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 ramways, 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.
