Well, not really. The main PROCESS differences between a type 2 (cosmetic)and type 3 (full hardcoat) anodize are:Anodizing is not particularly durable. It is only fractions of thousands of an inch thick and is not much harder than the base metal. Hard coat anodizing is another process entirely.
Not exactly. I work for a cookware company. Yes, the expensive black anodized stuff. Anodized alumunum can be deep black, It's just a function of the time in the acid bath and the current used.Archer said:
You are quite right about the durability aspect, however. A true class 3 hardcoat anodize job is worlds apart from a cosmetic anodize. (Hint- if it is deep black or any color other than an olive gray it is NOT a class 3 anodize).
