STA is a leading manufacturer of open coil heating elements. Resistance Wire.com was created to provide an easy and affordable way for manufacturers, hobbyists and engineers to purchase resistance wire products in the form and package they need. We have hundreds of spools in stock and ready to ship in a variety of alloys, gauges, and lengths.
Resistance heating wire .we have fecral kanthal wire ,nicr nikrothal wire and flat wire .The wire is supplied on spools, in coils, in pail pack or as straightened lengths and available with or without coating.
iron-chromium-aluminium (FeCrAl) kanthal alloys in wire and ribbon (flat wire) form. More information about each type of resistance alloy and resistance heating alloy, such as chemical composition, is available in the datasheet for the respective grade.
Nichrome nikrotha heating wire: Cr20Ni80, Cr30Ni70, Cr15Ni60, Cr20Ni35, Cr20Ni30.
