This is nichrome wire that can be used in many applications in the classroom or lab. It is a low nickel (0.5%), high iron alloy of Nichrome that allows for laboratory uses. It’s makeup is 0.5% Ni, 15% Cr, 4% Al, Balance Fe. Maximum operating temperature is 1150°C. Density is 6.74g/cm^3
Many industrial and hobby hot wire foam cutters also use Nichrome wire. Nichrome wire is also 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.
Note: The wire is sold by weight. The lengths are approximations based on the density, weight, and thickness of the wire.
