Aluminum Casting Alloys
The most versatile alloy that’s available from common foundries is aluminum casting alloys. Generally, with this aluminum casting alloys high quality cast products could be produced. It has high fluidity that enables it to disperse into extremely thin gaps. It also has a very low melting point when compared with other metals. It also provides a rapid heating process that enables molten aluminum pieces to fit with the mold very fast thereby helping the casting to take place within a small amount of time.
Green and dry sand, plaster casting, mold, pressure-die and investment produce aluminum alloy castings. It is easy to produce aluminum casting alloys by enforcing low-pressure, and using pattern-related procedures, centrifugal and vacuum. The percentage of impurities and alloying elements should be controlled properly when producing castings alloys. Otherwise, its qualities such as corrosion-resistance, machinability, soundness and conductivity would be subjected to drastic reduction.
With many alloys including aluminum casting alloys when subjected to proper chemical, heat-treatment, and manufacturing process, it is possible to produce high-quality valuable mechanical properties. There are more than 60 alloys used for casting in the manufacturing field today. The high number of alloys makes selection of them for treatment of different casting conditions an extremely grim experience. Such inadequacies put many commercial entities in a position to get recommendation from foundries to select the most suitable and economical alloys for their productions.
On the other hand, designers in commercial respects must infuse their knowledge in the field to find suitable alloys to produce the necessary properties and then should be advised by foundries to make the final choices for their industries. Most often, the alloy that is confirmed as the most suitable one over other alloys on the draft might not be suitable at the practical level, as it may have adverse characteristic properties. The foundries are the most suitable advocatory entities to grant result-oriented consultation in such situation providing information related to availability, ingot costs, production costs, recycling, to produce distinct results.
The USA numbers aluminum casting alloys in accordance with a three-digit and a decimal method introduced by the Aluminum Association in 1954. American National Standards Institute approved the said standard in 1957. Furthermore, the Society of Automotive Engineers, the Federal and Military specifications and the American Society for Testing and Materials also approved this method. Aluminum Casting Alloys are inherent with greater castability, Machinability, weldability, corrosion resistance and finishing than other alloys. Therefore, it is used in the production of high quality products worldwide.
