|The following is a short breakdown of the most common grades and their general properties in order to provide you with an understanding of their many uses:
|Aluminum 1100: Aluminum of 99 percent or higher purity has many applications, especially in the electrical and chemical fields. These compositions are characterized by excellent corrosion resistance, high thermal and electrical conductivity, low mechanical properties and excellent workability characterize these compositions. Moderate increases in strength may be obtained by stain-hardening. Iron and silicon are the major impurities.
|Aluminum 2011: High mechanical strength and easy machinability are the features of this grade. It is the most free-machining aluminum grade, widely used for automatic screw machine products requiring extensive machine work. Fine chips equal faster feeds and long tool life. Its corrosion resistance is good and it may be resistance welded. It machines to an excellent finish.
|Aluminum 2024: Copper is the principal alloying element in this group. These alloys require solution heat-treatment to obtain optimum properties; in the heat-treated condition mechanical properties are similar to, and sometimes exceed, those of mild steel. In some instances artificial aging is employed to further increase the mechanical properties. This treatment materially increases yield strength, with attendant loss in elongation; its effect on tensile (ultimate) strength is not as great. The alloys in the 2000 series do not have as good corrosion resistance as most other aluminum alloys and under certain conditions they may be subject to intergranular corrosion. Therefore, these alloys in the form of sheet are usually clad with a high-purity alloy or a magnesium-silicon alloy of the 6000 series, which provides galvanic protection to the core material and thus greatly increases resistance to corrosion. Alloy 2024 is perhaps the best known and most widely used aircraft alloy.
|Aluminum 3003: Manganese is the major alloying element of alloys in this group, which are generally non-heat-treatable. Because only a limited percentage of manganese, up to about 1.5 percent, can be effectively added to aluminum, it is used as a major element in only a few instances.Excellent workability rating. May show some slight discoloration when anodized, but reacts well to mechanical and organic finishings. Is easily welded and brazed, but soldering is limited to the torch method. Added manganese increases tensile strength. Used for drawing, spinning, fuel tanks and sheet metal work. This alloy is non-heat treatable, and is corrosion resistant.
|Aluminum 5005: Magnesium is one of the most effective and widely used alloying elements for aluminum. When it is used as the major alloying element or with manganese, the result is a moderate to high strength non-heat-treatable alloy. Magnesium is considerably more effective than manganese as a hardener, about 0.8 percent magnesium being equal to 1.25 percent manganese, and it can be added in considerably higher quantities. Alloys in this series posses good welding characteristics and good resistance to corrosion in marine atmosphere. However, certain limitations should be placed on the amount of cold work and the safe operating temperatures permissible for the higher magnesium content alloys (over about 3 ½ percent for operating temperatures above about 150 degrees F) to avoid susceptibility to stress corrosion.Typical end uses are decorative trim, utensils, mobile home siding and reflectors.
|Aluminum 5083: With excellent corrosion-resistance and weldability, together with high strength, this alloy was designed for welded structures requiring maximum joint strength and efficiency.
|Aluminum 5086: Has excellent corrosion-resistance and weldability. Can be anodized for increased corrosion-resistance,Typical end uses are marine craft, containers, railroad cars, structurals and elevator cars.
|Aluminum 6061: Alloys in this group contain silicon and magnesium in approximate proportions to form magnesium silicide, thus making them heat-treatable. Major alloy in this series is 6061, one of the most versatile of the heat-treatable alloys. Though less strong than most of the 2000 or 7000 alloys, the magnesium-silicon (or magnesium-silicide) alloys possess good formability and corrosion resistance, with medium strength. Alloys in this heat-treatable group may be formed in the T4 temper (solution heat-treated but not artificially aged) and then reach full T6 properties by artificial aging.Very good corrosion-resistance and finishability plus excellent weldability and a strength level approximating that of mild steel, this is a popular general-purpose alloy.
|Aluminum 6063: Commonly referred to as the architectural alloy. It was developed as an extrusion alloy with relatively high tensile properties, excellent finishing capabilities, and corrosion resistance. Often used in various exterior and interior architectural applications, such as windows, doors, store fronts, and trim. It is also well-suited for anodizing.
|Aluminum 7075: This is one of the highest strength aluminum alloys available. It is ideally used in highly stressed parts. In sheet, it is also available as Alclad to improve corrosion resistance. Often used in aerospace applications because of its desirable mechanical properties. May be formed in the annealed condition and then heat-treated.
