The B and C scales overlap, such that readings below HRC 20 and those above HRB 100, generally considered unreliable, need not be taken or specified. Typical values include: Very hard steel (e.g. chisels, quality knife blades ): HRC 55–66 (Hardened High Speed Carbon and Tool Steels such as M2, W2, O1, CPM-M4, and D2, as well as many of the ...
T6 temper 7075 has an ultimate tensile strength of 510–540 MPa (74,000–78,000 psi) and yield strength of at least 430–480 MPa (63,000–69,000 psi). It has a failure elongation of 5–11%. [9] The T6 temper is usually achieved by homogenizing the cast 7075 at 450 °C for several hours, quenching, and then ageing at 120 °C for 24 hours.
7068-T6511 has typical ultimate tensile strength of 710 MPa (103 ksi) versus a similar product produced from 7075-T6511 that would have a typical ultimate tensile strength of 640 MPa (93 ksi). Typical yield strength for alloy 7068-T6511 is 683 MPa (99.1 ksi) versus 590 MPa (86 ksi) for a similar product produced from 7075-T6511. [2]

It cannot be work hardened, but is commonly heat treated to produce tempers with a higher strength but lower ductility. [1] Alternate names and designations include AlSi1MgMn, 3.2315, H30, and A96082. The alloy and its various tempers are covered by the following standards: [2] EN 485-2: Aluminium and aluminium alloys. Sheet, strip and plate.
It can be cold worked to produce tempers with a higher strength but a lower ductility. [1] Alternate names and designations include AlMg3, 3.3535, and A95754. The alloy and its various tempers are covered by the following standards: [2] ASTM B 209: Standard Specification for Aluminium and Aluminium-Alloy Sheet and Plate
Typical material properties for 6005A aluminum alloy include: [2] Density: 2.71 g/cm 3, or 169 lb/ft 3. Electrical Conductivity: 47 to 50% IACS. Young's modulus: 70 GPa, or 10 Msi. Ultimate tensile strength: 190 to 300 MPa, or 28 to 44 ksi. Yield strength: 100 to 260 MPa, or 15 to 38 ksi. Thermal Conductivity: 180 to 190 W/m-K.
Alloy 5083 retains exceptional strength after welding. It has the highest strength of the non-heat treatable alloys with an Ultimate Tensile Strength of 317 MPa or 46000 psi and a Tensile Yield Strength of 228 MPa or 33000 psi. It is not recommended for use in temperatures in excess of 65 °C. [2]
