Introduction

Temper designations for copper alloys and copper products are indicated by the standard ASTM B601. This standard defines the terminology of the processes responsible for the production of tempers and is also based on the occurrence of changes within the product during these processes. An alphanumeric code is developed by the standard ASTM B60. This coding system is used to provide designations to the product tempers.

The tables given below highlight the classification of tempers according to terminology used by manufactures of copper alloy and copper products in the US.
