Yield strength of aluminum 6061 T6

6061-T6. T6 temper 6061 has an ultimate tensile strength of at least 42,000 psi (290 MPa) and yield strength of at least 35,000 psi (241 MPa). In thicknesses of 0.250 inch (6.35 mm) or less, it has elongation of 8% or more; in thicker sections, it has elongation of 10%.

6061 aluminum vs 7075

6061 aluminum is a general purpose, low cost alloy that can be easily machined to tight tolerances. It offers good corrosion resistance and weldability. The magnesium content makes it a valuable choice for parts requiring a formable product.

7075 aluminum has a high strength-to-weight ratio and superior corrosion resistance because of its alloy content. The titanium and copper make it even stronger and more resistant to heat than the 6061 aluminum, but engineering properties are not as good because it cannot be easily machined to tight tolerances.

7075 Aluminum has higher strength and lower weight than 6061 aluminum but has lower hardness.
