Solid 99.99% Mirror Polished Copper Ball Brass Balls 13mm 14mm 14.28mm 15mm 15.875mm
Nearly pure copper balls, they show good mechanical and corrosion resistance properties, excellent thermal
and electric conductivity.
Small amounts of alloying elements as Cr, Zr, Ag, Cd, Mg, Sn allow to improve the mechanical properties.
Application: Copper balls are used in galvanic applications and in the field of electronic 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. |
