 Physical Constants

 

Density: Approximately 7.10 g/cm³.

Resistivity: At 20℃, it is 1.35 μΩ·m.

Maximum operating temperature: up to 1250℃.

 

 

 

Characteristic

 

Excellent oxidation resistance: Cr15Al5 alloy can form a stable alumina layer at high temperatures to protect the matrix from oxidation.
High resistivity: suitable for the manufacture of resistance components, such as electric heating wires.
Good mechanical properties: maintain good mechanical strength at high temperatures.

 

 

 

Corrosion Resistance

 

Oxidation resistance: A dense protective layer of alumina can be formed at high temperatures to prevent further oxidation of the material.
Corrosion resistance: It shows good corrosion resistance in high temperature environments, especially in atmospheres containing sulfur and sulfide

 

Application

 

Industrial heating equipment: widely used in industrial furnaces, electric heating elements, etc.
Household appliances: Used for heating elements in electric heaters, electric blankets and other household appliances.
Nuclear energy field: Due to its excellent high-temperature oxidation resistance and corrosion resistance, it is also considered for use in some components of nuclear reactors.
