Black anodized (Type 2,Grade 2)

-----

Dear Sirs,
Here we meet the question about "black anodized (Type 2,Grade 2)"
We don't know what kind of "black anodized (Type 2,Grade 2)"
Hot or cold? This black anodizing is hard black anodizing? or others?
Thanks in advance for your help.

Hello Wangjun. This probably is referring to MIL-A-8625 / MIL-PRF-8625 [⇦ this spec on DLA] or AMSA8625 type II conventional (68-72 deg F.) sulfuric acid anodizing, dyed black. Try to get a copy of the spec, or clarification from your customer; good luck with it.

P.S. to the readers: This inquiry developed into a political debate about outsourcing, which I confess to starting. If you wish to see that thread or express an opinion, it's now an editorial. If you don't like such debates, stay in this Hotline-letters area and don't follow the link. You've been warned.
