The size and concentration of lead particles depends upon the concentration of lead in the alloy. Leaded 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 making these alloys easier to machine than their non leaded counter parts.
