C and C shall be furnished as: Combining values from the two systems may result in non-conformance with the standard. The product also shall be inspected with a longitudinal wave test from the external circumferential and end surfaces.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Active view current version of standard. This specification establishes the requirements for copper and copper die forgings produced by hot pressing asrm. Alternatively, samples may be taken from separately forged test bars of the same heat as the forgings in the lot provided the wall thickness and amount of working for the test bar are equivalent to those for the forgings.

Soldering is rated as “excellent”, brazing is rated as “good”, oxyacetylene welding is “not recommended”, gas shielded arc welding is “not recommended”, coated metal arc welding is “not recommended”, spot welding is “not recommended”, seam welding is “not recommended”, and butt welding is rated as “fair”. They are given merely to indicate to the purchaser the various forging types and some dimensional toler- ances used on commercially designed hot-pressed forgings up to 2 lbs 0.

G Iron content shall not exceed nickel content. Copper-nickel alloys C and C are intended for welded axtm with seawater exposure.

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. The following copper and copper alloys are included: The following copper and copper alloys are included: The machinability rating of this alloy is Copper-nickel alloys C and C are intended for welded applications with seawater exposure.

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