Product Description

Precision etched shim washers made from brass and stainless steel are high-accuracy metal components manufactured through chemical etching technology. This process allows the production of extremely thin and complex shim shapes with burr-free edges, consistent thickness, and excellent dimensional accuracy.

Compared with traditional stamping or machining methods, chemical etching eliminates mechanical stress and deformation, making it ideal for precision spacing, alignment, and tolerance adjustment in mechanical assemblies. Brass materials offer excellent electrical conductivity and machinability, while stainless steel provides superior strength, corrosion resistance, and durability.

Our etched shim washers are available in a wide range of thicknesses, shapes, and custom sizes. Common materials include SUS301, SUS304, SUS316 stainless steel and C2600 brass. These precision shims are widely used in automotive components, electronic devices, precision instruments, industrial machinery, and aerospace applications.

OEM and ODM customization is supported according to customer drawings or samples. With advanced etching technology and strict quality control, we ensure stable production quality and reliable performance for global customers.
