What are stainless steel shims used for?
Shims are available in a wide selection of materials, from brass and copper, to PTFE and even paper. They are a thin strip of material often used for aligning parts to make them fit. Shims are also great for reducing wear.
What is the purpose of shims?

What makes a good shim?
Plain Carbon Steel – The most common choice for shims that will exist in interior applications and not be exposed to weather. Typical A-36 or Multigrade Carbon Steel will have a compressive strength of approximately 22,000 psi.
What are Aluminum shims used for?
In plumbing repairs: Shims are used to align pipes when a plumber needs to do some repairs. In computer manufacturing: Shims are even used to protect the processor on a computer.

The versatile airframe has found uses in a variety of other roles, including as a gunship ( AC-130 ), for airborne assault, search and rescue, scientific research support,…
Why aren’t shims used on metal aircraft structures anymore?
Modern production processes used for metal aircraft structures take advantage of things like accurate CNC machines, laser alignment equipment, and determinant positioning techniques that minimize the need for shimming at assembly. So you don’t see a whole lot of shims being used on new metal aircraft structures anymore.
What are shims used for in construction?
A couple of packages of shims on the shelf in your home workshop will always find a use. When installing cabinetry, for example, shims are indispensable for leveling base cabinets along the floor or adjusting wall cabinets so they are perfectly plumb.
