Leaded Copper

Lead is added to many copper alloys to make all types of free machining alloys. Lead does not affect the structure and properties of copper because it is practically insoluble in solid copper. Lead coppers are categorized as low lead alloys, or free-machining alloys and high lead alloys. In the free-machining alloys, the lead acts as chip breaker and lubricant which makes these alloys easier to machine than their non-leaded counter parts. High lead copper alloys are used in bearing applications.
