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.
