Medical Device Silver Plating. Nickel undercoats should be applied for silver plating on copper and copper alloys. All our processes are certified to ISO This specification establishes the requirements for electrodeposited silver coatings that may be mat, bright, or semibright, and are usually employed as solderable surfaces and for their electrical contact characteristics, high electrical and thermal conductivity, thermocompression bonding, wear resistance on load-bearing surfaces, and spectral reflectivity.
This standard does not purport to address the safety concerns, if any, associated with its use. It also offers excellent corrosion resistance and solderability. Tarnish Resistance To increase the tarnish resistance of the silver plating, supplementary coatings such as a painting or powder coating can be recommended depending on subsequent finishing steps and solderability.
Whether you have low or high volume plating requirements, our experts can guide you through the plating process required of your industry. Some of these applications include: Coatings shall be sampled, tested, and conform accordingly to specified requirements as to nature, purity, appearance, defects, adhesion, solderability, hardness, spectral reflectance, electrical conductivity, hydrogen embrittlement relief, and thickness measured either nondestructively by beta backscatter, X-ray spectrometry, or magnetic method, or destructively by coulometric technique or microscopical cross-sectioning procedure.
Corrosion Protection A nickel undercoat with silver plating can be used for applications where corrosion protection is important. When a nickel undercoat is not used on copper and copper alloy materials or when a copper undercoat is used on other materials, then the silver plating service should not be used for continuous service at a temperature in excess of degrees Fahrenheit.
It also offers protection form fretting erosion and has strong corrosion resistance.

As it is not a rare, naturally occurring metal, silver oxidizes quickly but out of all the astn, its the one that is the most electrically and thermally conductive.
Our state-of-the-art equipment allows us to meet tolerances of 25 micro inches. Coatings shall undergo preplating operations such as stress relief treatment, strike, and underplating, as well b70 post-plating embrittlement relief.

Without supplementary tarnish-resistant treatment.
Silver plating is best used for applications in electronics and engineering where good solderable surfaces and good corrosion resistance are required; for high electrical and thermal conductivity in electrical contacts, for thermo-compression bonding, sound reproduction applications, electrical applications that require spectral reflectivity, and other types of electronic applications. Silver plating is a highly electric conductive and has satm properties for contacts and connectors.
The adhesions of the silver plating can be adversely affected due to a weak copper and silver inter-metallic asgm. 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. 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.
Our extensive quality control measures zstm production include non-destructive testing in accordance with ASTM to measure the thickness of the coating. Historical Version s – view previous versions of standard.
