Atomic Alloys offers through, case, and induction hardening heat-treating services. Through hardening is perfect for metals that need to be tough but won't experience high-impact scenarios and refers to the process of rapid quenching steel alloys for an overall increased hardness. Case hardening is best used on metal products that need a layer of surface hardness while remaining soft on the inside by toughening the surface through flame hardening. This can also be done through induction hardening, but this is best for individual parts rather than larger batches.
Mechanical plating is a galvanization process in which parts are tumbled inside a drum with zinc powder to cold-weld a uniform coating. The pros of this process are that it eliminates hydrogen embrittlement, can plate the metal without the need for impregnation, and can act as a cadmium replacement. Additionally, other coatings can be applied to meet specific requirements, such as trivalent passivates.
Zinc phosphating occurs when the process solution comes into contact with the metal substrate, forming a crystallized protective layer of insoluble zinc, making threaded parts resistant to corrosion and galling. Additionally, paints and other trivalent passivates are more easily bonded because zinc phosphate is naturally porous. Here at Atomic Alloys, our zinc phosphate coating is available in heavy, medium, and fine grain, depending on how resistant to corrosion the product needs to be.
ArmorGalv Thermal Diffusion Coating is an industrial coating service that we specialize in. It is a sherardizing process, a specific subform of galvanizing, used on ferrous metal surfaces. The advantages of sherardizing are that it completely eliminates hydrogen embrittlement, can accept other coatings, and won't deposit acid around welded areas, all while being highly corrosion resistant. Additionally, ArmorGalv can be applied to nails (known as ArmorNail) used in nonindustrial fields like residential construction. It's designed to protect the fasteners that secure your roofs, patios, and decks from structural failure from extreme weather or exposure.
Electroplating is a broader form of galvanization that allows for the deposit of any suitable metal onto an object, as opposed to using strict galvanization, which applies zinc onto the surface of ferrous metals. Our electroplating services are also RoHS, REACH, and Prop 65 compliant, meaning dangerous chemicals like cadmium, lead, mercury, and phthalates are not used in order to reduce exposure and protect drinking water.
Atomic Alloys offer barrel zinc and barrel zinc nickel industrial coating services that plate small parts and fasteners in a cost-effective manner. However, not only can our zinc plating be color customized, but it can also meet the high standards required for automotive and industrial parts. Barrel zinc nickel plating is the same process as barrel zinc plating, but small parts and fasteners are coated in a zinc-nickel alloy that is 10 times more corrosion resistant than pure zinc. This zinc-nickel alloy can also be color customized while meeting automotive and industrial part standards.
