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