Standard Specification for Copper and Copper Alloy Forging Rod, Bar, and Shapes
STANDARD published on 1.4.2020
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification establishes the requirements for copper (UNS Nos. C11000, C14500, and C14700) and copper alloy (UNS Nos. C36500, C37000, C37700, C46400, C48200, C48500, C61900, C62300, C63000, C63200, C64200, C64210, C65500, C67500, C67600, C69300, C70620, C71520, and C77400) forging rods, bars, and shapes. The material for manufacture shall be a cast rod, bar, or billet of such purity and soundness as to be suitable for processing by hot working, cold working, and annealing to produce a uniform wrought structure in the finished product. Products shall be produced in tempers H50 (extruded and drawn), M20 (as hot rolled), and M30 (as hot extruded). Products shall be tested and shall adhere to dimensional (diameter, thickness, width, length, shape, and straightness), mechanical, and chemical composition requirements.
