The following bibliographic material is provided to assist you with your purchasing decision:


This specification covers seamless round and rectangular including square copper alloy tube in straight lengths. The following copper alloys are specified and classified according to their nominal compositions: UNS No. C22000, UNS No. C23000, UNS No. C26000, UNS No. C27000, UNS No. C27200, UNS No. C27400, UNS No. C28000, UNS No. C33000, UNS No. C33200, UNS No. C37000, and UNS No. C44300. The tempers of drawn tube shall be designated as light-drawn (H55), drawn (H58), and hard-drawn (H80). Light-drawn (bending) temper is used only when a tube of some stiffness but yet capable of being bent is needed. Drawn temper is for general purposes and is most commonly used where there is no specific requirement for high strength on the one hand or for bending qualities on the other. Hard-drawn temper is used only where there is need for a tube as strong as is commercially feasible for the sizes indicated. For any combination of diameter and wall thickness not covered under hard-drawn temper, the values given for drawn temper shall be used. The tempers of annealed tube shall be designated as light anneal (O50) and soft anneal (O60). The tubes shall undergo mechanical tests such as tension test, Rockwell hardness test, and expansion test in order to determine certain properties such as tensile strength and hardness. A mercury nitrate test shall be done to detect and remove mercury vapor. Nondestructive tests such as eddy-current test, hydrostatic test, and pneumatic test shall be done as well.

(A) Alloy Designations of Specification B135 – 63, which was published in the 1966 Book of ASTM Standards, Part 5.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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 non-conformance with the standard.

1.3 Warning—Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury containing products. See the applicable product Safety Data Sheet (SDS) for additional information. Users should be aware that selling mercury and/or mercury containing products into your state or country may be prohibited by law. (See 10.1.)2

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
