For producers of primary and secondary aluminium alloys, alloy wheel makers. Aluminium Casting Alloys For producers of automotive castings (cylinder heads & blocks, wheels, brake calipers), aerospace castings, lost wax investment castings, pressure die castings. Aluminium Alloys UK Investment CastingAluminium Alloys:Investment Casting Materials . Aluminium Alloys have a distinct advantage over ferrous and copper base alloys - their lower density. This attribute is the primary reason that Aluminium is selected as a cast alloy. For more information, please see table Aluminium Alloy
Nov 23, 2015 · An overview is given of grain refinement in aluminum casting alloys. The mechanisms involved and the benefits of refinement are described. The review shows that current practices were developed long before modern Al-Ti-B refiners became available, and are employed now largely for historical reasons. The results of tests in Al-Si, Al-Si-Cu, Al-Cu, Al-Mg and Al-Zn-Mg alloys are Modification and Refinement of Aluminum-Silicon Alloys
- Chemical ModifierRefinement of Hypereutectic Aluminum-Silicon AlloysMetal PreparationThere is, however, no agreement on the mechanisms involved. The most popular explanations suggest that modifying additions suppress the growth of silicon crystals within the eutectic, providing a finer distribution of lamellae relative to the growth of the eutectic. The results of modification by strontium, sodium, and calcium are similar. Sodium has been shown to be the superior modifier, followed by strontium and calcium, respectively. Each of these elements is mutually compatible so that combinationFoundry alloys - HydroProduct details. Alloys are produced as continuous cast or mold cast ingots. The products are stacked and strapped into bundles of various sizes. Depending on the particular production source, our foundry alloy ingots are supplied in weights of 7-22 kg, and bundle weights can range from 700-1200 kg. Frequently used alloy groups:AlSi7Mg alloys.

Primary casting aluminum alloys made from primary aluminum, usually, ingots or bars, which is remelted with the addition of alloying elements necessary for a given alloy. Secondary cast aluminum alloys made (cheaper, than primary) from aluminum scrap, which, after careful sorting, is remelted with the addition of the necessary alloying elements. Iron in secondary aluminum. Secondary alloys have a Products Cast alloys and products - European AluminiumAluminium Foundry Alloys can be tailored to cover a wide range of mechanical performance via chemistry and/or process control. There are four main families based on RaffmetalAluminium Alloys in continuous casting. 01 A high-quality product. Since 1994 Raffmetal succeedes with a 100% continuous casting production. This innovative technology guarantees users a wide range of advantages compared to standard ingots.
Semi-solid processing of the primary aluminium die casting alloy A365. Yucel Birol. IntroductionAl-Si-Mg alloys are the material of choice for many automotive castings . The main production process is high pressure die casting and the predominant alloy is A365 (AlSi9MgMn) because of its outstanding mechanical properties and good welding Terms and Definitions - Aluminum2.2.5. casting alloy alloy primarily intended for the production of castings 2.2.6. refined aluminium alloy casting alloy obtained after metallurgical treatment of molten metal obtained from aluminium scrap 2.2.7. wrought alloy alloy primarily intended for the production of wrought products by hot and/or cold working 2.2.8. heat-treatable alloyPrimary Aluminium Casting Alloys - Foundry-planetsent minimum values for castings with wall thicknesses up to 20 mm.
