An Al-Mg-Si alloy with the composition 6061 has excellent corrosion resistance, good ductility, and medium strength. In particular, it is a promising alloy with many applications since it exhibits little tendency for stress corrosion cracking, great weldability, strong corrosion resistance, and cold workability. It is ideal as a material for architectural ornamentation since it can be anodized, tinted, and enamel coated. Its strength is higher than 6063's due to the small amount of Cu present, but it also has a higher quenching sensitivity than 6063. It requires re-solidification treatment, quenching, and aging to acquire better strength because it cannot achieve wind quenching after extrusion.
6061 alloy aluminum sheet is a medium strength alloy aluminum sheet with good weldability, corrosion resistance, and oxidation properties. Trucks, buildings, ships, trams, furniture, mechanical parts, precise machining, industrial materials, etc. may all be made using it.

Heat Treatment Process of 6061 Aluminum Sheet
6061 alloy aluminum sheet common temper contains O, T4, T6 and T651, the difference between 6061-T6 aluminum sheet and 6061-T651 aluminum sheet is that in general, the internal stress of 6061-T6 will be larger, processing will be deformed, the suitable processing state should be 6061-T651 aluminum sheet, he is on the basis of T6 stretching, eliminate internal stress. 6061-T6 aluminum sheet bending 90 degrees is easy to crack.

6061-O |
Hardened 6061 (6061-O hardened) has a greater 6061 aluminum sheet manufacturer's ultimate compressive strength of no more than 150 MPa (22 ksi) and a greater tensile strength of no more than 83 MPa (12 ksi) or 110 MPa (16 ksi). The elongation (tensile before ultimate destruction) of this raw material is 10-18%. To obtain a better quenching condition, the aluminum alloy is generally heated at 415°C for 2-3 hours. |
|
6061-T4 |
T4 hardened 6061 has a minimum ultimate compressive strength of 180 MPa (26 ksi) or 210 MPa (30 ksi) and a minimum tensile strength of 110 MPa (16 ksi). Elongation is 10-16%. |
|
6061-T6 |
It has a minimum ultimate compressive strength of 290 MPa (42 ksi) and a minimum tensile strength of 240 MPa (35 ksi). More typical values are 310 MPa (45 ksi) and 270 MPa (39 ksi), respectively. |
