Comparison of hardness between aluminum alloy and galvanized iron

Comparing the hardness characteristics of aluminum alloy and galvanized iron comprehensively, we can find that the hardness of galvanized iron is higher than that of aluminum alloy in general.

This is mainly because the ferrite and cementite structure in galvanized iron provide it with high hardness, while the hardness of aluminum alloy can be adjusted by adding alloying elements, but its hardness is still lower than that of galvanized iron on the whole.

However, when selecting materials, besides hardness, other factors such as density, corrosion resistance and cost need to be considered. Aluminum alloy has low density and corrosion resistance, which makes it more suitable in some specific application scenarios. Therefore, in practical application, various factors should be comprehensively considered according to specific needs and scenarios, and suitable materials should be selected.
