Engineering Alloys Material Properties Table
Standard mechanical properties lookup for structural steel, stainless steel, aluminum, copper, and titanium alloys.
Overview & Scope
Mechanical properties of engineering alloys play a vital role in design. Selecting the correct material requires balancing strength, density, and stiffness parameters to ensure safety margins while optimizing total weight.
Technical Sizing Values
The dynamic table below details fundamental properties including density, elastic modulus, and yield/ultimate strengths. Values represent average nominal values.
| Material | Density (g/cm³) | Density (lb/in³) | Elastic Modulus (GPa) | Elastic Modulus (Mpsi) | Yield Strength (MPa) | Yield Strength (ksi) | Tensile Strength (MPa) | Tensile Strength (ksi) |
|---|---|---|---|---|---|---|---|---|
| Structural Steel (A36) | 7.85 | 0.284 | 200 | 29 | 250 | 36 | 400 | 58 |
| Stainless Steel (304) | 8 | 0.289 | 193 | 28 | 215 | 31.2 | 505 | 73.2 |
| Aluminum Alloy (6061-T6) | 2.7 | 0.098 | 68.9 | 10 | 276 | 40 | 310 | 45 |
| Titanium Alloy (Ti-6Al-4V) | 4.43 | 0.16 | 113.8 | 16.5 | 880 | 128 | 950 | 138 |
| Copper Alloy (C101) | 8.94 | 0.323 | 117 | 17 | 69 | 10 | 220 | 32 |
Engineering Notes & Best Practices
- •Structural steel (A36) is isotropic and offers identical strength characteristics in all directions.
- •Aluminum 6061-T6 is heat-treated; welding can lower strength in the heat-affected zone.
- •Titanium alloys provide exceptional strength-to-weight ratios for aerospace applications.
