Product Description
- FeCrAl Series
0Cr21Al6Nb alloy has the characteristic of high resistivity, low temperature resistance coefficient, high operating temperature, good anti-oxidation and anti-corrosion under high temperature.
- Electric furnaces and ovens
0Cr21Al6Nb resistance wire is commonly used in electric furnaces and ovens for both household and commercial cooking appliances. They are installed as heating elements inside the oven chamber, generating heat when electric current passes through, allowing for quick heating or baking of food.
- Water heaters
0Cr21Al6Nb resistance wire is also widely used in water heaters to heat the water in the tank. When the temperature in the tank drops, electric current passes through the resistance wire, generating heat to raise the water temperature to the set level for bathing, cleaning, and other purposes.
- Heating tubes and heating plates
In industrial applications, 0Cr21Al6Nb resistance wire is often used to manufacture heating tubes and heating plates for heating liquids, gases, or solid objects. These heating devices find widespread applications in industries such as chemical processing, food processing, pharmaceutical manufacturing, and more.
- Electronic devices
Some electronic devices also utilize 0Cr21Al6Nb resistance wire as heating elements, such as heating elements for printed circuit boards (PCBs), thermocouples, and more. These devices often require stable operation at specific temperatures.
