Our standard finish is an “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.
A finishing CNC machining operation can be applied to the part to reduce its surface roughness. The standard smoothing surface roughness (Ra) is 1.6 μm (64 μin). Machine marks are less evident but still visible.
Brushing is produced by polishing the metal with grit resulting in a unidirectional satin finish. Not advisable for applications where corrosion resistance is required.
Passivation is a treatment method to protect the metal from corroding, it generates a more uniform formation of a passive surface that is less likely to react with air and cause corrosion chemically.
Type III anodizing provides excellent corrosion and wear resistance, suitable for functional applications.
Electropolishing is an electrochemical process used to polish, passivate and deburr metal parts. It is useful to reduce surface roughness.
Chromate conversion coating（Alodine/Chemfilm） is used to increase the corrosion resistance of metal alloys while maintaining their conductive properties.
Bead blasting adds a uniform matte or satin surface finish on a machined part, removing the tool marks. This is used mainly for visual purposes and comes in several different grits which indicate the size of the bombarding pellets.
Powder coating is a strong, wear-resistant finish that is compatible with all metal materials and can be combined with bead blasting to create parts with smooth and uniform surfaces and excellent corrosion resistance.
Black oxide is a conversion coating used to improve corrosion resistance and minimize light reflection.
