CONTAINED IN VOL. 02.05, 2017 Includes requirements for electrodeposited palladium coatings containing at least 99.7 mass % of palladium metal.

1.1This specification covers requirements for electrodeposited palladium coatings containing at least 99.7 mass % of palladium metal. Composite coatings consisting of palladium with a thin gold overplate for applications involving electrical contacts are also covered.

1.2Properties—Palladium is the lightest and least noble of the platinum group metals. It has a specific gravity of 12.0, which is substantially less than gold (19.3) and platinum (21.5). This yields a greater volume or thickness of coating and, consequently, some saving of metal weight accompanied by a small sacrifice in corrosion resistance and reflectivity. The following table compares the hardness range of electrodeposited palladium with other electrodeposited noble metals and alloys (1,2).2

Approximate Hardness (HK25)

Gold

50–250

Palladium

75–600

Platinum

150–550

Palladium-Nickel

300–650

Rhodium

750–1100

Ruthenium

600–1300

1.3The values stated in SI units are the preferred values. Values provided in parentheses are for information only.

1.4This 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.
