Introduction:

0Cr15Al5 is a high resistance alloy, also known as heater wire alloy. Its main components include iron (Fe), chromium (Cr), aluminum (Al) and small amounts of other elements. This alloy has excellent high temperature resistance and electrical resistance properties and is therefore widely used in thermal equipment and electric furnace heating elements.

0Cr15Al5 alloy has good oxidation resistance and can form a dense oxide protective film in high temperature environments, thus effectively preventing further oxidation of the material. This alloy also has good mechanical properties and weldability, making it very popular in the manufacture and application of heating elements.

The heater wire is a wire made of 0Cr15Al5 alloy and has a certain degree of elasticity and plasticity. Its cross-sectional shape is usually circular or rectangular, and different sizes and lengths can be customized according to specific application requirements.

0Cr15Al5 heater wire is widely used in industrial heating fields, such as electric furnace heating coils, hot blast furnace heating elements, industrial ovens, electric heaters, heat treatment equipment, etc. Due to its excellent antioxidant properties and resistance characteristics, 0Cr15Al5 heater wire is able to work stably in high temperature environments and provide uniform heating effects.
