Aluminum Linear Rail

Product Description

7075 aluminium alloy is a cold treated wrought alloy with high strength, far superior to soft steel. 7075 is one of the most powerful alloys commercially available. General corrosion resistance, good mechanical properties and anodic reaction. The fine grain size allows for better depth drilling performance, increased tool wear resistance and thread rolling with a difference. Zinc is the main alloying element in 7075 and the addition of magnesium to an alloy containing 3% to 7.5% zinc results in the formation of MgZn2, which has a significant strengthening effect and makes the alloy far superior to aluminium-zinc binary alloys in terms of heat treatment. By increasing the zinc and magnesium content of the alloy, the tensile strength is further improved, but its resistance to stress corrosion and spalling corrosion is subsequently reduced. The 7075 material is generally alloyed with a small amount of copper and chromium, and the 7075-T651 aluminium alloy is particularly good, being the best of the aluminium alloys, with high strength and far superior to any soft steel. This alloy also has good mechanical properties and anodic reaction. Typical applications include aerospace, mould processing, mechanical equipment, jigs and fixtures, especially for aircraft structures and other highly stressed structures requiring high strength and corrosion resistance.
