Aluminium Shim: The Ultimate Guide
Let’s look at some of the fundamental aspects of aluminum shim. Before choosing aluminum shim, you should consider material grade, standard size, feature and classification, just to mention a few.
An aluminium shim is a thin strip made from aluminium used to position parts, make them suitable or minimize wear.
It is used mainly to fill up space in an object to adjust a component.
Aluminium shims are suitable for various industrial and practical applications and are corrosion resistant.

The following are the material grade to use for aluminium shims:
- 1100 H19
It is practically pure aluminium with low resistance. It has exceptional corrosion resistance, excellent welding properties, and good formability.
Heat treatment is unable to make it harder.
Grade 1145 is equivalent to Grade 1100. It offers similar formability while having a higher aluminium content; 99.45%
- 3003 H14
The manganese additive is more potent than Grade 1100 H19 and has excellent corrosion resistance. It cannot be heat treated.
- 6061 T6
Due to its strength, corrosion resistance, and machinability, grade 6061 T6 is undoubtedly the most popular. It can be heat treated.
- 5052 H34
High corrosion resistance, high formability, and Weldability are all attributes of grade 5052 H34. It cannot be heated.
- 2024 T3
Since copper has been added, grade 2024 T3 offers greater strength and good machinability. Copper makes it less resistant to corrosion.
It is extensively utilized in the aerospace sector.
Some of the uses:
- To level objects
Shim can be pushed between two objects to level the region if the object is not level.
- To fill gaps
It is used mainly in construction to fill an opening in the material to close the gap; hence the material becomes blush.
- To adjust clearance
In manufacturing, the shim is used to minimize the clearance between objects.
- To align pipes
Shims are used in plumbing to align pipes when doing repairs.
- Shims are used in computer manufacturing to protect the processor on a computer by keeping it apart from the heat sink.
Aluminium shim stock is a roll of thin gauge metal or foil used to make shims.
To enable precise positioning modifications, thin gauge cut sheet metal can be as light as 0.0005 inches (0.0127 mm).
Since the shim stock is so thin, standard equipment like metal shears may be readily used to cut it into unique shapes.
aluminum shim stock
Stamping, laser cutting, water jet cutting, machining, or other metal fabrication methods can tailor the shim stock for more complicated geometries or attain higher accuracy.
Arbor shims are created to prevent pivotal motion in assembled elements.
Shims are used in machinery adjustment and assembled for particular tolerances for an accurate fit.
They are measured by inner diameter, outer diameter and thickness.
Shim rings, also known as tolerance rings, are used to establish a firm grasp on stamped, moulded, or worn housing bearings.
They’re frequently used with retention rings to minimize play between machined parts.
Shim rings’ thickness and inner and outer diameter are all measured. Shim rings are identifiable by their inner diameter and thickness when placing an order.
Variable shims are classified into lengthening and shortening as they are used to shorten and lengthen shoulder bolts’ essential length.
They are primarily used in die and punch assemblies.
Lengthening shims are positioned at the shaft’s base over the threads while shortening shims are placed over the post under the head of the screw to shorten it.
They are measured by their inner and outer diameter and thickness.
Slotted shims exist in a variety of forms and have several uses. They all have an open slot, frequently in the shape of a U.
They can be used as standard spacers or placed around existing bolts and screws. Several types of slotted shim are equipped with tabs for more straightforward insertion.
Shims with slots are measured according to thickness, width, slot depth, and width. Shim height too is evaluated, but the additional tab length (if any) is not considered.
Additionally, the tapered opening is not included in the slot width calculation because it is determined from the slot’s narrowest point.
Shim stock is a thin, precise stock material used to make tailored shims.
It is a versatile material that may be quickly and easily cut with metal shears or scissors to desire sizes.
Shim stock is frequently employed for support, levelling, and fit modification.
The dimensions of shim stock are thickness, length, and width.
Although the recommended range is 0.15 – 1.9 mm, the thickness of aluminium shim stock typically varies from 0.25 to 1.0 mm thick.
- An aluminium shim can lessen the harm that spaces between parts and loose moving parts do to equipment.
- Aluminium shim eliminates extra gaps to guarantee the functions are accurate enough.
- It lessens erosion. Thus, you can significantly lengthen the lifespan of your engine.
- Economical to purchase and maintain.
The following are methods available for fabricating aluminium shims:
Forming as a method of aluminium shim fabrication distorts or bends the material to produce components and parts.
Forming also involves a comprehensive method using CNC press brakes known as rolling to form material parts.
The workpiece is shaped into the desired form by repeatedly feeding aluminium shims through parallel rollers.
Aluminium shims lose their form and not their mass through this fabrication process.
Punching is a fabrication process in which a material is removed from a piece of aluminium shim by applying a great enough shearing force.
This process produces cutouts and holes of different sizes and shapes.
Bending is a process that involves aluminium shim bending to fit in with the required specifications.
The following are the factors to consider before the aluminium shim bending process:
- Mechanical strength
- Surface areas that are analytic for appearance.
- Length, the expected deviations, and tolerances on the inside and outside dimensions.
The following are the standard material tolerances for aluminium shim stock:
Tolerance Shim stock thickness
+/- 0.00008 0.001”
+/- 0.0001 0.002”
+/- 0.00015 0.003”
+/- 0.0002 0.004”
+/- 0.00025 0.005”
+/- 0.0005 0.010”
+/- 0.0005 0.015”
+/- 0.0005 0.020”
+/- 0.00075 0.025”
+/- 0.0001 0.050”
+/- 0.0002 0.075”
+/- 0.0002 0.100”
+/- 0.0025 0.125”
Aluminium shim and thrust washer safeguard machined elements, function as a buffer, or minimize vibration.
Aluminium shims occupy space and level horizontal and inclined surfaces of interface components, whilst thrust washers disperse the weight of a bolt or screw
Thrust washers have rollover and breakout edges because of the stamping process. They are economical compared to aluminium shim.
Shims have symmetrical faces, flat margins, and smoother corner edges. The aluminium shim is exceptionally balanced and of a constant thickness.
This type of surface finish increases the thickness of an aluminium shim layer through the passive electrolytic process.
Aluminium shim is exposed to an acid solution to create a passive component by removing air from the surface.
The reactivity of the component’s surface is changed by the elements left behind to form more rust and corrosion resistance finish.
Passivation is considered the best next step because methods such as cutting, grinding, and welding alters the component surface.
Before the passivation process is applied, it is essential to ensure that the shim is cleaned; if not, the process will be unsuccessful.
The benefits of passivation are corrosion resistance is improved
Type of a surface finish in which paint is coated on the aluminium shim that functions as concrete hurdles against environmental conditions.
Painting is done in two modes:
- Painting by cataphoresis
- Chemical film
Shims that will be painted frequently go through a chemical film preparation method.
This method is a transformation coat that provides minor corrosion resistance and aesthetics and is sometimes known as blackening.
Black oxide has the benefit of not altering the shim thickness.
The following are the features to look for in aluminium shims:
The maximum strength the aluminium shim can endure renders it durable, thus an important feature to consider.
If the aluminium shim does not rust, it is corrosion-resistant.
The properties of resistance to corrosion help reduce the maintenance cost of treating the rust forming on the surface of the aluminium shim.
Formability And Weldability
Its ease of machinability is a crucial feature when choosing an aluminium shim.
Its ability to form into deferent shapes and sizes without weakening.
A tapered shim is a triangular-shaped piece of material that slips into any opening to fill it and stop the object from moving any further.
aluminum tapered shim
Tapered shims are employed when tight tolerance assembly is required, and the joining components are bent or angled; a typical straight shim cannot be utilized.
The aluminium gasket is a hydraulic seal that prevents leaking from or into the attached components.
At the same time, they are compressed by filling the area between two or more workpieces.
In contrast, an aluminium shim is a thin strip made from aluminium used to position parts, make them suitable or minimize wear.
The aluminium gasket is a bendable substance used to produce and maintain a static seal in an assembly under diverse operating circumstances.
In contrast, the aluminium shim is used to fill up space in an object mainly to adjust a component.
