(Specification)Standard Specification for Copper-Nickel-Tin Spinodal Alloy Strip
Standard Specification for Copper-Nickel-Tin Spinodal Alloy Strip
ABSTRACT
This specification establishes the requirements for copper-nickel-tin spinodal alloy strips with Copper Alloy UNS Nos. C72700, C72900, and C72650. Tempers are available as follows: TB00 (solution heat treated), TD01 to TD12 (solution heat treated and cold worked), TX00 or TS01 to TS12 (spinodal hardened), or TM00 to TM08 (mill hardened). Materials shall be prepared and tested accordingly to examine their conformance to mechanical (tensile and yield strength, elongation, ductility, and bend ratio), chemical composition, and grain size requirements. Retests shall be performed on any lot of material that fails to adhere to specified requirements due to inadequate heat treatment, or fails to meet bend test requirements.
SCOPE
1.1 This specification establishes requirements for copper-nickel-tin alloy strip in the following alloys:
Copper Alloy UNS No.Nominal Composition Weight % CopperNickelTin C7270085 96 C7290077158 C7265087.5 7.55
1.2 Units—The values stated in inch-pound units and the values stated in SI units in Table 5 are to be regarded as standard, except for grain size which is stated in metric units only. The values given in parentheses are mathematical conversions to SI units and are provided for information only and are not considered standard.
1.3 The following safety hazard caveat pertains only to the test method(s) described in this specification.
1.3.1 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.
