Copper Alloy Products & Services
Major uses of phosphorous-copper for manufacturers in
the copper industry are (1) as deoxidants, (2) alloying agents and (3)
wetting agents.
1. As a deoxidant to remove oxygen from copper baths, thereby producing
cleaner product free of metal oxides.
2. As an alloying agent in copper tin alloys and in high performance
electrical conductive alloys. Phosphorous, when added to copper alloys,
increases their strength, hardness and elasticity while reducing creep
and grain growth.
3. As a wetting agent in brazing alloys. Phosphorous, when added to
brazing rods, lowers their melting temperatures and improves their
wetting characteristics, resulting in a cleaner, stronger brazed joint.
The major use of 8% phosphorous-copper in the aluminum industry is as a
nucleant in greater than 11% Silicon-Aluminum. When added to
Silicon-Aluminum, Phosphorus-Copper forms AIP, which causes silicon to
solidify as small, blocky particles instead of long, brittle fingers.
The results are improved toughness, wear-resistance, castability and
machinability. Phosphorous-copper is produced in a
range of alloys and in two primary product forms: (1) shot and (2)
waffle ingot.
Shot, usually packed in closed, sealed drums, 500 to 850 pound (226 –
385 kg) with dessicants to control moisture. Available size ranges from
3/8 to 1/16 inch.
Waffle is produced in ingots size 9" X 15" X 1 1/2" weighing
approximately 50 pounds each.
