1. 6061 Aluminum Alloy Elements

The main alloying elements of 6061 aluminum alloy are magnesium and silicon, forming the Mg2Si phase. If a certain amount of manganese and chromium is present, it can neutralize the negative effects of iron; occasionally, small amounts of copper or zinc are also added to enhance the alloy’s strength without significantly reducing its corrosion resistance. There is also a small amount of copper in the conductive material to offset the adverse effects of titanium and iron on electrical conductivity. Zirconium or titanium helps refine the grains and control recrystallization structure. To improve machinability, lead and bismuth can be added. The Mg2Si phase dissolves in aluminum, giving the alloy the ability to undergo artificial aging hardening. The main alloying elements in 6061 aluminum alloy are magnesium and silicon, offering moderate strength, good corrosion resistance, weldability, and favorable oxidation properties.

Aluminum alloy basic state code:

F Free Processing State: Suitable for products that require special processing hardening and heat treatment conditions during molding; mechanical properties of these products are not specified (uncommon)

O Annealing status applies to processed products that achieve the lowest strength after complete annealing (occasionally).

H Work hardening state is applicable to products whose strength is enhanced through work hardening. After work hardening, the product may or may not undergo additional heat treatment that reduces strength (typically for non-heat treatment strengthened materials).

W Solid solution heat treatment state – an unstable condition, applicable only to alloys that have undergone solid solution heat treatment and undergo natural aging at room temperature. This state code merely indicates that the product is in the natural aging phase (not common).

T Heat treatment condition (different from F, O, H conditions) applies to products that have undergone heat treatment and have reached stability either through or without processing hardening. After the T code, one or more Arabic digits must be included (typically for heat-treated strengthened materials). The condition codes for common non-heat treated strengthened aluminum alloys usually consist of the letter H followed by two digits.

As per 1100 H14. Below is a brief introduction to the meaning of these status codes.

Generally, two digits follow the letter H: the first digit indicates the hardening treatment method. The first digit after H can be: 1, 2, 3, 4

i.e., H1* H1* indicates a simple work hardening treatment

H2* H2* indicates work hardening and incomplete annealing

H3* H3* indicates work hardening and stabilization treatment

H4* H4* indicates work hardening and painting treatment

The second digit indicates the degree of hardening achieved by the material.

The second digit after H is: 1, 2, 3, 4, 5, 6, 7, 8, 9

Hardness between H*1 0 and 2

H*2 1/4 hard

Hardness between H*3 2 and 4

H*4 1/2 hard; hardness between H*5 4 and 6

H*6 3/4 hardness; H*7 hardness between 6 and 8
