The A 1050 series aluminum  are the purest forms of aluminium    resistant to chemical attack and weathering, easily worked and welded, but have the lowest strength of the aliminium grades.A1050 aluminum products are often used in chemical processing equipment and other applications where material purity is important. A1050 series aluminium is highly ductile and is used for metal pressings of all types.  

Aluminium 1050 sheet  also know as A1050  H14 Sheet it is a common and well know grade of aluminium for general purpose sheet and plate metal work. Especially for the purpose of where medium strength is required.
The aluminium alloy (1050) is known for its high corrosion resistance, ductility and reflective finish and are widely .

Applications – Alloy 1050 is typically used for:
Chemical process plant equipment and machines,food industry containers and storage,pyrotechnic powder,architectural flashings,lamp reflectors,cable sheathing
