  • 7075 aluminum is one of the strongest aluminum alloy, and it is almost as strong as some low-grade steels, but with an obvious ligher weight. So 7075 aluminum extrusions provide stronger and more durable properties in use.
  • 7075 aluminum extrusion has high strength, excellent mechanical properties, and anode reaction.
  • 7075 aluminum extrusions are mainly used to manufacture aircraft structures and other high-stress structural parts that require high strength and high corrosion resistance, such as upper and lower wing panels and purlins. And 7075 aluminum extrusions are also widely used in mold processing, mechanical equipment, fixtures, and so on.
  • The excellent durability, great corrosion resistance, and high strength of 7075 aluminum extrusions make it an ideal option for some challenging use, like marine, aerospace, automotive, ski poles, bike frames, climbing equipment, etc.

7075T6 aluminum extrusion-fonnovaluminium.com

7075 aluminum alloy is super hard, but it can still be extruded. 7075T6 is common extrusion products. 7075 T6 aluminum has good plasticity after solution treatment and has excellent heat treatment strengthening effect. It has high strength below 150 degrees and has particularly useful low-temperature strength, poor weldability, stress corrosion cracking tendency, and double aging can improve anti-SCC performance. It has lower resistance to corrosion than many other aluminum alloys but has significantly better corrosion resistance than the 2xxx (2024, 2A12) alloys. Its relatively high cost limits its use, and its extrusion is also harder in production compared with other aluminium alloys.
