Cr15Ni60 Alloy 8.7 g/cm3 Excellent Resistance Characteristics High Temperature Oxidation Resistance

Cr15Ni60 Alloy: 8.7 g/cm3 Excellent Resistance Characteristics And High Temperature Oxidation Resistance

NiCr Series

Cr15Ni60 nickel-chromium alloy is a high-performance resistance heating material with excellent high-temperature oxidation resistance and stability. It is widely used in aerospace and industrial electric furnaces. Its density is 8.7 g/cm³, its melting point is as high as 1400℃, and its maximum operating temperature can reach 1150℃. The resistivity of the alloy is 1.12±0.05μΩ·m at 20℃, its tensile strength is 600-700 MPa, and its elongation is ≥20%, showing good mechanical properties. Cr15Ni60 alloy can maintain a stable resistance value in high temperature environment, and the dense oxide film formed on the surface gives it excellent corrosion resistance. This alloy is suitable for the manufacture of electric heating elements, heating equipment and high-temperature sensors, especially in scenarios that require long-term stable operation.
