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.

(a) Our pure copper ball are noted for their corrosion resistance and their excellent ability to conduct both heat and electricity
(b) While their conductivity makes them ideal for electrical applications, their corrosion resistance suits them to use in marine environments and industrial settings where halogens, salts, sulphides, and water are present
(a) 99% Pure Copper Ball mainly used in kinds of electric accessories,switch,carburetor
(b) The ball is soft so it is easy to be drilled,then usually used in valve , fuel injectors, sprayers,pressure gauges,water meter ,transmission system,jewelly,bracelet,earrings, necklaces, touch-spot and art ware
