3105 aluminum alloy is a typical deep-drawn material. The aluminum content is up to 98%, which can belong to the category of pure aluminum alloy, which is slightly stronger than the 1 series alloy with aluminum content of about 99%. Similarly, 3105 aluminum alloy cannot be strengthened by heat treatment, but its corrosion resistance, formability and welding properties are also excellent. Therefore, 3105 aluminum alloy is commonly used in the manufacture of residential wall panels, mobile homes and rain gear, bottle caps, lamp headstocks, shutters, etc. In addition, it is also used for sheet metal work. However, 3105 aluminum alloy has medium machinability, so lubricating oil treatment is required in all machining operations. And most importantly, 3105 aluminum alloy temper also affects the machinability required for our different applications. For example, the (H) harder temper is better than the 3105 aluminum alloy in the (O) annealed temper. But no matter how tempered the 3105 aluminum alloy is, the forming characteristics of the 3105 aluminum in all conventional processes are very good.
