Nickel ball

tungsten carbide

These balls share almost the same characteristics as our Cobalt Bound Tungsten Carbide (hardness, dimensional stability, high resistance to wear and tear) but with one significant difference - they offer significantly improved resistance to corrosion and abrasion. Benefits In tests we've found that our Nickel bound Tungsten Carbide balls are resistant to corrosion right down to pH 2 or pH 3 (which is where you'll find lemon juice and vinegar on the scale). This makes them highly suitable for use in environments where conditions are corrosive and abrasive. Use You'll find these balls used widely in valves and pumps of various kinds and in environments where the chemical content is likely to be higher or more aggressive.
