Brass Hydraulic Fittings are mainly made up of copper, which accounts for about 60–70%, and zinc, making up around 30–40%. Sometimes, small amounts of lead, tin, or nickel are added to improve their machinability and resistance to corrosion. These fittings are known for their impressive tensile strength, usually falling between 350–550 MPa, and they also boast good yield strength and excellent elongation properties. Brass is great for thermal and electrical conductivity, offers remarkable ductility, and shows strong resistance to dezincification and stress cracking. This alloy stays mechanically stable even under different pressures and temperatures, ensuring that it performs reliably without leaks in hydraulic and pneumatic systems.
