1. Detailed description:
Resistance alloy cables are used for heating resistance elements. Haide electrothermal alloy produced high strength for high purity, low impurity resistivity stability, small temperature coefficient, surface body in good condition, and the highest intensity and high temperature and good processing performance can weld steels of the nature of the varieties of the complete specifications. Widely used in metallurgy, industrial kitchens, household appliances, machinery and electronic manufacturing industries to make heating resistance materials.
1. FeCrAl alloys of electric heating resistance with high electrical resistivity, small coefficient of resistance temperature, high operational temperature, good resistance to corrosion under high temperature and especially suitable for use in the atmosphere with sulfur and sulfur, more price Low, it is normally used in electric industrial furnaces, household appliances, remote infrared device ideal heating material.
FeCrAl type: 1Cr13AI4, 0Cr21AI4, 0Cr21AI6, 0Cr25AI5, 0Cr21AI6 Nb, 0Cr27AI7Mo2, etc. Serious electric flat belt, electric flat wire
2. Nickel-chromium alloy with electrothermal iron resistance and high resistivity, good body sexual surface. At high temperature and high intensity, and good performance and processing can weld nature widely used in matellurgy, electrical, mechanical components and electrical manufacturing industries to make heating resistance materials. Ni-Cr type: Cr20Ni80, Cr15Ni60, Cr20Ni35, Cr20Ni30 , Cr25Ni20, etc. Serious electric flat belt, flat electric wires.
