First of all, lets limit the discussion to aluminium or titanium bolts. I know that steel bolts are fit and forget, but hey, we are on the weight weenies forum after all. In addition, they must come in black and have a nice finish. I suspect the black requirement takes most of the titanium bolts out of consideration. Finally, they must be intended for 3-speed cranksets, in this case a THM Clavicula.

I got some pretty nice black Ti bolts for my brake calipers from R2. What's the problem with black Ti bolts?

No problem, just that black ti bolts are not that common, especially when compared to aluminium ones. Additionally, is the added weight of ti worth it in this application?

Aluminum is fine for chainring bolts, except maybe on a tandem. Alum is lighter by about 1/3 than Ti. Alum is easier to get in colors.
For certain parts stiffer is more important than lighter.

Aluminium, I use Truvitiv as they come with a 5mm/6mm Allen fitting for the male/female rather than the silly screwdriver slot, easy to get, fairly light (19g for a set of 4 for 2 rings) and fairly cheap.

if you are in UK, check out the Onza aluminium chain ring bolts on ebay - they have Torx socket so more robust than hex socket.

nothing wrong with with using alloy bolts - top of the range Shimano XTR chainset have them.

Alu for many many km. Mine came from Toronto Cycles as part of a very large order switching over to all Alu/ Ti bolts. Can't fault them when super reliable and 6g for 4 bolts (1x10)

I have best luck with original Shimano alu. bolts(came with xtr-970 crankset) and Extralite Extrabolts. No problems whatsoever.

I cannot recomend KCNC or Tiso.
