Bronze Balls

 

Much like brass balls, Aluminum Bronze Balls provide excellent service in resisting corrosion in water.  Cost is moderate in comparison with other types of large-diameter, corrosion-resisting balls.

Large size aluminum bronze balls are widely used by manufacturers of valves, spraying machines, pumps and similar equipment. These balls have many of the characteristics and advantages afforded by brass balls, however, they are offered in a range of larger sizes.
