Chromate conversion coating, more commonly known by its brand name Alodine, is a chemical coating that passivate and protects aluminum from corrosion. It is also used as a base layer before priming and painting parts.

Available surface finishes
Here is a list of standard surface finishes. For custom surface finishes such as electroplating or polishing, please contact email@example.com.
Our standard finish is “as machined” finish. It has a surface roughness of 3.2 μm (126 μin). All sharp edges are removed and parts are deburred. Tool marks are visible.
Media blasting uses a pressurized jet of abrasive media to apply a matte, uniform finish to the surface of parts.
Anodizing is an electrolytic passivation process that grows the natural oxide layer on aluminum parts for protection from wear and corrosion, as well as for cosmetic effects.
Nickel plating is a process used to electroplate a thin layer of nickel onto a metal part. This plating can be used for corrosion and wear resistance, as well as for decorative purposes.
Parts are manually polished in multiple directions. Surface is smooth and slightly reflective.
Powder coating is a process in which a dry powder paint is applied to a metal surface. Unlike traditional, liquid paint, powder coating does not need a solvent to keep the binder and filler of the paint in liquid suspension.
Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes.
Painting involves spraying a layer of paint onto the surface of the part. Colors can be matched to a Pantone color number of the customer’s choosing, while finishes range from matte to gloss to metallic.
Black oxide is a conversion coating similar to Alodine that is used for steel and stainless steel. It is used mainly for appearance and for mild corrosion resistance.
Part marking is a cost-effective way to add logos or custom lettering to your designs and is often used for custom part tagging during full-scale production.
