0.1-10.0 Mm TKYZ FECRAL Heating Resistance Wire For Industry Furnace Edge Brake Resistor
0.1-10.0 mm TKYZ FECRAL Heating Resistance Wire for Industry Furnace Edge Brake Resistor
Some key characteristics of high-temperature heating alloys include:
-
Elevated Melting Point: These alloys have high melting points, typically in the range of 1,000°C to 1,600°C, which allows them to maintain their structural integrity at high operating temperatures.
-
Oxidation Resistance: High-temperature heating alloys are engineered to resist oxidation and corrosion at elevated temperatures, ensuring long-term performance and durability.
-
Mechanical Strength: The alloys are designed to maintain their mechanical properties, such as tensile strength, creep resistance, and fatigue life, even at high temperatures.
-
Thermal Stability: These alloys exhibit minimal microstructural changes or phase transformations when exposed to high temperatures for extended periods, ensuring consistent performance over time.
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.
