Aluminum Anodizing - How To Information | eHow.comAnodizing is an electrochemical process used in converting dull metal surfaces into attractive, corrosion free and durable finishes.

Anodizing ... the finish of choiceEnvironmentally safe aluminum anodizing produces a durable, aesthetically pleasing finish for endless design applications.  0.5µ-7.6µ (microns) 4.18 mg/cm22.32 g/cm3 2.40 mg/cm22.32 g/cm3 A.Q.** Types Non-A.Q.** Types Finishing advice: for 5005-keep silicon<0.1% and magnesium between 0.7% and 0.9%; watch for oxide streaks; 5005 used extensively for architectural Finishing advice: matte-iron>0.2%; bright-iron<0.1%; 6063 best match for 5005; 6463 best for chemical brightening ** A.Q.

    • We have been having a problem with hardcoat anodizing of 7075-T651 aluminum. We're specifying type III hardcoat, clear/undyed. I know the vendor has been sealing our parts but I'm not sure by which method. Our print does not specify.The problem we're having is blotchy color. Our parts used to be greenish/gold that is common with hardcoated parts. At some point we asked the vendor to make the coating thicker, from 2 mils to 3 mils total. (We grind our parts flat after anodizing and were breaking through at 2mils.) The color of the parts changed to light gray with the thicker coating.Our most recent batch of parts came out gray, as usual. They were gray after grinding. At some point after we shipped the product they became mottled with the grey/gold finish in places.

It is, however, much lighter and softer than Stainless and Carbon Steel. To prevent the dull appearance that results from the oxidation of the outer layer, Aluminum can be either clear or color anodized after perforating . Unlike paint or powder coating, anodize film is built from the aluminum itself and takes on a translucent appearance. The alloys listed below are categorized into two types, non-heat-treatable and heat-treatable.This commercially pure, low-strength alloy has excellent corrosion resistance and satisfactory anodizing and coating finishes. It is unmatched by any other commercial aluminum alloy in workability.The most widely used general-purpose alloy because of its good corrosion resistance, moderate strength, formability, and weldability.

OLD MIG WELD TECHNOLOGY WITH PROCESS EXPERTISE, OFTEN PROVES TO BE MORE BENEFICIAL THAN NEW ROBOT AND WELD EQUIPMENT TECHNOLOGY WITHOUT WELD PROCESS EXPERTISE. In the nineteen nineties, Ed set the first multi-robot robot line in North America, to weld a large aluminum application as seen with ABB robots welding aluminum golf cart frames, (above photo). Ten years later, in contrast to more than 80% of the robots in the auto industry welding "carbon steel" parts, the four robots welding aluminum frames achieved much greater robot production efficiency, less down time and less weld rework.
