Anodizing

Anodizing is the aluminium-specific finishing route in our catalogue. It grows a controlled oxide layer on the surface of an aluminium part, allowing colour, appearance and selected surface-performance requirements to be specified without changing the underlying 7075-T6 or other aluminium substrate. The process is arranged through external finishing partners per order.

01 / Process fundamentals

What Is Anodizing?

Anodizing is an electrochemical process that grows a controlled aluminium-oxide layer from the surface of an aluminium part. The oxide is porous before sealing, so the process can also introduce dye for colour before the surface is sealed.

Unlike plating, anodizing does not deposit a separate metal layer onto steel or chromoly. It is an aluminium finishing route, which is why alloy selection, machining marks, edge geometry and the desired colour all matter before the part leaves machining.

“Plain” in a product specification is a finish option, not a colour claim. Red, black, purple, blue, green and pink are listed colour options on documented aluminium rod end lines; the actual colour, finish type and acceptance standard are confirmed for the order.

02 / Finish selection

Anodizing vs Plating

Question	Anodizing	Plating
Substrate	Aluminium and its alloys	Often steel or another conductive substrate, depending on the finish
How the layer forms	Controlled oxide grows from the aluminium surface	A separate metal layer is deposited onto the substrate
Primary reasons to choose it	Colour, appearance and selected surface-performance requirements	Corrosion protection, wear or low-friction working surface
Dimensional question	Layer growth and sealing must be considered at fits and edges	Plating thickness and masking must be considered at threads and bores

The practical rule: choose anodizing when the aluminium substrate and the required appearance or surface behaviour make an oxide finish appropriate. It is not a universal substitute for zinc, hard chrome or powder coating.

03 / Production route

Machined aluminium route

Machine first, finish second

Rod ends, adjusters and clevises are machined to the required geometry before anodizing. The drawing review covers the surfaces to mask, the finished fit and the appearance expected after colour and sealing.

Specification route

Colour is not the whole requirement

The product catalogue documents colour options, but a production order still needs the finish type, substrate, critical interfaces and acceptance standard. Consistent appearance across a batch is considered alongside the functional fit.

What Anodizing Makes Possible

Colour-coded rod ends

Red, black and other listed colours distinguish aluminium rod end families while keeping the underlying 7075-T6 body visible as the chosen substrate.

Lightweight adjusters

Anodized aluminium linkage adjusters and male or female rod ends support lightweight assemblies where steel is not required.

Machined brackets and clevises

Rear brake clevises and similar machined aluminium parts can use anodizing, polishing or other documented finish options.

Appearance with a defined fit

Colour selection is paired with masking and dimensional review so the finish does not compromise threads, bores or contact faces.

Material boundary: anodizing is for aluminium and its alloys. The product examples below are predominantly 7075-T6 aluminium; steel and chromoly parts follow plating, black oxide or coating routes instead.

06 / Quality control

How Anodized Parts Are Controlled

Colour consistency matters, but the machined interfaces and the aluminium substrate matter just as much.

Alloy and preparation

The aluminium grade, machined surface and preparation requirements are checked before the external finish route is released.

Masking and fit

Threads, bores, bearing seats and contact faces are identified so the finished layer does not interfere with assembly.

Visual consistency

Colour, surface appearance and batch consistency are checked against the agreed product or order acceptance standard.

Final inspection

Dimensions and any agreed finish documentation are checked before finished parts are released.

Machining marks remain relevant

Anodizing follows the prepared surface. Tool marks, edge breaks and burr removal should be planned before the part is sent out.

Colour and alloy interact

Different aluminium alloys and surface conditions can influence colour and appearance. The acceptance standard should be agreed for the actual batch.

Protect the interfaces

Specify masking and allowance for threads, bores and fits so the visual finish does not compromise assembly.

08 / Questions

Anodizing FAQ

Do you operate your own anodizing line?

No. Anodizing is arranged through external finishing partners after machining or fabrication, with the finish and checks defined per order.

Which materials can be anodized?

Anodizing is an aluminium finishing route. Our documented product examples are primarily 7075-T6 aluminium; the actual alloy is confirmed from the drawing.

What colours are available?

Current product specifications list Red, Black, Plain, Purple, Blue, Green and Pink options on documented aluminium rod end lines. Colour availability for a custom part is confirmed for the order.

Is Plain a colour?

Plain is a listed finish option, not a colour claim. The page uses the product specification’s wording and separates it from the listed colour variants.

Can anodizing be used on a bearing fit or thread?

It can be considered, but the layer, masking and final dimension must be designed into the route. Send the fit tolerance and surfaces that must remain functional.

Do you offer Type II or Type III anodizing?

Type II and Type III are general industry categories. The specific partner capability and finish type for your order are confirmed during drawing review rather than assumed.

Can you anodize machined clevises as well as rod ends?

Yes, the rear brake clevis product specification lists anodizing among its finish options. Similar custom parts are reviewed from the drawing and material.
