    Abstract

    This specification deals with the standard requirements for palladium-copper alloy in the form of rod, wire, strip, and sheet material for use in electrical contacts. The specimen shall be produced from raw materials of such quality and purity by cold working, annealing, turning, grinding, or pickling. Material shall meet the chemical composition requirements for palladium, copper, silver, iron, zinc, cadmium, lead, and aluminum which shall be determined by spectrographic or chemical analysis. Temper test (hardness or tension) shall be conducted to determine the mechanical properties which shall be in conformity with the ultimate tensile strength, elongation, Knoop or Vickers microhardness, and Rockwell or Rockwell superficial hardness specifications. Visual examination shall be done on the furnished materials.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification covers a 60 % palladium-40 % copper alloy in the form of rod, wire, strip, and sheet material for electrical contacts.

    1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

    1.3 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 become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
