Standard Specification for Copper-Cobalt-Beryllium Alloy and Copper-Nickel-Beryllium Alloy Strip and Sheet
STANDARD published on 1.5.2022
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 strips and sheets of copper-cobalt-beryllium and copper-nickel-beryllium alloys with Copper Alloy UNS Nos. C17410, C17450, and C17460. The materials for manufacture shall be cast billets or slabs 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, which shall be rolled to finished size and heat treated when required to meet temper properties. Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (thickness, length, width, straightness, and edge contours), mechanical (tensile and yield strength, Rockwell hardness, and elongation), electrical conductivity, and chemical composition requirements.
