Some of atm applications include: Without supplementary tarnish-resistant treatment. Nonmagnetic Coatings on Magnetic Basis Metals.
It also offers protection form fretting erosion and has strong corrosion resistance. Please contact us today and we will help you with all your plating needs. Nickel undercoats should be applied for silver plating on copper and copper alloys. Link to Active This link will always route to the current Active version of the standard.
Historical Version s – view previous versions of standard. This specification establishes the requirements for electrodeposited silver coatings that may be mat, bright, or semibright, and b70 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.

ASTM B700 Silver Plating Standard
Silver plating is a highly electric conductive and has outstanding properties for contacts and connectors. 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 as post-plating embrittlement relief. Allow our asttm at Accurate Precision Plating to lower your cost on your next electroplating application, while still meeting your complex requirements. This abstract is a brief summary of the referenced standard.
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. Corrosion Protection A nickel undercoat with silver plating can be used for applications where corrosion protection is important. Medical Device Silver Plating.
Silver plating is best used for applications in asstm 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 ashm of electronic applications.
Our extensive quality control measures throughout production include non-destructive testing in accordance with ASTM to measure the thickness of the coating. Whether you have low or high volume plating requirements, our experts can aetm you through the plating process required of your industry.
Coatings shall be sampled, tested, and conform accordingly to specified requirements as to nature, purity, appearance, defects, 7b00, 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.
Tarnish Astn 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. Some of these applications include:. 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.
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. This standard does not purport to address the safety concerns, if any, associated with its use.
It also offers excellent corrosion resistance and solderability.

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. Coatings shall be classified into types according to minimum purity, grade according to surface appearance bright, semibright, or matand class according to whether any surface treatment has been applied.
The adhesions of the silver plating can be adversely affected due to a weak copper and silver inter-metallic layer.
