ASTM B441-04

Standard Specification for Copper-Cobalt-Beryllium, Copper-Nickel-Beryllium, and Copper-Nickel-Lead-Beryllium Rod and Bar (UNS Nos. C17500, C17510, and C17465)

ABSTRACT
This specification establishes the requirements for copper-cobalt-beryllium alloy (UNS No. C17500), copper-nickel-beryllium alloy (UNS No. C17510), and copper-nickel-lead-beryllium alloy (UNS No. C17465) rods and bars in straight lengths. Tempers available under this specification are: TB00 (solution heat treated (A)), TF00 (precipitation hardened (AT)), TD04 (solution heat treated and cold worked: hard (H)), and TH04 (hard and precipitation heat treated (HT)). Materials shall be tested and adhere to mechanical (tensile strength and Rockwell hardness), electrical conductivity, and chemical composition requirements.
SCOPE
1.1 This specification establishes the requirements for copper-cobalt-beryllium alloy (UNS No. C17500), and copper-nickel-beryllium alloy (UNS No. C17510) rod and bar in straight lengths.
1.2 The intent is to provide a system of interchangeable alloys.
1.3 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units, which are provided for information only and are not considered standard.
1.4 The following hazard statement pertains only to the test method portions of this specification: 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.
