1060 aluminum and 1100-H14 aluminum are both common industrial aluminum alloys, and they have similarities in many performance aspects. However, they differ in certain specific properties, which make each alloy more suitable for different applications.
These differences highlight that 1100-H14 offers excellent strength and fatigue resistance, while 1060 aluminum offers better electrical and thermal conductivity. Both alloys are very similar in many performance aspects, but the subtle differences may make one more suitable than the other depending on the specific application.
The choice of alloy depends on the specific application requirements. For electrical and thermal conduction-related applications, 1060 aluminum would be the preferred choice, while for applications requiring strength and fatigue durability, 1100-H14 aluminum would be more suitable.
Although 1060 aluminum and 1100-H14 aluminum have similar primary alloy compositions, being based on pure aluminum, their slight compositional differences result in different mechanical properties:
1060 Aluminum: Its purity is typically above 99.6%, with almost no other alloying elements, primarily used in electrical and thermal conduction applications.
1100-H14 Aluminum: Also part of the pure aluminum series, but small amounts of copper (Cu) and other elements are added to enhance its strength and fatigue resistance.
| Element | 1060 Aluminum | 1100-H14 Aluminum |
| Aluminum (Al), % | 99.6 to 100 | 99 to 99.95 |
| Copper (Cu), % | 0 to 0.050 | 0.050 to 0.2 |
| Iron (Fe), % | 0 to 0.35 | 0 to 1.0 |
| Magnesium (Mg), % | 0 to 0.030 | 0 |
| Manganese (Mn), % | 0 to 0.030 | 0 to 0.050 |
| Silicon (Si), % | 0 to 0.25 | 0 to 1.0 |
| Titanium (Ti), % | 0 to 0.030 | 0 |
| Vanadium (V), % | 0 to 0.050 | 0 |
| Zinc (Zn), % | 0 to 0.050 | 0 to 0.1 |
| Residuals, % | 0 | 0 to 0.15 |
The yield strength of 1100-H14 aluminum is higher than that of 1060 aluminum, meaning that 1100-H14 aluminum can withstand greater pressure without permanent deformation before the load reaches a certain level. Therefore, 1100-H14 is more suitable for applications requiring higher structural strength.
1100-H14 aluminum outperforms 1060 aluminum in fatigue strength. Fatigue strength refers to the maximum stress a material can withstand under repeated loading. The higher fatigue strength makes 1100-H14 aluminum more suitable for applications that experience dynamic loads or alternating stresses, such as automotive and aerospace structural components.
