HM, Your Leading Custom Anodizing Parts Supplier

Anodizing is an electrochemical process that creates a strong, corrosion-resistant, and durable anodic oxide surface. At our innovative HM China factory, we place custom CNC machined aluminum parts in an acid bath and send an electric current through it.

We specialize in the 3 main types of anodizing—each great for a different purpose. Type I anodizing uses chromic acid to produce a thin coating used as paint primer. Types II and III use sulfuric acid to create a thick, hard coat for industrial applications. Also, other acids are used to anodize aluminum parts for aerospace and corporate applications.

Anodizing layer thickness improves wear resistance, corrosion resistance, electrical and thermal insulation, and ability to retain lubricants and PTFE coatings.

Anodizing Parts For Any Industry


Anodized aluminum parts are commonly used in the aerospace industry because of the strength-to-weight ratio, resistance to wear and corrosion. Typically, hard coats of Type III are used in this industry, such as for the construction of Boeing aircrafts.


Automakers use aluminum for applications that include wheels, frames, cylinder heads, wheels, gearbox housings, pistons, anti-lock brake components, transmission parts, radiators and bumpers. An anodized finish is the only one in the metals industry that satisfies all requirements of a high-performance vehicle.

It depends on your desired and exact details.

You can freely request the desired color for any aluminum products and parts.

What are the Different Variations of Anodizing Parts Process?

The anodizing parts process has different variations; these are:

Anodized Type I

The anodized type I is the basic and common anodized process. Chromic acid is the primary chemical used for this process to ductile the anodized aluminum part’s layer.

Anodized Type II

Sulfuric acid is essential for anodized type II. The anodized type II is perfect for coloration applications because it primarily uses sulfuric acid.

Anodized Type III

This process is similar to anodized type II that also uses sulfuric acid. It is known as a hard anodizing part. 

What are the Applications of Anodizing Methods?

The anodizing method is applicable in different aluminum and metallic parts.

How to Make Sure If the Anodizing Parts Process is Successful?

It is very important to make sure the anodizing process is successful.

Here are some tips on how to identify or check if the anodizing process is successful:

  • It should be best if the checker examines the parts’ matt surface.
  • You can use some scratch test equipment or tools.
  • Also, check for color dispersal.

If you notice the color of parts is uniform, then the anodizing is successful.

But when the color is unequal, it means the anodizing procedure is not wealthy.

Moreover, the successful anodizing process will identify if the parts or products are well-formed and don’t have any peeling presence.

How Much Does the Cost for Anodizing Parts?

How Long Can Anodizing Parts Keep?

Unlike the other finishing or coating procedures, anodizing aluminum products and parts will never peel easily.

Anodizing process produces a border coating on the texture of the aluminum parts that are secured at the molecular station.

 The proper anodizing for aluminum parts should never wear for multiple decades.

All anodized products and parts can retain their original appearance with more than 5 years.

However, the existence of anodized parts will depend on the anodizing method used.

Is it Worth It to Anodize the Aluminum Parts?

Anodized Parts

Anodizing parts or products will improve the wear and corrosion resistance; that’s why the anodizing process is often needed to accomplish better product properties.
