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.
