1. Aluminum alloys generally have lower strength, hardness and wear resistance than steel. Therefore, they are not suitable for components under heavy loads and severe wear, such as gears and shafts.

      2. Aluminum alloys are ideal for metal structural parts, enclosures of machinery and instruments, various containers, and skins of moving machinery. They are especially recommended for components with weight constraints.

      3. Wrought aluminum alloys feature excellent ductility. They can be extruded into structural parts with intricate cross-sections, thin walls and high dimensional accuracy.
