In simple terms, 3105 painted aluminum sheet is approximately 98% pure aluminum. Manufacturers add certain alloys to improve the material’s strength while preserving desirable traits, like a lighter weight and corrosion resistance. These additions make 3105 a more suitable choice for certain applications.
Conducting more detailed research can help you decide whether Champagne Metals’ 3105 painted aluminum sheet is the right painted aluminum grade for your needs.

Generally speaking, painted aluminum sheet 3105 has the following percentages of components in its chemical makeup:
| SI | FE | CU | MN | MG | CR | ZN | TI |
|---|---|---|---|---|---|---|---|
| 0.60% | 0.70% | 0.30% | 0.30-0.80% | 0.20-0.80% | 0.20% | 0.40% | 0.10% |
The remainder of the product is aluminum.
Mechanical properties for 3105 painted aluminum sheet differ slightly based on its temper.
For example, an H12 temper — 1/4 hard — conforms to ASTM Standard B209, which specifies it must have a minimum yield strength of 15 kilopounds per square inch (ksi). Minimum and maximum tensile strength must be 19 ksi and 26 ksi, respectively. The minimum elongation percentages vary between 1% and 3%, based on the material’s thickness.
Conversely, an H14 temper — 1/2 hard — must boast a minimum yield strength of 18 ksi. Tensile strength should be between a minimum of 22 ksi and a maximum of 29 ksi. Depending on the thickness, the material’s minimum elongation percentage should be between 1% and 2% to meet ASTM B209.
| Grade | Strength | Elongation | |
|---|---|---|---|
| Temper | Ultimate Tensile Strength (min-max) | Ultimate Yield Strength (min) | % at 50 mm |
| H12 | 19-26 ksi | 15 ksi | 1-3 |
| H14 | 22-29 ksi | 18 ksi | 1-2 |
