7075 aluminum rod
7075 is a cold forging alloy , high strength, far better than mild steel . 7075 is one of the most hard commercial alloys . General corrosion resistance, good mechanical properties and the anode reaction . Fine grain makes better deep drilling , tool wear , thread rolling and differentiated .
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 .
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.

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.
