Possible Applications:

Automotive:

Shock absorbers, doors, bonnets and tailgate hinges, steering columns, clutches, gearbox selector fork guides, wiper arms, power steering pumps, pedal bushes, ABS equipment, etc.

Industrial:

Aerospace, agricultural equipment, construction equipment, material handling equipment, forming machines-metal, plastic and rubber, office equipment, medical and scientific equipment, packaging equipment, pneumatic and hydraulic cylinders, pumps and motors, railroad and tramway’s, textile machinery, valves, etc.

Applications:

1. Low demand to the shape even no surface hardness treatment, which lower the cost of the mating components.

2. No absorption to water/oil, small coefficient of thermal emption, good thermal conductivity and size stability.

3. The back of the steel strip can be plated with various metals, anti-corrosion.
