surface finish types

Machining

As-machined finish on a precision CNC milled part

Standard finish, surface roughness of 3.2 μm (125 μin), removes sharp edges and deburs parts cleanly.

✔ Metals
✔ Plastics

Anodizing

Anodized finish on an aluminum CNC milled part

Electrochemical process that forms a durable, corrosion-resistant oxide layer on the surface of metals.

✔ Aluminum

Alodine

Alodine conversion coating on an aluminum component

Chemical treatment process providing corrosion protection and surface preparation for paint adhesion.

✔ Aluminum
✔ Metals

Electropolish

Electropolished finish on a stainless steel component

Electrochemical process that smoothens, polishes, and deburrs metal surfaces to a high gloss.

✔ Stainless Steel ✔ Aluminum
✔ Copper

Electroplating

Electroplated finish on a precision metal component

Uses electric current to reduce dissolved metal cations to form a coherent metal coating.

✔ Metals

Electrolessplating

Electropolished finish on a stainless steel component

Deposition of a metal coating on substrates using an autocatalytic chemical process.

✔ Metals
✔ Plastics

Powder Coating

Powder-coated finish on a CNC milled component

Dry finishing process using powdered paint to provide a high-quality, durable finish.

✔ Metals
✔ Some Plastics

Black Oxidize

Black oxide finish on a machined steel component

Chemical bath that creates a black oxide coating on metal to improve corrosion resistance.

✔ Steel
✔ Iron

Polishing

Polished finish on a precision metal component

Smooths the surface to a bright, reflective finish; removes minor scratches and imperfections for aesthetic or functional purposes.

✔ Metals
✔ Some Hard Plastics

Sand Blasting

Uniform abrasive-blasted finish on an aluminum component

Powerfully propels blast media against surfaces to remove coatings and impurities.

✔ Metals
✔ Plastics

Brushed Finish

Brushed satin finish on a machined metal component

Mechanical polishing that produces a unidirectional satin finish.

✔ Metals

Tumbling

Tumbled finish on small precision machined components

Utilizes barrel or vibratory processes with abrasives to smooth and polish the surface of parts.

✔ Metals ✔ Glass
✔ Plastics
