Suitable Choice of Material

As a professional aluminum spacer supplier from China, HM uses many aluminum alloys to fulfill your unique requirements. We work with Acd12, A380, ZLD104, Al 6061, Al 6082, Al 6063, Al 075, and other alloys available for custom spacers.

Al 6061 is typically optimal for most spacers due to its excellent weldability, corrosion resistance, and compatibility with anodizing.

High-Precision Options

At HM, our CNC machines have tight tolerances of 0.002um, allowing us to supply high-precision aluminum parts. Such accuracy is crucial for the functionality of aluminum spacers.

Our products will fit your projects like a perfect puzzle piece.

Metric Aluminum Spacers

Although standard aluminum spacers are measured in Imperial inches, our custom services allow you to request metric aluminum spacers. The hole sizes can range from 3-12mm, and outer diameters may measure at 6-19mm.

You can request any custom length aluminum spacers for your application.

Anodized Aluminum Spacers

Aluminum spacers are often anodized to improve their hardness and corrosion-resistance. HM offers multiple anodizing options, with types I, II, and III anodizing.

We also offer polishing, sand blasting, chrome plating, zinc plating, powder coating, and other surface treatments as per your requirement.

What is the Purpose of Aluminum Spacer Blocks?

These aluminum-made spacer blocks are ideal for various pipes and conduits trench. It is a framework suit around the end of every pipe. 

Aluminum Spacer Blocks

Various bore pipes are designed to have attached spacer blocks. The aluminum spacer blocks are commonly square that support the circular frames. 

The aluminum spacer blocks are valuable for installing multiple pipelines in one bore to avoid damages. When installing spacer blocks, you must have a larger bore to ensure suitably block dimensions.

What are the Standard Features of Aluminum Spacer Blocks?

The aluminum spacer blocks have multiple standard features, including:

Raised the V-groove support plate off of the track

Allows you to move the transmission components like screws

Suitable with several liner executors

Maximizes transmission spacing

Made from high-quality aluminum

Commonly has about 55 grams weight

What are Industrial Applications of Aluminum Spacer Blocks?

What is Processing Services Available for Aluminum Spacer Blocks?

Below are some processing services offered for aluminum spacer blocks.


CNC machines do the turning process. When the workpiece pivots, the distinct point cutting material settles stationary ahead of its axis.

The process operates according to the machine. Each of the cutting materials or the pieces functions to reach material removal.


This process is also ideal for machining aluminum spacer blocks. It functions as cutting more-point along its axis rotates.

Milling Aluminum

The workpiece consistently stays on its axis. Either the cutting material or the workpiece does the feed motion during operation. Combining both can also do the process.


Drilling Aluminum

The drilling process does the workpiece holing. The specific sizes’ points rotating cutting material moves straight to the drilled surfaces in such a process. Drilling using CNC machines achieves adequate holes.

What are the Surface Treatments for Aluminum Spacer Blocks?

Custom aluminum spacer blocks are manufactured with various surface treatments depending on applications or requests.

Some of them are:

  • Zinc Plating

Zinc plating the aluminum spacer blocks uses the zincate process and the cyanide solution next. 

You can ask HM for a more proper zinc plating surface treating your spacer blocks.

  • Engraving

Engraving aluminum spacer blocks give permanent marking and a high-contrasted aluminum surface.

The best-engraved aluminum surface combines immense average power and maximum peak power.

  • Sand Blasting

Sandblasting aluminum spacer blocks allows removing the paints. Even sandblasting is typical for steel materials, there are some occurrences where aluminum sandblasting treatments are needed.

The aluminum spacer blocks can also be polished, anodized, and brushed.
