Resistance Heating Alloys

Resistance Heating Alloys Resistance heating alloys are one of the main products of our company, they are classified into two categories: Fe-Cr-Al alloys and Ni-Cr. These alloys are widely used in making industrial heating equipments and domestic heating appliances. All resistance heating alloys manufactured by our company are distinguished by uniform composition, high resistivity, accurate dimension, long operating life and good processability. Consumers can select the suitable grade according to different requirements. SG-GITANE'S resistance heating wire 0Cr25Al5 obtained the title of excellent grade product from the China Ministry of Metallurgical Industry. In 1983, the company's resistance heating wire HRE awarded the second rate prize for the progress in science and techology from Beijing Municipality.Size range Wire 0.03-10.00mmWire rod 5.50-12.00mm RibbonThickness 0.05-0.35mm Width0.50-4.50mm StripThickness 0.50-2.50mmWidth 5.0-48.0mm Hot rolled stripThickness 4.0-6.0mmWidth 15.0-38.0mm PropertiesHRE0Cr21Al6Nb0Cr25Al50Cr23Al50Cr19Al50Cr19Al31Cr13Al4Cr20Ni80Cr15Ni60Nominal composition(%)Cr24.021.025.022.019.019.013.520.015.0Al6.06.05.35.05.03.75.0FeRestRestRestRestRestRestRestNiRestRestMax.continuous operating temperature()14001350130012501200110095012001150Electrical resistivity at 20(μ·Ω·m)1.451.431.401.351.331.231.251.091.11Temperature factor of the resistivity10001.031.031.051.061.051.171.131.041.1012001.041.041.061.071.061.191.141.051.118001.041.041.061.081.061.071.13Density(g/cm³)7.107.107.157.257.207.357.408.308.20Melting point(approx.)()150015001500150015001500145014001400Tensile strength(approx)(N/mm²)750750750750750750750750750Elongation at rupture(%)161616161616162525Magnetic propertiesMagneticMagneticMagneticMagneticMagneticMagneticMagneticNilWeak
