Specs ASTM B135

The following copper alloys are specified and classified according to their nominal compositions: Ten alloys are specified having the following nominal compositions: Hard-drawn temper is used only where there is need for a tube as strong as is commercially feasible for the sizes indicated. This specification covers seamless round and atsm including square copper alloy tube in straight lengths.

Caution should be taken when handling mercury and mercury containing products. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or 1b35 to date. 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.


ASTM B / BM – 17 Standard Specification for Seamless Brass Tube

The tempers of drawn tube shall be designated as light-drawn H55drawn H58and hard-drawn H Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.

Nondestructive tests such as eddy-current test, hydrostatic test, and pneumatic test shall be done as well. This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Historical Version s – view previous versions of standard.

Link to Active This link will always route to the current Active version of the standard. Combining values from the two systems may result in non-conformance with the standard. A mercury nitrate test shall be done to detect and remove mercury vapor. For any combination of diameter and wall thickness not covered under hard-drawn temper, the values given for drawn temper shall be used.


Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. 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.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

C, and UNS No. Light-drawn bending temper is used only when a awtm of some stiffness but yet capable of being bent is needed.

Ten alloys are specified having the following nominal compositions:. The tempers of annealed tube shall be designated as light anneal O50 and soft anneal O
