ASTM B Cadmium plating thickness can be adjusted, making it ideal for both large and small projects. Nonmagnetic Coatings on Magnetic Basis Metals. Chromating will retard or prevent the formation of white corrosion products on surfaces exposed to various environmental conditions as well as delay the appearance of corrosion from the basis metal.
Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access asym trade, and build consumer confidence.
This abstract is a brief summary of the referenced standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The cadmium coating shall be sufficiently adherent to the basis metal to pass the tests. The as-deposited coating Type I is useful for the lowest cost protection zstm a mild or noncorrosive environment where early formation of white corrosion products is not detrimental or harmful to the function of a component. It can also be electrodeposited on aluminum, brass, beryllium copper, copper, nickel, and powder metallurgy parts. Link to Active This link will always route to the current Active b7666 of the standard.
Electrodeposited cadmium coatings shall be classified on the basis of thickness as Class 25, 12, 8, and 5. The coating shall be essentially pure cadmium produced by electrodeposition usually from an alkaline cyanide solution. 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.

Cadmium shall be deposited directly on the basis metal part without an undercoat of another metal except when the part is either stainless steel or aluminum and its alloys. Cadmium-coated steel parts have a lower adtm contact resistance than zinc-coated steel. This abstract is a brief summary of the referenced standard. B Terminology Relating to Electroplating.

The lubricity of cadmium plating is used on springs for doors and latches and for weaving machinery operating in high humidity. This specification covers the requirements for electrodeposited cadmium coatings on products of iron, steel, and other metals. Nails, Spikes, and Staples. The lubricity of cadmium plating is sstm on springs for doors and latches and for weaving machinery operating in high humidity. The prime purpose of the supplementary chromate finishes Types II and III on the electroplated cadmium is to increase corrosion resistance.
Chromating will retard or prevent the formation of white corrosion products on surfaces exposed to various environmental conditions as well as delay the appearance of corrosion from the basis metal.
Link to Active This link will always route to the current Active version of the standard. The basis metal shall be subjected to such cleaning procedures as necessary to ensure a surface satisfactory for subsequent electroplating. This allows for proper functioning during corrosive exposure of sstm parts, threaded assemblies, valves, and delicate mechanisms without jamming with debris.
The as-deposited coating Type I is useful for the lowest cost protection in a mild or noncorrosive environment where early formation of white corrosion products is not detrimental or harmful to the function of a component. Click here to download full list of books.
ASTM B Cadmium Plating | Keystone Finishing
Historical Version s – b766 previous versions of standard. Corrosion products formed on cadmium are tightly adherent. Print 1 2 3 4 5 zstm sstarting from page current page. Cadmium-coated steel parts have a lower electrical contact resistance than zinc-coated steel. 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.
Asmt plating shall be applied after all basis metal heat treatments and mechanical operations. At Keystone Corporation, our baking aztm prevents the occurrence of hydrogen embrittlement, helping ensure a more durable product, and our electrodeposited method improves the bonding of paint and adhesion, allowing you the option of an attractive final finish or allowing for the application of sealants or chromates over the cadmium finish.
The as deposited coating Type I is useful for the lowest cost protection in a mild or noncorrosive environment where early formation of white corrosion products is not detrimental or harmful to the function of a component.
ASTM B766 Cadmium Plating
The coating shall be essentially pure cadmium produced by electrodeposition usually from an alkaline cyanide solution. Are you sure you want to empty the cart? Nonmagnetic Coatings on Magnetic Basis Metals. The lubricity of cadmium plating is used on springs for doors and latches and for weaving machinery operating in high humidity. Undercutting of threads on fastener parts is not necessary as the cadmium coating has a low coefficient of friction that reduces the tightening torque required and allows repetitive dismantling.
The prime purpose of the supplementary chromate finishes Types II and III on the electroplated cadmium is to increase corrosion resistance. The as-deposited coating Type I is useful for the lowest cost protection in a mild or noncorrosive environment where early formation of white corrosion products is not detrimental or harmful to the function of a component.
