Due to its good wear resistance, a hard-coated aluminium material can replace expensive wear-resistant steel. The same applies to the replacement of expensive corrosion-resistant materials. Potential applications are where contact corrosion should be prevented, anti-friction properties improved, electrical or heat insulation increased.
The density of aluminium alloys is about one third of the value of conventional ferrous and non-ferrous metals. By switching from steel or brass to aluminium materials, inertia forces of high-speed machine parts can be substantially reduced. This results in new constructional options and savings in energy costs. The required surface durability is achieved by using HART-COAT®.
Examples of HART-COAT® hard-anodised components are: spacers, iron soleplates, surgical instruments, damping chambers, nozzles, guide cylinders, housings, fixings, levers, heating plates, insulating bolts, camera parts, rocker arms, clamps, pistons, clutch parts, bearing rollers, bearing shells , baffles, guide rollers, mounting plates, cam discs, pneumatic and hydraulic cylinders, rollers, spools, transport levers, valves, compressor wheels, gears wheels and racks, centrifuges, cylinder heads, cylinder tubes.
The industrial sectors using HART-COAT®-finished components include, amongst others: gauge construction, automotive, mining, office technology, data technology, energy technology, household appliance industry, food industry, mechanical engineering, medical device construction, measurement technology, pharmaceutical industry, reactor technology, control technology, defence technology.
