Ah, I thought that 6/4 was a tougher material, than say CP (commercially pure) which I believe was used in cheaper ti lights in the past...
I guess I just don't understand all the nuances!
Correct, I probably could've used better worlds to describe what I had in mind, I didn't want to confuse gunga by implying that CP Grade 1 is stronger than 6-4 Ti. Also readers should keep in mind that numbers that you are presenting are a 'min' numbers for those alloys so strong 23 grade can be stronger than weak grade 5 despite having lower minimums. My point was that the Grade of Ti does not correspond to strength (higher grade = stronger Ti), if you don't know what given grade is exactly you can't tell anything about it's strength ;) Also Ti 6-4 is one of the cheaper if not the cheapest alloy correctly produced (cheaper than weak Grade 1 Ti) and there is no reason why respected manufacturer like EagleTac would use anything different.No, you understood just fine. Ti-6Al-4V is vastly stronger than CP titanium. Per Carpenter, specified minimums are:
CP Grade 2: yield strength 40 ksi; barely more than ordinary 6061-T6 aluminum
CP Grade 4: 70 ksi; no more than high strength aerospace aluminum
Ti-6Al-4V, annealed: 120 ksi
Ti-6Al-4V, STA (solution treated and aged), 127-144 ksi
Ti-3Al-8V-6Cr-4Mo-4Zr, STA: 180 ksi
Ti-3Al-8V-6Cr-4Mo-4Zr, STA with cold drawing stage: 180-210 ksi
Titanium is just all over the place. There is a vast difference bewteen alloys and grades; even between different grades of CP. CP Grade 1 is ridiculously weak. It is only 25 ksi.
ya,,the d25a is not the brightest light but not bad either for aa.its great for indoors and bathroom runs in the middle of the night!!
LightJunction's stock numbers are declining as expected. the NeutralWhite T6 (D25A Ti Clicky) is already sold out.
Just got shipping notice from IG. D25C Ti Clicky on its way 1st class (free shipping is always best!)
