1000 to 8000 series aluminum have different ingredients also have different properties

1100 aluminum coil

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

Aluminum Association Alloy Designation System

● 1st digit – Identifies alloy types.

● 2nd digit – Identifies alloy modifications. Digit replaces letters formerly used.

● 3rd and 4th digits – Identifies the aluminum purity of the specific aluminum alloy.

● The digits are the same as the numbers in the old designations for alloys in use prior to the adoption of the four-digit system.

Temper Designations H-Tempers: Strain-Hardened

● H1 – strain-hardened only.

● H2 – strain-hardened and partially annealed.

● H3 – strain-hardened and stabilized by low-temperature thermal treatment.

● The digit following H1, H2, or H3 indicates the temper:

● 2 1/4Hard

● 4 1/2 Hard

● 6 3/4 Hard

● 8 Full Hard

● 9 Extra Hard
