Product Display

99% Cu copper balls 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.

Copper balls are used in galvanic applications and in the field of electronic industry.

Copper balls have good corrosion resistance in marine and industrial atmospheres, steam, alkali, neutral saline solutions. They do not resist in contact with oxidizing acids, halogens, sulphides, ammonia, sea water.
