The 260 brass shim stock with 1/2 hard temper has an unpolished (mill) surface and a standard tolerance, and meets American Society for Testing and Materials International ASTM B19 and B36 specifications. The 260 brass alloy is corrosion resistant and has good formability. It is nonmagnetic. The 1/2 hard temper is softer than 3/4 hard temper for increased formability.
Shim stock is very thin material that can be fabricated into specific shapes. Yield strength is the maximum stress a material can withstand before it will no longer return to its original shape. Corrosion resistance describes the materials ability to prevent deterioration caused by atmosphere, moisture, or other medium. Wear resistance indicates the ability to prevent surface damage caused by contact with other surfaces. Toughness describes the materials ability to absorb energy before breaking, while hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation. Formability indicates how easily the material can be permanently shaped. Machinability describes how easily it can be cut, shaped, finished, or otherwise machined.
