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.
