The following copper alloys are specified and classified according to their nominal compositions: For any combination of diameter and wall thickness not covered under hard-drawn temper, the values given for drawn temper shall be used. This specification covers seamless round and rectangular including square copper alloy tube in straight lengths.

This abstract is a brief summary of the referenced standard.

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

The tempers of annealed tube shall be designated as light anneal O50 and soft anneal O 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. Ten alloys are specified having the following nominal compositions: Light-drawn bending temper is used only when a tube of some stiffness but yet capable of being bent is needed.


A mercury nitrate test asrm be done to detect and remove mercury vapor. Hard-drawn temper is used only where there is need for a tube as strong as is commercially feasible for the sizes indicated. The tempers of drawn tube shall be designated as light-drawn H55drawn H58and hard-drawn H The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Combining values from the two systems may result in non-conformance with the standard.

Specs ASTM B135

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. Caution should be taken when handling mercury and mercury containing products. 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.

Ten alloys are specified having the following nominal compositions:. C, and UNS No.
