7 series aluminum alloy is another popular variety. It contains zinc and magnesium. More common in strength aluminum alloy 7075 is the best , but it can not be welded , and its corrosion resistance is quite poor, a lot of manufactured parts using CNC machining is 7075 alloy . Zinc is the major alloying elements in this series, with a little magnesium alloy material can be affected by heat treatment can reach very high strength characteristics. This series of materials is generally a small amount of copper, chromium and other alloys, and which numbers especially the top grade 7075 aluminum alloy , the highest intensity for aircraft structures and high strength parts .

Si Si: 0.40
7075 aluminum rod processing characteristics
7075 is known as ultra high strength aluminum alloy, the alloy is close to the yield strength and tensile strength , yield ratio , is also high strength, ductility and high temperature strength than the end , should be done at room temperature , the load-bearing structure using the following 120 ℃ parts, alloy ease of processing , there is the same good corrosion resistance and high toughness . The alloy is widely used in aviation and aerospace , and this area became one of the most important structural materials.

7075 aluminum bar
7 series aluminum alloys are Al-Zn-Mg-Cu based hard aluminum alloy in the late 1940s had been used in the aircraft industry , the aviation industry is still widely used to get ultra-high -strength wrought aluminum alloys. Its characteristics are good plasticity after solution treatment , heat strengthened particularly effective at below 150 ℃ high strength , and has a particularly good low temperature strength ; poor weldability ; has a tendency to stress corrosion cracking ; subject clad aluminum or other protection processing.
