Temper Designations for Cu and Cu Alloys -- Wrought and Cast


Standard ASTM B601 defines the terminology in general use for indicating the temper of copper and copper alloy products. Temper designations for copper and copper alloys are classified according to terminology used by U.S. manafacturers of copper and copper alloy products.

Standard ASTM B601 defines the terminology in general use for indicating the temper of copper and copper alloy products. It defines the terminology of the processes that produce the tempers and the observable changes in the product that result from the processes. Also it establishes an alphanumeric code for use in designating the product tempers.

In the following paragraphs, tempers are classified according to terminology used by U.S. manafacturers of copper and copper alloy products, and are arranged in alphabetical order with their designated code letters:
