General Applications

General Applications

Brass resists corrosion from petroleum products and alcohol, hence Brass balls are used in valves, petroleum products, alcohol and electronic industry.

Aluminum balls are highly resistance to corrosion but has a low mechanical strength. These balls are used for electronic industry.

Other material are available upon request

In non ferrous we also stock ceramic balls we import sizes as follows:
