Leaded Brass
Addition of Lead to Brass increases not only the machineability but also its strength and persistence to corrosion. Main purpose of adding lead is to seals shrinkage pores to provide pressure tightness. The classification of Brass can be low, medium or high-leaded based on the lead content which can be as much as 3.5 percent. Brass with lead can be used to make screws, valves, fittings, bearings, specialty fasteners, architectural hardware, and general purpose machine parts.
