What is red brass?

Red brass, also known as gunmetal, is a type of brass alloy that is composed of approximately 85% copper, 5% tin, 5% lead, and 5% zinc. It has a reddish-brown color and is commonly used for plumbing fittings, valves, pump components, and other applications where corrosion resistance, durability, and machinability are important. Red brass is also known for its excellent thermal and electrical conductivity, making it a popular choice for electrical connectors and components. It is often used in marine environments due to its resistance to saltwater corrosion. Additionally, red brass can be easily soldered and brazed, making it a versatile material for a wide range of applications.
