Aluminium 1050
Scope
Aluminium 1050 is a popular grade of aluminium for general sheet metal work where moderate strength is required. Alloy 1050 is known for its excellent corrosion resistance, high ductility and highly reflective finish.
Application
This material is used for chemical process plant equipment, pyrotechnic powder, lamp reflectors, food industry containers, cable sheathing and architectural flashings.
Supplied Forms

Alloy Designations
Aluminium alloy 1050 also corresponds to: AA1050A, S1B and A91050.
Temper Types
The most common tempers for 1050 aluminium are: H14 - Work hardened by rolling to half hard, not annealed after rolling.
Fabrication
