The recommended hot working temperature for this alloy is between and F. Link to Active This link will always route to the current Active version of the standard. 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”.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Originally approved in C copper-zinc-silicon C copper-nickel C copper-nickel C nickel silver, This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Material shall be tested using a square, rectangular, or circular transducer having an effective area of 1 in.

Indications that appear between these points shall be evaluated on the basis of a straight line joining the two peak amplitudes. C and C shall depend only on tensile strength. The hot forgeability rating of this alloy is Holes are to be drilled to midsection and the bottom of the hole shall be parallel to the entrant surface. By agreement between manufacturer and purchaser, limits may be established and analysis required for unnamed elements.

This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. Where Alloy FC Brass is The following copper and copper alloys are included: The following copper and copper alloys are included: Material and Manufacture 6.

The annealing temperature for this alloy is between and F. The machinability rating of this alloy is 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.

This abstract is a brief summary of the referenced standard. 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. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
