Iron & Metal Alloys #5143698

Phosphorus-Copper is an alloy of elemental copper and elemental phosphorus free of residuals, such as iron, silicon, arsenic, selenium, nickel, tin, zinc, or lead. It improves the predictability of your process and eliminates the potential for hydrogen embrittlement.Milward offers three grades of Phosphorus-Copper for the copper industry and one grade for the aluminum industry. 15% Phosphorus-Copper for the Copper Industry Grade PS-4412: Brazing rod quality that contains a maximum of 0.020% iron.Grade PS-4415: Mill quality that contains a maximum of 0.035% iron.Grade PS-4420: Commercial grade that contains a maximum of 0.15% iron.8% Phosphorus-Copper for the Aluminum Industry Grade PS-4410: Commercial grade that contains a maximum of 0.15% iron.Applications: Phosphorus-Copper is used as a deoxidant, alloying agent, and wetting agent for the copper industry, and as a nucleant for the aluminum industry. Click on the application listed for details, recommended addition procedures, and precautions.Note: Phosphorus-Copper is also known in the metallurgical industry as phos copper, copper phos, phosphor copper and copper phosphorus.

Custom or Non-standard Alloys for the Metallurgical Industry As an experienced supplier of aluminum- and copper-based alloys and additives, Milward employs its expertise to develop specialized alloys for the proprietary applications of our customers. We offer a full range of services including design, prototyping, testing and production. Finished product, from a few pounds to 1-12 tons, is provided in billets or slabs for industrial-scale production. As required, we will provide Non-Disclosure Agreements (NDA) to ensure full confidentiality. 6" x 18" x 118" (15 cm x 46 cm x 300 cm) Borated Aluminum 4.5% 10B in 1100 Alloy. Weight = 1300 lbs. (590 kg) Sample Applications:Exotic welding alloysNuclear shielding alloysUltra-high purity aluminum for marine and aerospace (e.g. propellers, space shuttle)Automotive parts and components (e.g. motorcycle accessories)Peculiar alloys incorporating curiosity elements (e.g. gallium, indium, scandium)Other highly specialized or engineered master alloys and additives

Applications: Grain RefinersGrain refiners containing titanium (with or without boron) control the structure and dispersion of individual crystals in metals to produce finer grain sized castings. They provide consistent improved mechanical strength and soundness of the casting.ModifiersUsually supplied for use in Silicon-Aluminum alloys, modifiers change micro-structural properties of metal to increase strength, toughness, ductility, and resultant machinability. Milward offers modifier alloys for hypoeutectic Silicon-Aluminum and refiner alloys for hypereutectic Silicon-Aluminum. Strontium is favored where Si concentration is below 12%. Phosphorus-Copper is a highly effective refiner for high Si content alloys such as A390. HardenersHardener chemical elements change the composition of metal alloys. Beryllium-AluminumThese alloys provide effective control of aluminum melt oxidation by forming a tight protective oxide on the liquid surface. Minimization of oxygen pickup has the concurrent benefit of reducing magnesium oxidation loss and inclusion contamination common to high Mg Al alloys.
