Is CMG Ultra G HA?

Yes, infinity ultr Gov is HA. It's the cheapest real HA light you can buy. a simple test is take a high quality knife and try to scratch the anodizing. Real HA will resist the knife, std color anodizing will easily scratch. Caution!!! test a area that you will not notice. knife scratches don't come out.

I understand the question.
The Ultra-G doesn't look like natural HA III. It is a lighter green. It doesn't have color inconsistencies, and the head matches the body. I bought 4 of them (only 1 for myself), and they are identical. Now I know why some people call the Arc HA III's gray rather than green.
I also have a regular Infinity with a black finish. Except for the color, it looks identical to the Ultra-G.
They both look real nice, and I don't think the finish is going to wear off of either of them, but I doubt that the Ultra-G is HA III.
And NO, I'm not going to use a knife to see if they can be scratched. "Test an area that you will not notice" - right - like where would that be?

This debate has been goin' on forever. The Ultra G is SUPPOSED to be HA III, but the consensus seems to be that it may not be . . . or if it is, it isn't as tough as other companies' HA III. It still scratches relatively easily.
What we do know is that it is a darker green than the standard Ultra and that it is still a great all around light and a great value.
Cheers,
Dave

The infinity Ultra Gov model was spec'd to meet the US Gov's spec's for Hard Anodizing. HA 3 has a hardness up to 67 rockwell. most quality knives have a rockwell of 58-60. Assuming your ultra G meets HA spec's. I'd like to see you scratch it. You may wear the HA off in places from being rubbed against keys etc. Also if you drop it on concrete, you will go thru the HA layer into the soft base.
You can also have anodizing be HA but not meet Gov spec's An example is some of the light HA Arc twistys. Those you will scratch. Yes there are not many good scratch testing places on a ultra. I just used the main body. Please note HA will be less dense in certain places due to less current draw. example the lanyard hole inside will be soft compared to the body.
The scratch test is the easiest way to test for HA. You don't want to know what the official testing methods are.

What I was meaning is that I think it has been a topic of debate whether the Ultra G really meets HA III specs. Or at least the same HA III performance as lights from Arc and SureFire. Like I said, it it SUPPOSED to be (i.e. is "spec'd" to be) HA III, but in my personal real-world experience, the Ultra G's finish does scratch more easily than that spec would indicate.
And despite that, I think most of us really like our Ultra G's, especially considering their reasonable price.

i was under the impression that only County Comm's Government models were HA3..
ryan, i think there might be some confusion regarding the terminology here...
type II anodizing is the type of anodizing you usually get on cheaper lights such as maglites and some surefires. if i'm not mistaken the "natural" colour of type II anodizing is clear, which is why it is usually dyed a certain colour. its tougher than bare aluminium, but it wears off with use.
type III anodizing is different from type II anodizing, in that the voltage supplied to the parts in the acid bath is higher, and the anodizing solution is kept at a lower temperature. the resulting "natural" colour of type III anodizing is usually a dark green/grey/brown, and it varies with the alloy of the metal used, and various other variables i'm not aware of. type III anodizing is much harder than type II anodizing, and thus more resistant to wear. another name for type III anodizing is hard-anodizing.
HA is HA or type III anodizing, and type II is type II. therefore when referring to a part as being hard anodized, it means its anodized in type III anodizing. regular anodizing is type II anodize. there's no such thing as HA II. the term "HA III" though not incorrect, is redundant...its like referring to an M9 service pistol as a "Beretta 92F M9". /ubbthreads/images/graemlins/smile.gif
back on-topic: the regular CMG infinity and infinity ultra is anodized with type II anodizing, i.e. the same type of coating you get on maglites. the CMG inifinity ultra government model sold by countycomm is supposed to be anodized in type III anodize, or HA /ubbthreads/images/graemlins/grin.gif

so i was right? /ubbthreads/images/graemlins/wink.gif
well...yea /ubbthreads/images/graemlins/grin.gif its just that i'd noticed in many other threads that people seemed to be confused over the terminology, and it sounded like you might have been too, hence my previous post. it was directed more at anyone who might read this thread, just that it was your post that sparked off my initial reply /ubbthreads/images/graemlins/wink.gif

It was helpful to me.
So are all ArcAAAs HA?
So are all ArcAAAs HA?
puyo: the first few runs of the arc AAA was made in black type II anodizing. later runs up till v3.1 were made in black type III anodizing (HA). after that all arc AAAs were made in natural type III anodizing. notable exceptions would be the blue and red CPF arc AAAs, which were also hard anodized /ubbthreads/images/graemlins/smile.gif
Chamenos is 100%!
Blindedbythelite is correct. Ultra Gov model is the only ultra that's HA. It is the cheapest light that is true HA. A real bargain!!! I don't know if Countycomm is the only source.
Destructive testing is the only way to see if hard anodizing exists on a finished product. If you have access to the part prior to anodizing then you can do non-destructive testing by measuring the part. Usually it measured in mils or thousands of in. 3 mils is considered a good hard anodize film. Someone correct me if I'm wrong, I believe 3 mils is Surefire's spec's.
Sorry about boring everyone with another repeat. I've posted this same info several times now. I've posted an extensive scratch testing methology and why.

That's what you say. But repeating the same statement doesn't make it any more accurate.
**** It doesn't look like HA III. *****
Do you have any evidence for your view other than County Comm's claims? We can all read what they say, and we have our doubts that they are correct.
There wouldn't be any need for debate if someone had proof that it's HA III. Until I see some proof, I will continue to doubt it, and the question remains valid.

Lightscene, I didn't just state it's HA. But laid out the reasons why I came to that conclusion, the testing methodologies and how you can duplicate testing (proof)on your own.
Sorry about the repeat: I used to do std anodizing, color anodizing, hard anodizing and all types of production plating.

Tested my CMG Ultra G just above the O ring /ubbthreads/images/graemlins/smile.gif
& My knife just slid off it /ubbthreads/images/graemlins/smile.gifvery hard, So it good enough for me /ubbthreads/images/graemlins/wink.gif
My Mag light scratches very easy /ubbthreads/images/graemlins/frown.gif

Maybe I misunderstood you. Have you actually tested the Ultra-G yourself?

Yes I have done the scratch test on my infinity ultra G, which is now sold to a buddy. There is no way I would make a claim without first testing it myself.
