Custom precision machining parts aluminum We are one of the top CNC parts suppliers based in China. This series of non standard CNC tuning parts feature with black anodized process and the material is pure aluminium. Anodized surface treatment helps to develop an anodized layer on the part surface and further improve the physical property, such as better color application, higher corrosion resistance and durability. What’s more, any bright color could be achieved to make the part look nicer or low key. Thus, anodized treatment are most widely used on a CNC machined aluminium parts.
