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. 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 asttm bonding, sound reproduction applications, electrical applications that require spectral reflectivity, and other types of electronic applications.
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.
Nickel undercoats should be applied for silver plating on copper and copper alloys. This standard does not purport to address the safety concerns, if b70, associated with its use.
ASTM B700 Silver Plating 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. Coatings shall undergo preplating operations such as stress relief treatment, strike, and underplating, as well as post-plating embrittlement relief.
Go to B00 Go to Content. Corrosion Protection A nickel undercoat with silver plating can be used for applications where corrosion protection is important. Nonmagnetic Coatings on Magnetic Basis Metals. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. ASTM does not give any warranty express or implied or make any astn that the contents of this abstract are accurate, complete or up to date.
At APP we constantly strive to provide excellent steel silver plating services at a reasonable price. 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.
Allow our experts at Accurate Precision Plating to lower your cost on your next electroplating application, while still meeting your complex requirements. 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.

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 asttm.
Some of these applications include: Our state-of-the-art equipment allows us to meet tolerances of 25 micro inches. Our extensive quality control measures throughout production include non-destructive testing in ast, with ASTM to measure the thickness of the coating.
