7005 has excellent weldability under all standard methods, including GMAW (MIG) and GTAW (TIG). Filler alloy 4043 is the main filler material, but 5356 welding wire is recommended as an alternative.
The most typical characteristic is weldability. There are many other aluminum alloys, such as 7075 and 2014, which are stronger than 6061 and 7005, but are almost impossible to weld.

7005 T6 aluminum plates are widely used in high-strength components such as aircraft seats and cargo compartment panels. They offer excellent mechanical properties and high corrosion resistance, making them suitable for withstanding the various stresses experienced during flight.
7005 T6351 aluminum plates, through specific processing techniques, can reduce internal stresses and enhance material stability. This treatment allows the aluminum plate to maintain high strength even when cut into smaller pieces, making it commonly used for manufacturing fixtures and precision components. The high strength and stability of 7005 T6351 aluminum plates make them outstanding in machining and precision manufacturing.
