Hello,
There are several possibilities.
The first is to choose a hard aluminum alloy, such as EN AW-7075, which Xometry offers in its standard materials.
Alternatively, or in addition, it may be recommended to request a type III "hard" sulfuric anodization treatment, which improves surface hardness and protects parts from shocks, scratches, and wear in general.
A standard anodization, type II, may be sufficient, depending on the uses.

Hello everyone, I need advice on surface finishes to improve the wear resistance of aluminum parts. Any suggestions?

Thank you very much! So I will turn to a 7075 aluminum with an anodization treatment
