Nickel Plating Aluminum Specification

Electroless nickel plating specifications the two most common electroless nickel plating services certified by advanced plating technologies are mil c 26074 astm b733 and ams 2404.
Nickel plating aluminum specification. The nickel plating shall have columnarcrystalline structure before anneating. Sulfamate nickel coating specifications set the requirements for plating steel aluminum and copper substrates as well as the standards for cleaning and the best underplating processes to prevent degradation of the base material. Apt also can certify electroless nickel plating services to iso 4527 and ams 2405 as well as most company specific electroless nickel specifications. Thus hardness can range from 150 1500 vickers.
Electroless nickel plating on aluminum comply with mil c 26074 ams c 26074 astm b733 and ams 2404 electroless nickel plating aluminum produces very uniform hard and lubricious coatings without an externally applied electric current. If you are involved with nickel plating or specify nickel plating you should be familiar with this specification. Can be similar in color to. Nickel deposits containing no additives.
Astm b733 also specifies five 5 types of electroless nickel plating. Our series 200 electroless nickel plating coatings are applied via a time controlled deposition process which allows us to specify a wide range of thicknesses and hold tight tolerances. Nickel plating services nickel plating specifications the two most common nickel plating services certified by advanced plating technologies are qq n 290 astm b689. Nickel deposits containing various types of additives.
While aluminum features a high strength to weight ratio it is softer than many other metals. Color will vary with alloy aluminum with low alloying elements will show practically no color change best coating on aluminium for dyeing. A nickel plated coating will increase the hardness of the aluminum alloy substrate and increase corrosion resistance. Apt can also certify nickel plating services to iso 1458 ams 2423 and ams 2403 well as most company specific nickel specifications.
Nickel can be deposited soft or hard dull or bright depending upon process used and conditions employed in plating. Service condition is based on the thickness starting with sc0 for minimum service requirements and continuing up to sc4 for severe service requirements. Classes grades of sulfamate nickel plating. The astm specification also discusses testing methods and sampling requirements.
Within the astm b733 electroless nickel plating specification there is an additional category known as service condition. Nickel deposits containing dispersed submicron particles.
