Hi George, 7075-T6 is pretty much the most popular aluminium alloy in the aerospace/high tech business, and it’s roughly 50% stronger than most common “aerograde” alloys used in flashlights, which are 6061-T6 and 6063-T6. Strength wise you really don’t need it, but personally I just think it is cool. As far as I know there are only a few flashlights made from 7075-T6, which are the Thrunite Catapult V2, V3 (not V5) and Tiablo lights. Although a manufacturer states it’s 7075-T6, you don’t have certainty that it actually is so though… Most common problem with 7075-T6 (for flashlights) is that anodising is much more difficult than with 6000 series aluminium.
G'Day hIKARInoob,
Thank you Very Much for your reply.
Yes, it is as I expected and knew. But I thought I may have not considered some other aspect.
Best Regards,
George
Aerospace grade, woohoo
Anyway, all of it and it's alloy's have their own particular strengths and weaknesses. The weakest of them all (pure aluminium) is also the strongest, in one particular application. Corrosion resistance.
2024 in various tempers (the T designation) is, in my experience, the most used alloy in aircraft structures because of its particular combination of strengths. It's durable, workable, somewhat corrosion resistant, has a good balance of mechanical strengths all while being fairly lightweight. It's not the go to alloy for everything though.
There are many different alloy's used in aircraft construction and 6000 series isn't all that common. Basically just stuff that needs to be weldable (there are exceptions)(usually non structural).
7075 T6.... Hmm I hate it, it's tough as $&#+. It's hard to bend, shape, drill, sand, grind, scratch or dent. (Of course I'm speaking in terms of aluminium. It's not like it's 316 stainless or something).
Sounds like a great material to use for flashlight making huh
The thing is that with 7075 T6 the metal is much HARDER than 2024 or 6061 even with the same temper designation (T6).
Thats great for flashlights because you can have super smooth bare metal threads (as long as their within tolerance) that won't easily gall and a bare metal finish that's way more resistant to scratches and gouges. I'd say 20 times more resistant than what's seen in everyday budget lights.
If your gonna use aluminium to make a flashlight, then 7075 T6 is almost as good as it gets.
G'Day RotorHead64,
Thank you Very Much for the info. Greatly Appreciated.
Best Regards,
George

I like the look of this light, but I don’t want the cigar grip. Is the cigar grip ring removable? If so, can we see a pic of the light with the cigar ring removed? If it’s not removable, is there a good reason why not? Thanks!

Isn’t that why the bezel is reversible?
…although I must admit that I might foybezel it too. :innocent:
, I do like the design including the cigar grip but the monstrous bezel is wasted on me. Hmm, perhaps I can foybezel it?….
