7075 Aluminum

Maximum structural strength

7075-T651 aluminum is an aluminum-zinc-magnesium-copper alloy with very high mechanical strength. It stands out for its excellent strength-to-weight ratio, good machinability and ability to withstand high loads, although it has lower weldability and corrosion resistance than 6000-series alloys.
