The most common aluminium grades available as sheet metal are 1XXX, 3XXX, 5XXX series.
1XXX series is commercially pure aluminium, so it is highly chemical and weather resistant. It is ductile enough for deep drawing and weldable, but low strength. It is commonly used in chemical processing equipment, light reflectors, and jewelry.
3XXX series is stronger than 1100, while maintaining the same formability and low cost.
It is corrosion resistant and weldable, It is often used in stampings, spun and drawn parts,
Mail boxes, cabinets, tanks, reflectors and fan blades.
5XXX series is much stronger than 3003 while still maintaining good formability. It maintains high corrosion resistance and weldability, common applications include electronic classis, tanks, and pressure vessels.
