Copper Balls exhibit good corrosion resistance in environments where fuel oil, gasoline, kerosene, and alcohol are present. Copper balls provide excellent resistance to corrosion by water. Copper also exhibits excellent electrical conductivity and widely used in the security and appliance industries for dip and tilt switches. Copper balls are available in a range of sizes, tolerances and grades of copper. Copper balls can come in useful in devices when electrical conductivity is needed. Copper balls are also much cheaper than ceramic balls but both have their own unique properties that make them useful for specific tasks.
