1100-H14 aluminum is usually what is meant by â€œcommercial grade aluminum.â€ It is known for its superior corrosion resistance, formability, conductivity, and high weldability. It is not used in applications that require high strength or hardness. 1100 is nonmagmetic, weldable, and not heat treatable.
1100 is typically used for chemical equipment, food handling equipment, decorative trim, lighting equipment, and heat exchangers. If excellent malleability and corrosion resistance are your primary goals, 1100-H14 is an excellent choice.
