0.5-10.0mm TKA1 TKYZ FECRAL Resistohm 145A1 TKAPM High Temperature Heating Resistance Wire for Industry Furnace
0.1-10.0 mm TKYZ FECRAL Heating Resistance Wire for Industry Furnace Edge Brake Resistor
FECRAL is a type of high-temperature heating alloy that is primarily composed of iron (Fe), chromium (Cr), and aluminum (Al). This alloy is known for its exceptional resistance to oxidation and corrosion at elevated temperatures, making it suitable for various high-temperature applications.
The key characteristics of the FECRAL alloy include:
-
Composition:
- FECRAL 23/6
-
High-Temperature Oxidation Resistance:
- The combination of chromium and aluminum in the FECRAL alloy allows for the formation of a stable, adherent, and self-healing oxide layer that protects the underlying metal from further oxidation.
- This oxide layer is effective at temperatures up to around 1,200°C, making FECRAL a suitable choice for applications involving prolonged exposure to high temperatures.
-
Mechanical Properties:
- FECRAL alloys exhibit good mechanical strength, hardness, and creep resistance at high temperatures, ensuring the structural integrity of components.
- The alloy's thermal stability and resistance to microstructural changes at elevated temperatures contribute to its long-term performance.
-
Applications:
- FECRAL alloys are commonly used in high-temperature furnace components, such as heating elements, burner nozzles, and heat exchanger tubes.
- They are also employed in the aerospace industry for components like turbine blades, afterburner parts, and rocket nozzles.
- In the petrochemical industry, FECRAL alloys are used for catalytic converters, fluidized bed reactors, and other high-temperature equipment.
The specific composition of FECRAL alloys can be tailored to meet the requirements of different applications, with varying amounts of iron, chromium, and aluminum, as well as the addition of other alloying elements like yttrium or zirconium to further enhance the alloy's properties.
Overall, the FECRAL alloy's exceptional high-temperature oxidation resistance, mechanical strength, and thermal stability make it a valuable material choice for a wide range of high-temperature engineering applications.
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.
