Jun 07, 2017 When hard anodizing, the best results are usually found with 6061 and 6082 alloys. 6063 is a favorite alloy for cosmetic work. Finally, 7000 series alloys use zinc as the alloying agent and they are considered very strong with a clear finish. These alloys are popular in the automotive industry.
Most aluminum alloys will build aluminum oxide in an anodizing tank, so the answer to this question depends on the anodizing process and the desired result. Copper containing 2000 series are generally the most difficult to anodize and 5000 or 6000 series are the easiest. SAF recommends 5005 aluminum alloy for sheet 6063 aluminum alloy for ...

Aug 01, 2004 In any case, anodizing of either of these alloys will give a rather dull gray appearance. If the silicon is not homogeneous, it wants to migrate to the metal surface and will appear as brownish, blotchy areas after anodizing. Anodizing should be done in a bath of 200–250 g/liter sulfuric acid at 70° F,voltage should not exceed 15 volts.
According to the 3003 aluminum properties, 3003 aluminum sheet can be anodized, but it is not recommended to do it because the effect is very poor. 3003 aluminum sheet is divided into cold-rolled aluminum plate and hot-rolled aluminum plate. For the anodizing, the hot-rolled 3003 aluminum sheet is much better than cold-rolled 300 aluminum sheet.
Jan 01, 1999 The correct alloy and temper for aluminum cathodes is vital, 6063 or 6101 alloys in the T-6 or T-5 condition are best. The overaged T-52 temper should never be used! Cathode material should be welded to an aluminum header bar using 5356 alloy welding wire.
