4MM 5MM 1.588MM Brass Or Solid Copper Ball H62 Metal Sphere For Pumps and Valves
 

 

Brass balls show fairish mechanical performance, good corrosion resitance, excellent electrical properties.
 
 
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.
 
 
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 petrochemical 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.
