Specs for Black Anodizing of 6061-T6 Aluminum
2005
We require a Black Hardtuf X20 Anodize finish per MIL-A-63576 A (or equivalent) on some of our parts. Can you tell me if MIL-A-8625 / MIL-PRF-8625 [on DLA]F is equivalent to this finish?

2005 Black Hardtuf X20 is a proprietary process that would take place AFTER the parts are Hard Anodized. metal finishing - San Jose, California MIL-A-63576A specifies a hardcoat per MIL-A-8625 (Type III, Class 1) *Emphasis on Type and Class* with an additional PTFE post treatment. So no, they are not equivalent. Companies who supply coatings to this specification, using a variety of trade names, use different techniques and methods to apply the PTFE post treatments. So Luke Engineering's product, Lukon 24, and others may not be exactly equivalent either. Chris Jurey, Past-President IHAALuke Engineering & Mfg. Co. Inc.  Wadsworth, Ohio  2005 |
