Brass Hydraulic Fittings are generally made from high-quality brass alloys, primarily consisting of copper and zinc, with carefully controlled amounts of lead or other elements to enhance machinability. This specific composition provides outstanding corrosion resistance, particularly against water, oils, and mild chemicals. On the mechanical side, brass fittings boast good tensile strength, ductility, and impact resistance, enabling them to handle moderate to high hydraulic pressures. They also feature low friction, impressive wear resistance, and stable performance across a wide temperature range, ensuring reliable sealing and a long operational life in hydraulic systems.
