heater furnace wire Resistohm 145 145A1 kanthal A1 AF APM TKYZ FECRAL Heating resistance wire
TKYZ product is a new product developed after TK1 product, which has been widely used in high temperature electric heating alloy materials in recent years. Compared with TK1, its purity is further improved and its oxidation resistance is further optimized. With the special rare earth element combination and unique metallurgical manufacturing process, the material has been recognized by domestic and foreign customers in the field of high temperature and heat resistant fibers. Successful application in ceramic sintering, diffusion furnaces, industrial furnaces with high power density and high temperature.
