Product Introduction

0Cr27Al7Mo2 Wire is a high resistance electric heating alloy wire, the main chemical composition is carbon content ≤0.05%, silicon content ≤0.40%, manganese content ≤0.20%, phosphorus content ≤0.025%, sulfur content ≤0.020%, chromium content 26.5%~27.8%, nickel content ≤0.60%, aluminum content 6.0%~7.0%, molybdenum content 1.8%~2.2%, the balance is iron. It has a high resistivity of 1.53±0.07μΩ·m (20℃), a density of 7.1 g/cm³, a melting point of about 1520℃, and a maximum operating temperature of up to 1400℃.
This alloy wire has excellent oxidation resistance. Due to the high content of chromium and aluminum, it can form a dense Al₂O₃ oxide protective film at high temperature, and has high oxidation resistance and thermal strength below 1250℃. The addition of molybdenum further improves the temperature resistance of the material. 0Cr27Al7Mo2 Wire also has a low temperature coefficient and can maintain a stable resistance value at different temperatures. It is widely used in the manufacture of electric heating elements, such as heating elements for heat treatment furnaces with a use temperature below 1250°C, especially for continuous furnaces such as stainless steel solution furnaces. In addition, it is also used for heating materials in industrial electric furnaces, household appliances, infrared heating devices, as well as heating elements and resistors in the fields of metallurgy and machinery manufacturing.
