Anodizing is a “Conversion Coating” and is very different than painting or other metal coating. While paints and plating sit on top of the surface of the aluminum, anodizing converts the outer layer of aluminum to aluminum oxide, so the coating is fully integrated with the aluminum substrate. This is why anodizing doesn’t chip or flake like paint- it is completely integral with the underlying metal. The anodizing will start to show wear after several uses along the edges, but should not flake or chip.
Because anodizing involves running an electric current through the part to be anodized, parts must be gripped by conductive racks or wires. Where these racks or wires contact the part, there will be slight un-anodized marks or “contact points” left on the surface of edges of the parts.
Machining marks: These marks are just visible lines or striping that occur during the machining process. They add a little unique, handmade touch.
You will see anodizing & machining marks on the following colors: Silver, Golden Rod.
