7075 refers to a commonly used alloy in the 7-series aluminum alloys. Among the more common aluminum alloys, 7075 alloy offers exceptional strength. It is widely used in CNC-machined parts and is suitable for aircraft frames and high-strength components. 7-series aluminum alloys contain zinc and magnesium. Zinc is the primary alloying element in this series, resulting in excellent corrosion resistance. The addition of a small amount of magnesium allows the material to achieve very high strength after heat treatment. Solution treatment results in excellent plasticity, and heat treatment strengthens it exceptionally well. It exhibits high strength below 150°C and exceptionally good low-temperature strength.

6063 aluminum, primarily composed of magnesium and silicon, offers excellent processing properties, including weldability, extrudability, electroplating properties, good corrosion resistance, and toughness. It is easily polished and color-coated, and exhibits excellent anodizing properties, making it a typical extrusion alloy. It exhibits excellent corrosion resistance, weldability, cold workability, and moderate strength. Due to its numerous advantages, including good plasticity, moderate heat-treatment strength, excellent weldability, and a gorgeous surface color after anodizing, 6063 aluminum alloy is widely used in architectural profiles, irrigation pipes, and tubes, rods, and profiles for vehicles, stands, furniture, elevators, and fences.
