260 Brass Shim Stock Roll, Half Hard Temper, Meets ASTM B19/ASTM B36 Specifications, 0.005" Thick, 12" Width, 120" Length

Product Features

• Brass 260 shim stock can be cut more easily than steel and has good corrosion resistance
• Half-hard temper hardens the material, leaving it moderately flexible and formable
• Conforms to specifications ASTM B19, ASTM B36, SAE-CA 260, and Fed. Spec. QQ-B-613
• Rockwell superficial hardness of 30-T 56 to 58

The brass 260 shim stock roll has a half-hard temper for dimensional stability and can be cut more easily than steel shim stock. The material’s 30% nominal zinc content provides increased hardness without affecting the good corrosion resistance of its copper base. This nonmagnetic material, also called cartridge brass, can be brazed and soldered, but may be susceptible to stress corrosion cracking. The half-hard temper has increased the material’s hardness and yield strength ratings, which provides dimensional stability during use but also leaves the material moderately flexible and formable. This roll has a Rockwell superficial hardness rating of 30-T 56 to 58 and conforms to the American Society for Testing and Materials (ASTM) B19 and B36, Society of Automobile Engineers (SAE) CA 260, and Federal Specification (Fed. Spec.) QQ-B-613 standards.

Shim stock is fabricated by cold rolling, which is the process of reducing a material’s thickness by passing it between two rollers. Cold rolling can cause a temper to form in the material, increasing the yield strength (the amount of force necessary to permanently bend or deform the material) as well as hardness ratings of the material. The higher its hardness and yield strength ratings, the more likely the shim is to preserve its thickness and shape over time while in use, but the harder it will be to bend and shape.
