Hard anodize

• Coating penetrates the aluminum base metal as well as building up on the surface.
• Very hard, ceramic‑like coating with good abrasion resistance (varies by alloy and thickness).
• Color varies from light tan to black depending on alloy and thickness; can be dyed darker colors at suitable thicknesses.
• Good dielectric properties.
• Corrosion resistance is generally good; sealing in a dichromate solution is recommended where additional corrosion resistance is required.
• Commonly used for hydraulic components, wear surfaces, actuating cams and similar parts where hardness and wear resistance are important.

Sulfuric anodize

• Versatile anodize for aluminum; best base for dyeing in a wide range of colors.
• Color of undyed coating depends on alloy; low‑alloy aluminum shows little visible change.
• Used where decorative coloring and/or corrosion resistance are required.

Black oxide coating (for ferrous metals)

• Uniform decorative black coating for ferrous materials.
• Provides limited standalone corrosion protection; typically used with supplementary treatments such as oil.
• Common where dimensional change must be minimal and where reduced light reflection or a black appearance is desired.

Chemical films (conversion coatings on aluminum)

• Thin chemical conversion coating for aluminum, typically used as a base for paint.
• Color can range from nearly colorless to golden/iridescent brown.
• Used where a combination of conductivity and corrosion resistance is needed or for touch‑up where anodize has been removed.

Chrome plating

• Hard, wear‑resistant coating with low coefficient of friction and good heat resistance.
• Available in bright (high‑polish) and satin (matte) finishes.
• Used both decoratively (typically over copper and nickel undercoats) and for engineering purposes such as wear surfaces, erosion resistance and surfaces requiring low friction.

Electroless nickel plating

• Uniform nickel coating, including in recesses and cavities, with little edge buildup.
• Color similar to stainless steel.
• Offers good corrosion resistance when applied to sufficient thickness.
• As‑plated hardness is relatively high and can be further increased by heat treatment.
• Used where uniform coverage, hardness, lubricity and corrosion resistance are important.

Electropolishing

• Electrolytic process that smooths and brightens metal surfaces by removing a controlled amount of material.
• Can reduce or remove burrs, scratches and sharp edges.
• Produces finishes ranging from satin to mirror‑bright, depending on material and process parameters.

Gold plating

• Yellow to orange color depending on process and basis metal; can be matte or bright.
• Offers good corrosion and tarnish resistance.
• Provides low electrical contact resistance and good conductivity.
• Used for decorative applications and in electronic and electrical components where reliable contact surfaces are required.

Nickel plating (electrolytic)

• Can be deposited in soft or hard, dull or bright forms depending on process.
• Color can resemble stainless steel or appear dull gray to light gray.
• Corrosion resistance depends on total coating thickness and underplate.
• Used decoratively and for engineering purposes on steel, zinc and zinc alloys, and copper alloys.

Passivation (stainless steel)

• Chemical process that removes free iron from the surface of corrosion‑resistant alloys.
• Helps improve corrosion resistance and is often used as a final treatment on stainless steels and related alloys.

Phosphate coatings

Light phosphate coating

• Used mainly as a pretreatment and paint base.
• Can also be used as a pretreatment prior to plating.

Heavy phosphate coating

• Provides heavier coatings for corrosion and wear resistance.
• Certain heavy zinc phosphate coatings can help reduce galling in operations such as extrusion and deep drawing.

Bright acid tin plating

• Gray‑white in plated condition; can achieve high luster when fused.
• Soft and very ductile with good corrosion resistance at appropriate thicknesses.
• Excellent solderability.
• Used where solderability and corrosion protection are needed on suitable substrates.

Zinc plating

• Available in bright or dull finishes; bright zinc can resemble bright chrome in appearance.
• Provides sacrificial corrosion protection for steel; zinc will corrode preferentially to protect the base metal.
• Often used with chromate or other post‑treatments to enhance corrosion resistance and appearance.

Notes on specifications

• Many finishes listed reference common industry and military specifications (for example, certain MIL, QQ and ASTM standards) and indicate where processes are RoHS compliant.
• The finishes page on the website is for reference only and advises contacting Denver Metal Finishing to verify that a specific process, spec or thickness range is currently offered for your application.
