BRASS BALLS

Brass balls show fairish mechanical performance, good corrosion resitance, excellent electrical properties. They generate low frictions.

Balls are provided in the passivated condition.

 

Applications

Special valves, industrial pumps and valves, electronic devices, safety switches, heating units, appliances, furniture rails.

They are used in the automotive, electronic and petrolchemical industry.

Corrosion Resistance

Good corrosion resistance in drinking-water, brackish water, sea-water (except at high flow rate), salt athmosferes, petroleum products, alcools.

Fairish resistance with respect to acids and alkali.

It does not resist in contact with hydroxides, cyanides, oxidizing acids.

As a general rule, corrosion resistance decreases as zinc content increases.
