Hardness, Vickers | 175 | 175 | Converted from Brinell Hardness Value |
Ultimate Tensile Strength | 572 MPa | 83000 psi | AA; Typical |
Tensile Yield Strength | 503 MPa | 73000 psi | AA; Typical |
Elongation at Break | 11 % | 11 % | AA; Typical; 1/16 in. (1.6 mm) Thickness |
Elongation at Break | 11 % | 11 % | AA; Typical; 1/2 in. (12.7 mm) Diameter |
Modulus of Elasticity | 71.7 GPa | 10400 ksi | AA; Typical; Average of tension and compression. The compression modulus is about 2% greater than tensile modulus. |
Poisson’s Ratio | 0.33 | 0.33 | |
Fatigue Strength | 159 MPa | 23000 psi | AA; 500,000,000 cycles completely reversed stress; RR Moore machine/specimen |
Fracture Toughness | 20 MPa-m½ | 18.2 ksi-in½ | K(IC) in S-L Direction |
Fracture Toughness | 25 MPa-m½ | 22.8 ksi-in½ | K(IC) in T-L Direction |
Fracture Toughness | 29 MPa-m½ | 26.4 ksi-in½ | K(IC) in L-T Direction |
Machinability | 70 % | 70 % | 0-100 Scale of Aluminum Alloys |
Shear Modulus | 26.9 GPa | 3900 ksi | |

7079 Aluminum Thermal Properties
CTE, linear 68°F | 23.6 µm/m-°C | 13.1 µin/in-°F | AA; Typical; Average over 68-212°F range. |
CTE, linear 250°C | 25.2 µm/m-°C | 14 µin/in-°F | Average over the range 20-300ºC |
Specific Heat Capacity | 0.96 J/g-°C | 0.229 BTU/lb-°F | |
Thermal Conductivity | 130 W/m-K | 900 BTU-in/hr-ft²-°F | AA; Typical at 77°F |
Melting Point | 477 – 635 °C | 890 – 1175 °F | AA; Typical range based on typical composition for wrought products 1/4 inch thickness or more significant. Homogenization may raise the eutectic melting temperature by 20-40°F but usually does not eliminate eutectic melting. |
Solidus | 477 °C | 890 °F | AA; Typical |
