Fundamentals Types of Copper and Properties
1.1. Types of Copper and Properties. The copper most commonly used for sheet and strip applications complies with ASTM B370. It consists of 99.9 percent copper and is available in six tempers designated by ASTM B370 as 060 (soft) H00 (cold rolled) H01 (cold rolled high yield) H02 (half hard) H03 (three quarter hard) and H04 (hard).

A mill is a device that breaks solid materials into smaller pieces by grinding crushing or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g. via a hand crank) working animal (e.g. horse mill) wind or water ().
