Abstract
A method of producing a brass is disclosed. The alloy contains trace amounts of iron, manganese or aluminum. Phosphorous is added to a zinc, copper melt and combined with the iron, manganese and aluminum to form intermetallics. Additional phosphorous is added so the melt contains between about 0.08 to 0.15% phosphorous. A low lead brass alloy is provided. The alloy has tin in the range of 0.15% to 0.35%.
