Wholesale 99% Pure Solid Copper Sphere Bearing Balls 4mm 6mm 8mm 10mm
The brass ball produced mainly used H62 copper,usually in kinds of electric,switch,carburetor.
Brass ball is soft so it is easy to be drilled,then usually used in valve and art ware.
Diameter | 0.5mm / 50.8mm | ||
Material | Brass ball H62, H65 / Copper ball 99%CU | ||
Feature | Brass balls show fairish mechanical performance, good corrosion
resitance, excellent electrical properties. They generate low frictions. Balls are
provided in the passivated condition. | ||
Application | 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 atmospheres, petroleum
products, alcohols. 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. |
