Oct 07, 2008 2005. A. Sheasby and Pinner in their book, 6th edition, list LM6 (with 12% silicon, you anodize aluminum not silicon) as moderate for protective anodizing, unsuitable for anodize and dye, and unsuitable for bright clear anodizing. They do not list any die cast alloys as excellent for anodize, dying, or clear. Come back for more info on the process for the best you can do on die cast.

Die casting aluminum alloy normally contain high amount of silicon so anodizing turn to dark gray and it is impossible to get clear anodizing.As increase of silicon,anodizing will change from gray colour to black colour gradually.Therefore,die casting aluminum is not suitable to anodizing. Common die casting aluminum include mainly three ...
Mar 02, 2021 This is opposite of what you need to do. Do not alkaline etch castings. For die castings, deox in 50% commercial nitric acid with 1 pound per gallon ammonium bifluoride, takes about 20 seconds, rinse twice and go to anodizing quickly. ONLY fluoride will remove all or part of the exposed silicon and show more aluminum area.

Dec 17, 2019 Aluminum castings will commonly have a dull appearance after plating due to porosity, mold contaminates, and alloying elements. There are two classes of anodizing: Class 1 and Class 2. Class 1 is a non-dyed, clear (natural) color. Class 2 is dyed, and a color must be specified. Typical thickness is .00005 to .0005.
It is inferior in this respect to LM6 but can be improved by anodic treatment. Anodizing. LM2 can be anodically treated to give a protective surface of a dark grey colour. The surfaces of die castings, however, are not generally suitable for decorative anodizing. Casting Characteristics. FLUIDITY - Good, can be cast easily into thin and ...
Die casting alloys are normally non-ferrous alloys. Non-ferrous means no iron. Non-ferrous alloys are a mixture of two or more metals that do not contain a significant amount of iron or steel. Aluminum die casting alloys are among the most lightweight structural metals and a majority of die castings produced worldwide are made from aluminum alloys.
