Aluminum Surface Treatments & Finishing Services

Alfiniti anodizes the aluminum it manufactures, with standard etch (201R1), bright dip (205R5), two-step black, hard coat, and Frostkote acid-etch finishes, in clear or a range of colors, to MIL-A-8625 Type I, II, and III, Class 1 (non-dyed) or Class 2 (dyed). We anodize parts up to 27 feet long, and run a special bendable anodized process for parts that are formed after finishing.

Anodizing builds a hard, corrosion-resistant oxide layer that becomes part of the metal, so it will not chip or peel, and it can be left clear, dyed to color, or bright-dipped to a mirror-like shine. Bright dip in particular is offered by few US shops, and we run it in-house at length. Tell us the look, color, and coating class you need and we will confirm the alloy, temper, and process to hit it.

Common applications:

• Architectural trim and storefront framing
• Hardware and consumer-product housings
• Marine and outdoor components
• Decorative bright trim and reflectors
• Parts needing a hard, wear-resistant surface

Alfiniti powder coats your aluminum parts in the color and finish you specify, applying a dry powder paint that is electrostatically charged and baked on for a thick, even, hard-wearing surface with no runs or drips. Because we manufacture the aluminum we coat, powder coating combines with cutting, machining, and forming on one order.

Powder coating resists chips, scratches, fading, and corrosion better than most wet paints, which makes it a strong choice for parts that live outdoors or take abuse. Send your color, gloss level, and any spec requirements and we will match them.

Common applications:

• Outdoor furniture and architectural products
• Railings, fencing, and guardrail
• Enclosures, frames, and chassis
• Automotive and trailer parts
• Consumer goods needing a tough finish

Alfiniti paints and color-matches your aluminum parts to the color, gloss, and specification you supply, including wet paint in multiple colors and CARC (Chemical Agent Resistant Coating) for defense applications. Give us a color standard, a sample, or a paint code and we will match it.

Wet painting suits parts that need a specific color, a fine finish, or a coating spec that powder cannot meet, and it pairs with our pre-treatment step for strong adhesion. We finish parts from prototype through production alongside our cutting, machining, and forming.

Common applications:

• Defense and government parts (CARC)
• Color-matched components for branded products
• Parts with strict color or gloss specs
• Touch-up and repair finishing
• Mixed assemblies needing one consistent color

Alfiniti prints directly onto your aluminum parts, adding logos, part numbers, fill lines, graduations, instructions, and other markings as part of the finishing run, so parts arrive labeled and ready to use. We work from your artwork and placement.

Printing is applied after coating or anodizing so the mark sits on the finished surface, and it combines with the rest of your order. Send your artwork, placement, and color and we will reproduce it.

Common applications:

• Branded logos and product identification
• Part numbers and serial marking
• Measurement graduations and fill lines
• Control panels and labeled tubes
• Safety and instruction markings

Alfiniti sands your aluminum parts to remove tool marks, weld spatter, and surface defects and to create an even, uniform texture, either as a finished look or as the prep step before painting, powder coating, or anodizing.

Sanding is part of our mechanical-finishing range, which also includes polishing and brushing, and it combines with the rest of your order so parts leave consistent and ready for the next step. Tell us the surface you need and we will sand to it.

Common applications:

• Surface prep before paint or powder
• Removing weld marks and blemishes
• Even, uniform satin textures
• Knocking down sharp edges
• A consistent look before anodizing

Alfiniti polishes, buffs, and brushes your aluminum parts to the finish you want, from a hand-rubbed satin to a bright, near-mirror surface, using graded emery from roughly 120 through 220 grit and round-tube polishing where the profile allows.

Mechanical polishing is also the ideal prep for a bright anodize or bright dip, where a smooth base surface gives the brightest result. Tell us the finish level you are after and we will match it, and pair it with anodizing if you want the shine locked in.

Common applications:

• Bright trim and decorative components
• Round tube and handrail
• Parts to be bright-anodized or bright-dipped
• Satin or brushed consumer products
• Visible architectural aluminum

Alfiniti blasts your aluminum parts to a clean, uniform matte texture, using graded media from very fine through coarse to hit the finish you specify, either as a final look or as surface prep that gives paint, powder, and anodize a strong mechanical key.

Blasting strips light oxidation and surface marks and leaves an even, non-directional finish that hides handling. It combines with the rest of your order. Tell us the texture and finish you need and we will blast to it.

Common applications:

• Uniform matte architectural finishes
• Surface prep before coating
• Removing oxidation and surface marks
• Even, non-directional textures
• Parts that hide fingerprints and handling

Alfiniti pre-treats your aluminum parts before any coating, cleaning, degreasing, and etching the surface (including caustic and acid etch) and applying conversion coatings where needed, so paint, powder, and anodize bond tightly and resist corrosion underneath.

Pre-treatment is the step that decides whether a finish lasts, which is why we build it into the finishing line rather than treating it as an extra. We match the pre-treatment to your chosen finish and spec. Tell us the coating you are after and we will prep for it.

Common applications:

• Adhesion prep before paint or powder
• Surface conditioning before anodizing
• Conversion coatings for corrosion resistance
• Removing oils, oxides, and contaminants
• Meeting coating-spec surface requirements
