Standard Specification for Copper-Zinc-Tin and Copper-Zinc-Tin-Iron-Nickel Alloys Plate, Sheet, Strip, and Rolled Bar

ABSTRACT
This specification covers the requirements for plates, sheets, strips, and rolled bars of copper-zinc-tin and copper-zinc-tin-iron-nickel alloys with Copper Alloy UNS Nos. C40500, C40810, C40850, C40860, C41100, C41300, C41500, C42200, C42500, C42520, C43000, and C43400. Materials shall be processed by hot working, cold working, and annealing as to produce a uniform wrought structure in the finished product. Tempers shall be available in the rolled, as hot rolled, or annealed conditions. Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (thickness, length, width, mass, straightness, and edges), mechanical (tensile strength, and Rockwell hardness), chemical composition, and grain size requirements.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
