Standard Specification for Copper Alloy Strip for Flexible Metal Hose

SCOPE
1.1 This specification establishes the requirements for annealed copper-alloy strip for the manufacture of flexible metal hose produced from Copper Alloy UNS Nos. C41100 and C50500.
1.1.1 The nominal compositions are as follows:
Copper Alloy UNS No. Copper Zinc Tin
C41100 91.0 8.5 0.5
C50500 98.7 --- 1.3
1.2 The values stated in inch-pound units are to be regarded as the standard, except grain size, which is given in SI units. The values given in parentheses are for information only.
1.3 The following precautionary statement pertains only to the test method portion, Section 13, 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.
