Abstract

This specification establishes the requirements for seamless round, rectangular, and square copper tube (UNS Nos. C10100, C10200, C10300, C10800, C12000, and C12200) suitable for general engineering applications. The material of manufacture shall be billets, cast bars, or tube. The tube shall be manufactured by hot- and cold-working processes, shall be cold drawn to the finished size and wall thickness, and shall be supplied in cold-drawn or annealed temper condition. The material shall conform to the chemical composition requirements prescribed for copper, phosphorus, and arsenic, as determined by chemical analysis, and to the mechanical property requirements including tensile strength, yield strength, Rockwell hardness, and straightening. Requirements for grain size, electrical mass resistivity, and dimensions are specified. The following test methods are detailed: grain size, electrical resistivity, tensile and yield strength, and hardness tests, expansion test for round table, microscopical examination, test for hydrogen embrittlement, and nondestructive tests such as electromagnetic (eddy-current), hydrostatic, and pneumatic pressure tests.

Scope

1.1 This specification establishes the requirements for seamless round, rectangular, and square copper tube suitable for general engineering applications.

1.1.1 Tubes made from any of the following Copper UNS No. designations shall be supplied unless otherwise specified in the contract or purchase order:

Copper UNS No.Type of Copper
C10100 Oxygen-free electronic
C10200 Oxygen-free without residual deoxidants
C10300 Oxygen-free, extra low phosphorus
C10800 Oxygen-free, low phosphorus
C12000 Phosphorus deoxidized, low residual phosphorus
C12200 Phosphorus deoxidized, high residual phosphorus

1.2 This specification is the SI companion to Specification B75.

1.3 The following hazard statement pertains only to the test method described in Sections 20.5.2.1, 21.2.9, and 21.2.10 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.
