What is Aluminum Spacer Used For?

Custom Aluminum Spacer Services

An aluminum spacer is designed to decrease the case of tear and wear between objects.

The aluminum spacer is typically used for separating the assemblies from each other.

This component is applied to create bigger internal spaces.

This is usually used where compact grit is needed.

Moreover, the aluminum spacer is being attached to increase the airflow.

It is utilized to prevent components from connecting and averting the electrical shortage.

The aluminum spacer is generally used in different industries, such as furniture, machinery, hardware, and construction.

This component is particularly used for electron insulation, panel supports, led standoffs, and other applications.

How to Custom Your Aluminum Spacers?

Custom Aluminum Spacer Services

The aluminum spacer is highly produced through the mechanical procedure.

They can be customized in different details, shapes, sizes, and styles.

It is made from aluminum alloy or natural aluminum materials known as durable and long-lasting materials.

In addition, the aluminum spacer can be produced and customized from different finishing and surface treatments, such as polishing, electroplating, powder coating, and more.

This element is well-formed, ensuring the best and well-finished output.

They can be custom and constructed using the different processing methods, such as:


The cutting procedure is very important in achieving the right measurement, length, and width of an aluminum spacer. With the help of a cutting machine, the aluminum spacer can be cut to size in the standard and any custom sizes.


Punching is a great procedure for volume aluminum spacer production. This is a low-cost procedure but an efficient way to produce aluminum spacer. This procedure may require different tools.

Injection Molding

The injection molding is a majority production used for shaping the aluminum spacer. The aluminum spacer is difficult to shape, but injection molding can be more manageable. With the help of injection molding, the perfect shape of aluminum space is extremely achieved.


The CNC milling processing method is great for the smaller and higher production volumes. This processing method can reduce the possibility of human errors.


Since most aluminum spacers are customized in cylindrical or round shapes, turning is ideal. Turning reaches the perfect cylindrical shapes of the aluminum spacer.

What are the Standard Specifications of Aluminum Spacer?

The aluminum spacer is available in different specifications.

A standard material used for an aluminum spacer is the 6061-T6 aluminum materials.

Moreover, the aluminum spacer hole’s sizes are from #2 up to #12.

The aluminum spacer’s length measurement is about ⅛ up to 1 ½ inch.

However, the aluminum spacer can be custom-made in different outdoor diameter measurements.

What are the Features of Aluminum Spacers?

The aluminum spacer is consisted of various desirable and unique features, making them so great for most applications.

These are the following features of the aluminum spacer:

Premium Quality

The custom-made aluminum spacer is highly produced from superior and high-quality aluminum materials. Aluminum spacers are particularly strong that ensure a high-quality structure and performance.

Unique Agility

An aluminum spacer has a unique and uncommon ability. This is fabricated with standard thickness achieving the best agility.

Excellent Temperature-Resistant

Aluminum spacer achieves excellent resistance to high-temperature situations. Due to its unique strength, the aluminum spacer can handle different temperatures of any application.


The aluminum spacer is not prone to rust because aluminum has superior contrary against rust. This spacer can extremely resist rust and other specks of dirt.

High Sturdiness

The popular strong and durable material used for spacer products is aluminum. The aluminum spacer has enough durability to last longer and handle any harsh application.
