Nichrome wire mesh (aka Nichrome 80-20) is a nickel-chromium alloy, with a small silicon (1.25%) addition, originally designed as a high-performance electrical resistance alloy. In the wire cloth world, Nichrome V is used in high-temperature settings, and its high chromium (~80%) and nickel (~20%) composition gives it good oxidation resistance up to ~2150°F. Given the low temperature coefficient of resistance that Nichrome 80-20 wire mesh possesses, it is able to heat up quickly, maintain stable temperatures, and handle fluctuating temperatures in its environment.
