Dab tsi yog qhov txawv ntawm 6061-O thiab 6061-T6 txhuas ntawv?

6061-O aluminum sheet and 6061-T6 aluminum sheet are two common specifications of aluminum sheets in the 6000 series 6061. Lawv muaj cov yam ntxwv zoo dua. Dab tsi yog qhov txawv ntawm 6061-O thiab 6061-T6 txhuas ntawv? Qhov sib txawv tseem ceeb ntawm 6061-O thiab 6061-T6 txhuas daim hlau yog lawv cov khoom siv kho tshuab, especially strength and hardness, which are affected by the tempering process.

6061-O aluminum plate:

Kub: O (annealed)

Mechanical behavior:
Tensile zog: Typically approximately 124 MPa (18 ksi ua)
Yield zog: Typically approximately 55 MPa (8 ksi ua)
Elongation: usually around 25%
Hardness: lower
Formability: Excellent formability due to its softness. It can be molded, khoov, and molded easily without cracking or weakening.

Typical uses:
Typically used in applications where high strength is not a critical requirement but formability and corrosion resistance are critical.
Ideal for applications requiring deep drawing or forming processes such as automotive parts, cans and kitchenware.

6061-T6 aluminum plate:

Condition: T6 (solution heat treatment and artificial aging)
Mechanical behavior:
Tensile zog: Typically approximately 310 MPa (45 ksi ua)
Yield zog: Typically approximately 275 MPa (40 ksi ua)
Elongation: usually around 12%
Hardness: Harder compared to 6061-O due to precipitation hardening process.
Formability: Although still formable, 6061-T6 is less ductile than 6061-O due to increased strength and hardness. It may require more force to bend or form.

Typical uses:
Structural applications requiring high strength and good corrosion resistance, such as aerospace components, bicycle frames and structural components in construction.
Machined components requiring high strength and excellent machining properties.
