What does the T6 mean in aluminum?
What does the T6 mean in aluminum?
Solution heat treated and artificially aged
T6 – Solution heat treated and artificially aged. T7 – Solution heat treated and stabilized (overaged). T8 – Solution heat treated, cold worked and artificially aged. T9 – Solution heat treated, artificially aged and cold worked.
What is a grade aluminum?
Grade 6082 is the most common grade of commercial aluminium sections & plates, whilst T6 is the most common temper. Grade 6063 is a medium strength alloy, it is the most common grade of aluminium for extruding. As far as commercial aluminium sections are concerned, T6 is the most common temper available.
What does the T stand for in aluminum?
The “H” designation means strain hardened, the “O” designates an annealed aluminum alloy, the “T” indicates that the aluminum alloy has undergone thermal treatment, and the “W” designates thermal heat treating.
Does 6061-T6 wrought aluminum?
Generally, 6061 aluminum is solution heat treated, then aged. T4 temper aluminum is naturally aged, and T6 temper aluminum is artificially aged for maximum strength….Mechanical Properties of 6061 Aluminum.
| Property | 6061-T4 | 6061-T6 |
|---|---|---|
| Tensile Strength | 241 MPa | 35000 psi | 310 MPa | 45000 psi |
Are there different grades of Aluminium?
There are also many aluminum grades, mainly due to its properties such as a great strength to weight ratio and corrosion resistance. The grades of aluminum indicate the alloying additives used. These alloys can include copper, silicon, manganese, zinc, or a mixture of these in different ratios.
What is Al 6061 T6 aluminum alloy?
US ASTM AISI and SAE Standards 6061 Aluminum Alloy (Al 6061-T6, 6061-T651, 6061-T4) AL-6061 aluminum alloy is a general purpose structural alloy developed by Alcoa in 1935. The temper designations mainly have 6061-T4, T451, AL 6061-T6, 6061-T651, etc.
What is the difference between 6061 and 6063 grade aluminum?
The difference between 6061 and 6063 is mainly in the end use. 6063 is a common grade used for custom extrusions. Its high corrosion resistance and good formability make it one of most joinable alloys. However, 6061 angle is the most commonly used aluminum for structural applications.
What is the specific gravity of Al 6061 aluminum?
Specific gravity: 2.7 Al-6061 Aluminum Physical Properties ASTM Alloy and Temper Density, g/cm3 (lb/in.3) Melting point, °C (°F) Specific heat capacity, J/kg·K (Btu/lb ·°F) Coefficient of thermal expansion, 10-6/K (μin./in. ·°F)
What is the -T6 temper of 6061-O aluminum billet?
To get to the -T6 temper, the 6061-O aluminum billet is heated to about 990˚ F, then quenched in water, then aged at about 350˚ F for around 8 hours. That changes the typical yield strength from 8 ksi to about 35 ksi (ksi is a unit of stress, equivalent to 1000 lbf/in 2 ).
