

Among the vast family of metal alloys, 3J21 stands out with its unique cobalt-based composition and outstanding performance characteristics. It has a significant role in the fields of aviation, aerospace, and precision instrument manufacturing. As a high-performance cobalt-based alloy, 3J21 possesses remarkable elasticity, corrosion resistance, high-temperature stability, and non-magnetic properties. These features make it one of the indispensable materials in modern industry.

FEATURE

1. Non-magnetic: This property makes 3J21 alloy highly useful in magnetic-sensitive applications, such as magnetic sensors and magnetic shielding fields.

2. Corrosion resistance: In various media, 3J21 alloy exhibits extremely strong corrosion resistance, effectively resisting chemical corrosion such as oxidation and sulfidation.

3. High elasticity and fatigue resistance: Suitable for components that require repeated deformation, such as elastic elements and precision instruments.
