy made by mixing nickel and chromium in some fixed proportion. This is highly used industrial material especially as a resistance wire for heaters, and related devices. Our range of Resistance Wires are made in compliance with industrial standards. We also offer customization facility and with below given specifications Nichrome Wires can be obtained. Specifications: Ni-Cr resistance heating wire and strips electrothermal resistance wires Nichrome electrical alloy wires and strips resistance alloy wires or strips electrical heating wires Nickel-Chrome resistance heating alloy Nickel chrome wires and strips 1.
