Aluminium alloys (or aluminum alloys; see spelling differences) are alloys in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. About 85% of aluminium is used for wrought products, for example rolled plate, foils and extrusions. Cast aluminium alloys yield cost-effective products due to the low melting point, although they generally have lower tensile strengths than wrought alloys.
The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4.0–13%) contribute to give good casting characteristics. Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required.
5000 Series aluminum alloy covers 5052,5005, 5A05, 5754, 5083, 5154, 5182, 5252, 5254, 5356, 5454, 5456, 5457, 5652, 5657, 5A02, 5A03, 5A06, 5A12, 5000 series aluminum alloy belongs to the most common use aluminum alloy, Al percentage of from 3-5%, because of this it get a name Al-Mag Alloy. 5000 Series aluminum alloy is with good performance on low density, high-level tensile strength, elastic, anti-fatigue. 5000 series aluminum alloy is the lightest material in aluminum series. China has the most competitive 5000 aluminum products.
