It can also be electrodeposited on aluminum, brass, beryllium copper, copper, nickel, and powder metallurgy parts. The coating shall be essentially pure cadmium produced by electrodeposition usually b76 an alkaline cyanide solution. The cadmium coating shall be sufficiently adherent to the basis metal to pass the tests.

ASTM B – 86() – Standard Specification for Electrodeposited Coatings of Cadmium

The thickness of electrodeposited cadmium coatings shall be determined by the applicable test methods. The plating shall be applied after all basis metal heat treatments and mechanical operations. Nonmagnetic Coatings on Magnetic Basis Metals.

The thickness of the coating everywhere on the significant surface shall conform to the requirements of the specified class. The thickness of electrodeposited cadmium coatings shall be determined by the applicable test methods.

The supplementary Type II chromate film shall be adherent, nonpowdery, and abrasion resistant. Remember me for one month. Cadmium-coated steel parts have a lower electrical contact resistance than zinc-coated steel.

At Keystone Corporation, our baking process 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.

Cadmium plating is applied in the automotive, aerospace, and military fields, beneficial for its reliability, consistent coverage, and cost efficiency.

This abstract is a brief summary of the referenced standard. Corrosion products formed on cadmium are tightly adherent. This allows for proper functioning during corrosive exposure of moving parts, threaded assemblies, valves, and delicate mechanisms without jamming with debris. 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.

ASTM B Cadmium plating thickness can be adjusted, making it ideal for both large and small projects. Nonmagnetic Coatings on Magnetic Basis Metals.

ASTM-B, –

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. Our finish choices include: Cadmium-coated steel parts have a lower electrical contact resistance than zinc-coated steel.

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. It can also be electrodeposited on aluminum, brass, beryllium copper, copper, nickel, and powder metallurgy parts. Cadmium-coated steel parts have a lower electrical contact resistance than zinc-coated steel.

We look forward to speaking with you. The lubricity of cadmium plating is used on atsm for doors and latches and for weaving machinery operating in high humidity.

ASTM B766 – 86(2015)

Are you sure you want to empty the cart? Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. 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.
