15% Phosphor Copper – recognized for its quality and performance in deoxidizing alloys, increasing fluidity, and inhibiting gas porosity.

8% Phosphor Copper – used primarily in the production of 390 alloy aluminum as a grain refiner to enhance strength, wear resistance, and machinability of this aluminum-silicon casting alloy.


Choice of Forms and Packaging

  • Both 15% and 8% phosphor copper are available in either shot or waffle form.
  • Shot is 3/8 inch / 10.0 mm diameter and smaller, or can be specially sized to meet specific application needs. Shot can also be packaged in pre-weighed packets of 2oz., 3 oz., 4 oz., and 6 oz.
  • Waffle is rectangular and weighs approximately 15 lbs. / 7 kg. Due to its brittleness, 15% phosphor copper waffle is easily broken into smaller pieces.
