● 1000's - Aluminum 99% min. - excellent corrosion resistance, high thermal and electrical conductivity, low mechanical properties
● 2000's - Copper - high mechanical properties, increased yield strength, best known and most widely used aircraft alloy
● 3000's - Manganese - good workability and weldability, high corrosion resistance, moderate strength
● 4000's - Silicon - low melting point, widely used in welding wire and as a brazing alloy

●5000's - Magnesium - moderate to high strength, good welding characteristics, good resistance to corrosion, especially in marine environments

●6000's - Magnesium/Silicon - good formability and corrosion resistance, moderate strength
● 7000's - Zinc - highest strength alloy available, used in air-frame structures and for highly stressed parts 8000's - Other element
