The main alloying elements of 66061-T6 are magnesium and silicon, which have medium strength, good corrosion resistance, weldability and good oxidation effect. It is widely used in various industrial structural parts that require a certain strength (85-110 degrees) and high corrosion resistance, such as the manufacture of trucks, tower buildings, ships, trams, railway vehicles, furniture machinery parts, precision machining, molds, etc.

6061-T6 chemical composition

Cu: 0.15-0.4 Si: 0.4-0.8 Fe: 0.7 Mn: 0.15 Mg: 0.8-1.2 Zn: 0.25-0.50 Cr: 0.04-0.35 Ti: 0.15

They are four-digit aluminum alloys with magnesium and silicon as the main alloying elements and Mg2Si phase as the strengthening phase.

6061-T6 alloy state

T6 is the state of artificial aging after solution heat treatment. It is suitable for products that are not subjected to cold processing after solution heat treatment (straightening and leveling can be carried out, but the mechanical performance limit is not affected).
