It's commonly used for electrical switches, connectors, and battery caps as well as decorative metal applications. Brass ball stock is often used in ball valves due to its low-friction properties and ability to withstand exposure to water, gas, and oil.

Brass rectangle and square tube stock provides support in industrial and architectural applications. Brass rod stock has superior machinability, thread rolling, and knurling properties.
