The Complete Surface Finish Catalog

Anodizing (Type II & III)

Color & Hardcoat for corrosion & wear resistance.

Powder Coating & Painting

Durable industrial finishes for extreme environments.

Electroplating

Zinc, Nickel, Chrome for wear resistance & conductivity.

Bead Blasting & Brushing

Matte and textured cosmetics to hide machining marks.

Polishing & Electropolishing

Mirror finishes & precise Ra reduction.

Passivation & Black Oxide

Rust prevention for steel components.

Precision Ra Control for Critical Applications

Precision control over surface roughness from Ra 3.2 μm (As Machined) down to Ra 0.1 μm (Mirror Finish) for critical aerospace and medical applications. Our finishing processes are calibrated to meet your exact Ra specification with CMM and profilometer verification.

Material & Finish Compatibility

Not all finishes work on all materials. Use our compatibility matrix below to select the optimal surface treatment for your specific base material.

⬡

Aluminum (6061 / 7075 / 5052)

Lightweight, excellent machinability — broadest finish compatibility of any base material.

Anodizing (Type II & III)

Color & Hardcoat for corrosion and wear resistance. MIL-A-8625 compliant.

Adhesion

Durability

Powder Coating

Durable decorative finish. RAL color matching. Requires chromate pre-treatment.

Adhesion

Durability

Chem Film (Alodine)

MIL-DTL-5541 corrosion protection. Conductive. Used as primer base for paint.

Adhesion

Durability

Bead Blasting

Uniform matte surface with consistent Ra finish. Ideal pre-treatment for anodizing.

Adhesion

Durability

⚠

Note: Aluminum alloys with >2% copper content (e.g. 2024) may have reduced anodizing quality. Consult our engineers for 7075-T6 Type III hardcoat requirements.

◈

Stainless Steel (304 / 316 / 17-4 PH)

High corrosion resistance in raw form. Finishing focuses on aesthetics and enhanced resistance.

Electropolishing

Removes surface material for mirror-bright finish. Improves corrosion resistance 30–50%.

Adhesion

Durability

Passivation

ASTM A967 / AMS 2700. Removes free iron; enhances native chromium oxide layer.

Adhesion

Durability

Powder Coating

Requires sand-blast pre-treatment for proper adhesion on stainless surfaces.

Adhesion

Durability

PVD Coating

Physical Vapor Deposition — TiN / CrN hard coatings for tooling and decorative use.

Adhesion

Durability

⚠

Note: 316L is recommended for marine / chloride environments. Passivation does not apply to 400-series ferritic grades without special process adjustment.

◧

Carbon Steel (1018 / 1045 / 4140)

Prone to oxidation — surface treatment is mandatory. Broad coating compatibility.

Powder Coating

Most cost-effective durable finish for carbon steel. Requires iron phosphate pre-treatment.

Adhesion

Durability

Black Oxide

Hot alkaline blackening. Minimal dimensional change (0.0001"). Oil post-treatment required.

Adhesion

Durability

Zinc Electroplating

Sacrificial zinc layer. ASTM B633 standard. Clear, yellow or black chromate conversion.

Adhesion

Durability

Hot-Dip Galvanizing

Structural corrosion protection for heavy-duty environments. ASTM A123.

Adhesion

Durability

⚠

Note: High-strength steels (>1100 MPa / 36 HRC) require hydrogen embrittlement bake-out post-plating per ASTM F519. Confirm grade before ordering zinc plating.

◉

Copper & Brass (C101 / C260 / C360)

Excellent electrical / thermal conductivity. Finishes selected to preserve or enhance these properties.

Electroplating (Nickel)

Bright or satin nickel for wear and tarnish resistance. Retains bulk conductivity.

Adhesion

Durability

Electroplating (Gold)

Hard gold (99.7% Au) for PCB contacts and connectors. 0.5–5.0 µm thickness range.

Adhesion

Durability

Electroplating (Tin)

RoHS-compliant solderable coating for electronics applications. ASTM B545.

Adhesion

Durability

Bead Blasting

Satin matte finish for cosmetic copper/brass parts. Excellent as plating base prep.

Adhesion

Durability

⚠

Note: Free-machining brass (C360) contains lead — surface treatments on food-contact or medical parts must use lead-free certified process lines. Declare application at order time.
