Leaded Brasses:
Used for their high machinability and atmospheric corrosion resistance. The machinability of brass is increased by the addition of lead because it acts as a microscopic chip breaker and tool lubricant. The leaded brasses are used for copper base screw machine material. The alloys have excellent machinability, good strength and corrosion resistance. Lead can be added to any brass to increase machinability and provide pressure tightness by sealing the shrinkage pores. There are low, medium and high leaded brasses, with lead contents up to 3.5%. The lead brasses are used for architectural hardware, general purpose screw machine parts, screws, valves, fittings, bearings and specialty fasteners.
Tin Brass:
Used for its increased corrosion resistance and somewhat higher strength than straight brass. This family of alloys is made with zinc contents ranging form 2 to 40% zinc, and 0.2 to 3.0% tin. Tin reduces susceptibility of the high zinc brass to dezincification. Dezincification is the selective leaching of zinc from the brass leaving a porous copper structure.
