Milward Alloys, Inc.

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 alloys Nuclear shielding alloys Ultra-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

ACU-STIX™ Extruded Rod - 0.890" (22.5 mm) 2-oz. (50 g) pieces - approx. 2" (5 cm) 4-oz. (100 g) pieces - approx. 4" (10 cm) 6-oz. (150 g) pieces - approx. 6" (15 cm) 8-oz. (200 g) pieces - approx. 8" (20 cm) ACU-STIX are accurately measured and supplied in exact lengths (e.g. 1" = 1 oz.), enabling you to make precise additions. They are available in 2 - 8 oz. pieces and other sizes on request. All shapes are designed to have the same cross-sectional area. Alloys are identified by different shapes. ACU-STIX are superior to chopped rod in batching foundry applications because they are more convenient. One piece provides the exact weight addition you need. ACU-STIX are superior to buttons because their unit weight is more precise and accurate, and they can be supplied in made-to-order units with tight tolerances. ACU-STIX are cleaner (free of oxide) than buttons and compatible in price.

ACU-COIL™ Extruded Rod - 38" (9.5 mm) 400-lb. coils (180 kg) 600-lb. coils (275 kg) 1000-lb coils (450 kg) A variety of Milward's aluminum master alloys are available. ACU-COIL coiled rod is supplied in 400, 600 and 1, 000 lb. coils. In addition to ACU-STIX, ACU-BAR, and ACU-COIL, Milward supplies Cut Extruded Rod in its Precision Addition line of products. Cut Extruded Rod - 38" (9.5 mm) 1-oz. (30 g) pieces - approx. 6" (15 cm) 6.5-oz. (200 g) pieces - approx. 40" (1 m)

• Aluminum Waffle Ingot- 16 lbs. (7 kg)
• Aluminum Notch-bar Ingot- 15 lbs. (7 kg) and 50 lbs. (22 kg)
• Aluminum Cut Waffle- 1 lb. (0.5 kg)

Applications: Grain Refiners Grain 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. Modifiers Usually 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. Hardeners Hardener chemical elements change the composition of metal alloys. Beryllium-Aluminum These 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.
