Metallic alloy balls such as brass balls and bronze balls exhibit excellent corrosion resistance to chemicals, water, gas and oil. Brass balls are used in measurement devices, flow meters, pumps and valves. Brass balls are also ideal for electrical conductivity, electrical appliances and electrical contacts. Due to the low friction properties of brass balls gasoline rollover valves and fire equipment hose couplings are also common applications.
Brass balls are very hard, very salt water stable, water resistant. Due to its unique properties, which include corrosion resistance, common uses for Brass include applications which require low friction. These applications can include fittings (fasteners and connectors), tools, appliance parts, and ammunition components. It is good for electroplating and any electrical conductivity requirements. The metal has both good heat and electrical conductivity (its electrical conductivity can be from 23% to 44% that of pure copper), and it is wear and spark resistant (energy exploration).
