INTRODUCTION
These Balls are mostly used for non-bearing applications. Their properties of ductility, good corrosion resistance in moisture and electricity conductivity find them allied applications in machines and components
                         Starting from the rigorous testing of the wire for all necessary parameters, balls are produced in specially designed machines called Headder, Flasher and Lapper. Apart from intermediate vigil at all operations, for all quality parameters, finished products are also tested with extremely sophisticated equipments to ensure right quality of BALCO Balls.

bronze balls
Bronze balls are made of a high quality alloy created for environments subjected to attack by gasoline, water and other solvents. Bronze offers resistance to corrosion and is an excellent electrical conductor. Bronze is widely used in the electronics industry and in the manufacture of various valves.
Actual bronze balls are rare in the precision ball industry.  Producing them  would require a special quotation.
