Though they are used for different applications, both cobalt-chrome and cobalt 21 are high-strength, high-stability alloys. Because of the different applications in which they are used, though, both of these alloys benefit from a finishing procedure that increases both strength and longevity. Cobalt 21 and cobalt-chrome electropolishing services eliminate surface imperfections, including contamination, making these parts safer and more suitable for their typical uses.
Cobalt-chrome is frequently used for medical and orthodontic implants, which must be free of surface-level contamination and other imperfections. Surface defects like micro cracks can harbor bacteria and moisture, leading to corrosion. Similarly, contaminants may be embedded in the surface material after machining, which can also compromise a part’s biocompatibility. Cobalt-chrome electropolishing services strip away the surface metal from a part, eliminating both surface imperfections like micro cracks and contaminants embedded in the surface material.
A similarly high-strength alloy, cobalt 21 is frequently used for parts such as high-pressure valves, mixer blades and turbine components. If parts like these are manufactured with surface imperfections, it can compromise how they function and lead to expensive part failure. Contamination embedded in the surface of a mixer blade from the machining or mechanical polishing process, can lead to corrosion after being exposed to harsh solvents and chemicals. In addition, the electropolishing improves the cleanability reducing costly production downtime.
Electropolishing treats metal parts by submerging them in an electrochemical bath, which removes a uniform amount of surface material. When that material is removed, it leaves behind a smooth. passive surface free of cracks, pits and embedded contaminants. This procedure is suited for a wide variety of industries and parts of various shapes and sizes.
From implantable devices to surgical instruments, electropolishing is a single-process treatment that results in biocompatible, safe and ultra clean parts.
We offer aerospace vendors and original equipment manufacturers our signature metal finishing services to increase fatigue-resistance for their metal parts, rendering them capable of withstanding the stress and corrosion that comes with long-term use.
Our strict adherence to industry standards ensures that pharmaceutical components are electropolished in accordance with ASTM B912 and ASME BPE specifications. These products are clean and smooth, corrosion resistant and contaminant free.
Corrosion resistance and microfinish improvement are essential for critical automotive parts, making electropolishing an increasingly beneficial option for automakers.
Our metal finishing services help increase corrosion resistance for these parts, and by removing the outermost layer of metal withelectropolishing the durability and longevity of these appliance components is increased.
Electropolishing materials for this industry eliminates the buildup of bacterial biofilms, as well as keeping the equipment free of contaminants like Salmonella. Electropolishing delivers the level of sanitation required by a number of regulatory agencies.
From robotics to mobile equipment, the uses of electropolishing in the hydraulics and pneumatics industry are many. By helping prevent premature part failure, electropolishing reduces downtime and increases the life cycle of these components.
Improving conductivity and performance is just one benefit electropolishing offers for electronics parts. The surface finish is improved by as much as 50%, removing imperfections from the material without material removal.
Even in a year of unprecedented manufacturing obstacles and supply chain bottlenecks, medical manufacturers have bigger challenges.
Electropolishing removes the recast layer created during electrical discharge machining (EDM), improving the fit, function, and finish of metal parts.
Among the most demanding surface finish requirements of any industry, the specifications, standards and quality assurance processes that cover components used by the semiconductor industry impose metal finishing criteria that leave nothing to chance.
