Comparison of 1060-H28 Aluminum vs. 1100-H28 Aluminum

Dec. 24, 2024

1060-H28 and 1100-H28 aluminum are both high-purity aluminum alloys, primarily composed of aluminum, with very similar alloy compositions. Both are supplied in the H28 condition, which indicates a certain degree of strain hardening and partial annealing. Although these two alloys have similar chemical compositions, they exhibit differences in various mechanical, electrical, thermal, and cost-related properties.

Mechanical Properties: 1100-H28 offers higher tensile strength, yield strength, fatigue strength, and shear strength, making it suitable for applications that require high strength and durability. 1060-H28 is more suitable for applications that require good thermal conductivity and electrical conductivity.
Thermal Properties: 1060-H28 has better thermal conductivity and thermal diffusivity, making it ideal for applications with high heat dissipation requirements.
Electrical Properties: 1060-H28 offers higher electrical conductivity, making it suitable for electrical and electronic applications.
Cost and Environmental Impact: The cost difference between the two is minimal, but the metal price of 1060-H28 is slightly higher, and the environmental and energy consumption impacts are very similar.
