The materials that are commonly used for precision and slotted shims are aluminium, rust-resistant stainless steel, cold-rolled steel strip, brass, and laminated plastic (PET). The materials are divided into two categories: those for solid sheet and those for laminates.
In addition to the commonly used standard materials listed above, there are a number of special materials that can be used and processed upon request.
Materials for solid shims
Solid individual shims can be processed in thicknesses between 0.05 mm to 20 mm. Our standard shims’ material specifications can be found in the following table. If you require other materials, we would be happy to check your inquiry for availability.

Special materials upon request
The individual layers of laminates are available in even lower thicknesses for solid individual shims. Solid shim foil thicknesses begin at 0.025 mm. In addition to metallic materials, layered precision shims are available in lighter laminated plastic that is easier to peel. Laminated shim stock can also be delivered in a condition that is compliant with the relevant standard for aerospace technology: LN-29557 (AMS-DTL-22499).
