Other Materials

Phosphor Bronze Balls

These are fine grained, strong balls made from an alloy of copper, tin and phosphorus.

Benefits

Tough. High corrosion resistance to water, steam, mineral oils and petroleum spirit, good electrical conductivity.

Use

Widely used in electrical apparatus.

Brass Balls

These balls are made from an alloy of 70% copper and 30% zinc; they are fairly ductile and extremely malleable.

Benefits

Good resistance to corrosion by water, fuel oil, gasoline, kerosene and alcohol; very good electrical conductor. Note: unstable in acid and alkalis.

Use

Found in many household electrical appliances.

Glass Balls

We make three different kinds of glass balls - Soda Lime Glass, Borosilicate and Lead Glass.

Benefits

When polished, glass balls provide an excellent seal for check valves; they offer good chemical resistance along with high electrical insulation.

Use

Ideal for check valves in pharmaceutical, food and photographic processing equipment.

Aluminium Balls

These balls are made from aluminium, a soft and ductile metal.

Benefits

They weigh less than steel balls, conduct heat and electricity efficiently and are highly resistant to corrosion (though they have low mechanical strength).

Use

Often found in the stud welding industry where they're used instead of fasteners.

Hastelloy C Balls

These balls are made from a Nickel Chromium Molybdenum Tungsten alloy which offers excellent corrosion resistance, especially against crevice and pitting corrosion.

Benefits

These offer many of the same characteristics as stainless steel balls with one important difference - they remain stable at very high temperatures; up to 1040 C.

Use

You'll find these balls being used in the treatment of waste, marine engineering as well as pulp and paper production.
