It can be welded using any method but it is non heat treatable.
Aluminium sheet grade 1100.
Aluminium alloy 1100 is known for its excellent corrosion resistance high ductility and highly reflective finish.
Machinability is poor and tends to be gummy.
Aluminum sheet plate 1100 is normally used for chemical food and beverage ornamental and thermal applications.
This grade is commercially pure aluminum.
High mechanical strength and easy machinability are the features of this grade.
For example if weldability is most important to your project but strength is not it may make sense to choose alloy 1100 as this aluminum grade has excellent weldability but is not typically used for high strength or high pressure applications.
It is soft and ductile and has excellent workability making it ideal for applications with difficult forming.

They have a very high 98 of their average alloy composition in common.
Aluminium alloy aa 1100 is a popular grade of aluminium for general purpose sheet metal works where moderate strength is the requirement.
1100 has excellent welding characteristics.
It is unmatched by any other commercial aluminum alloy in workability.
For each property being compared the top bar is 1100 aluminum and the bottom bar is 6061 aluminum.
It is also soft and ductile so is ideal for applications that require intricate forming as it work hardens slower than other alloys.
Readily to welding brazing and soldering.
1100 aluminum sheet low strength aluminum alloy has excellent corrosion resistance and satisfactory anodizing and conversion coating finishing characteristics.
Aa 1100 is also known for its excellent corrosion resistance high ductility and reflective finish.
Aluminum 1100 is a commercially pure aluminum.
It has an excellent resistance to corrosion and is commonly used in the chemical and food processing industries.
General sheet metal works.
Aluminium alloy 1100 is a popular grade of aluminium for general sheet metal work where moderate strength is required.
Weldability general sheet metal works.
1100 is known for superior corrosion resistance high formability conductivity and weldability.
Al 1100 is noted for having the highest thermal conductivity of any aluminum and is also known for its high electrical conductivity.
1100 is however non heat treatable.
Both 1100 aluminum and 6061 aluminum are aluminum alloys.
