Aluminum is best known for its lightweight characteristics. It is most widely used in the form of alloys which also contain varying quantities of other elements such as iron, manganese, magnesium, silicon, copper and zinc. The addition of these elements may enhance the strength of the final product, or contribute useful properties such as improved electrical or thermal conductivity. Aluminum alloys are used to manufacture components for the automotive, power transmission, electronics, computing, telecommunications industries, and more.
Wrought iron and aluminum alloys employ a specialized numerical identification system to describe the composition of wrought iron metal alloys and castings. The first digit represents the general class or series and indicates the primary alloy(s). A capital letter preceding the numerical description refers to modifications made to specific alloys. Aluminum castings end in “.0”.
In commercial specifications, aluminum alloys are usually divided into three categories: pure aluminum alloys, heat treatable alloys and non-heat treatable alloys.
Pure aluminum alloys or the 1xxx series are comprised of at least 99% pure aluminum. Commonly used for transmission or power grid lines, these products display excellent corrosion resistance, workability and light weight.
Some types of aluminum alloys gain strength after heat treatments followed by quenching or rapid cooling. These metals typically fall within the 2xxx series (containing significant copper), 6xxx series (containing compounds of magnesium silicide) and 7xxx series (containing significant amounts zinc). A few 4xxx series alloys also do permit heat treatment, although the majority remain non-heat treatable.
Non-heat treatable alloys generally require cold working, such as rolling or forging. Examples of alloys in this category include alloys in the 1xxx series (containing pure aluminum), 3xxx series (containing manganese), 4xxx series (containing silicon) and 5xxx series (containing magnesium).
Aluminum casting remains the oldest, best-known way to form high quality precision parts inexpensively. It involves pouring molten metal into a mold to reproduce a desired form. Depending upon the composition of the alloys employed, metal parts manufactured in this way display several desirable properties. Features may include lightweight, high temperatures resistance, corrosion resistance, electrical conductivity, strength and good finishing characteristics.
Bunty LLC offers four different types of aluminum casting processes. The selection of aluminum alloys typically depends upon the availability and cost of a particular alloy, the comparative complexity of the casting design, and the customer’s preferred casting process. We perform the following casting processes in our facilities:
A versatile, inexpensive, comparatively slow process, this casting process reproduces ornate surface designs accurately. It enables the casting of any size of part, including large parts. Available for A356.0, C355.0, 357.0, 443.0, 520.0 and 713.0 alloys.
Producing superb exterior surfaces that often permit reduced reliance upon secondary finishing, investment casting produces intricate shapes using virtually any alloy. Available for these alloys: 208.0, 295.0, 308.0, 355.0, 356.0, 443.0, 514.0, 535.0, 712.0
We force molten metal into a steel die under pressure during this casting process. It suits high volume production methods in which parts require minimal machining and finishing. Available for these alloys: A380.0, 360.0, 380.0, 413.0, 518.0
We use this casting method in conjunction with cores of steel (or other metals) and molds to create stronger parts than we could produce using sand casting or die casting processes. Available for A356.0, A357.0, B443.0, C355.0,355.0,356.0, 366.0, and 513.0 alloys.
