    Abstract

    This specification establishes the requirements for rods and bars in straight lengths of copper-beryllium alloys with Copper Alloy UNS Nos. C17000, C17200, and C17300. The material for manufacture shall be cast and worked to such purity and soundness as to be suitable for processing by hot working, cold working, and annealing to produce a uniform wrought structure and specified temper in the finished product. Products shall be available in the following tempers: solution heat-treated TB00 (A), and cold-drawn hard TD04 (H), which shall be precipitation heat treated after machining or forming. Products that are already precipitation heat treated by the manufacturer shall be available in tempers TF00 (AT) and TH04 (HT). Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (diameter, length, straightness, and edge contour), mechanical (tensile and yield strength, Rockwell hardness, and elongation), and chemical composition requirements.

ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification establishes the requirements for copper-beryllium alloy rod and bar in straight lengths. The following three alloys are included:

    Copper Alloy
    UNS No.

    1.2 Unless otherwise required, Copper Alloy UNS No. C17200 shall be the alloy furnished whenever Specification B196/B196Mis specified without any alloy designation.

    1.3 The values stated in either inch-pounds or SI units are to be regarded separately as the standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

    1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
