Brass rods are used in mechanical manufacturing and the automotive industry

In the field of mechanical manufacturing, brass rods are ideal materials for making wear-resistant components such as gears, bearings, and valves. For instance, the thermostat valve of a car engine is made of H65 brass (65% copper and 35% zinc). Its high-temperature resistance (operating temperature ≤150℃) and oil corrosion resistance ensure the stable operation of the engine cooling system. In CNC machine tools, the brass guide rail sliders, after surface hardening treatment, can withstand high-frequency friction without deformation, and their service life is increased by more than 30% compared with aluminum alloy components.
