Resistant Heater Electric Furnace 0Cr19al3 Fecral Heating Elements Wire

Introduction:

0Cr19Al3 heater wire is a high resistance alloy, also known as grate bar alloy. It is composed of iron (Fe), chromium (Cr), aluminum (Al) and small amounts of other elements. The alloy's excellent high temperature resistance and electrical resistance properties make it widely used in thermal equipment and electric furnace heating elements.

0Cr19Al3 heater wire alloy has excellent oxidation resistance and can form a dense oxide protective film in high temperature environments, effectively preventing further oxidation reactions. In addition, it 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 0Cr19Al3 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 needs.
