This results in a more uniform grain structure which limits tearing and is referred to as "draw high quality" material. During the rolling process the rollers bow barely, which results in|which leads to|which ends up in} the sheets Luggage Sets being thinner on the edges. Grade 1100-H14 is commercially pure aluminium, extremely chemical and weather resistant. It is ductile sufficient for deep drawing and weldable, but has low energy. It is often used in chemical processing equipment, light reflectors, and jewelry.
