10 Types Of Aluminum Finishes
Product designers and manufacturers employ different surface finishes for aluminum parts. There are various aluminum finishes, each with unique properties and practical use. Below are the typical types of aluminum finishes.
1. As Machined Finish
The as-machined finish is the original state of the machined aluminum part as it exits the mill. It doesn’t cost extra for surface finishing and is widely used for applications without mechanical or chemical finish requirements.
Aluminum CNC machining offers parts with a cleared machined pattern surface roughness range of Ra 0.2 – 3.2µm, depending on the application’s requirement. As-machined aluminum finishing meets tight tolerances accurately. However, your aluminum parts may show visible machine tool cutting marks.
