Standard Speciﬁcation for
Aluminum Bronze Sheet, Strip, and Rolled Bar
1
This standard is issued under the ﬁxed designation B169/B169M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.
A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*
1.1 This speciﬁcation
2
establishes the requirements for cop-
per alloy UNS Nos. C61300 and C61400 aluminum bronze
sheet, strip, and rolled bar.
1.2 The products made to this speciﬁcation are commonly
used for drawing, forming, stamping, and bending applications
and are not intended for electrical applications.
NOTE 1—The products produced under this general speciﬁcation may
be used in many applications in which the individual requirements may be
too speciﬁc to be determined by normal physical or mechanical testing.
Therefore, it may be advisable for the purchaser to submit samples or
drawings to the manufacturer to be assured that the product furnished is
suitable for the intended application.
NOTE 2—Refer to Speciﬁcation B171/B171M for plate product.
1.3 Units—The values stated in either inch-pound units or
SI units are to be regarded separately as standard. Within the
text, SI units are shown in brackets. The values stated in each
system are not necessarily exact equivalents; therefore, to
ensure conformance with the standard, each system shall be
used independently of the other, and values from the two
systems shall not be combined.
1.4 The following safety hazard caveat pertains only to the
test method(s) described in 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, health, and environ-
mental practices and determine the applicability of regulatory
limitations prior to use.
1.5 This international standard was developed in accor-
dance with internationally recognized principles on standard-
ization established in the Decision on Principles for the
Development of International Standards, Guides and Recom-
mendations issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee.
