Hard Anno?

[GT]

What is the differnce bewteen regular anno and hard? Does anyone have pics of hard anno?

I believe hard anno is just a more intense process and the result is more tougher anno that can take more of a beating

but im not completly sure, I just picked that up somewhere

IIRC the back of the retro\x-valve is hard annodized.

that aint got nothin to do with no spellin. that there is grammer.

Go check out an AKA Viking or Excal... that is hard annodizing from a Military-Spec business. That **** never scratches. Compare that to something like Angel LCD annodizing... which scratches when you frikkin breath on it.

anno

The difference is in the depth of the annodization.

The process is the removal of aluminum and replacing it with
a substrate. This substrate is very hard. It does change the
dimensions of the aluminum but
only in thousanth's of an inch.

Hard anno is not as smooth or pretty. It is harder to get hard
anno glossy. Hard anno does last longer and takes more wear.

Your should talk... "your"?

All aluminum annodization is "hard annodized". The longer a piece is electricaly conductive in the solution at a given amperage, the greater the amount of oxide layer is grown on the surface of the aluminum. Its the oxide layer that provides the hardness in the annodizing process. Obviously, a thicker layer produces a harder more duable surface. Typically the anodize layer is formed at the rate of 0.0001" per 7 minutes. Most processes for small parts take about 15 min just to give you an idea of the average oxide thickness for most parts..

yeah

Athomas:

What I have experienced lately is that the same shop will do
either finish for you, the reaction time in bath is the
difference I think.

If you ask for a cosmetic anno most shops won't put as thick
a finish on, whereas the hard anno is thicker.
