2024-T3 tube cracking when flaring
2024-T3 tube cracking when flaring
(OP)
I've already asked this in the aerospace forum, thought I'd try over here. I'm trying to single flare 1/4 and 3/8 OD .035 thick 2024-T3 tubing and I'm getting cracking. I think the problem is in the tube prep. Does anyone has a working process; cutting, filing, deburring, sandpaper grit?

The only times I've heard of cracking during flaring is when the tube end was cut using a tube cutting tool, the type of tool with a rolling cutter. That's because the tool work hardens the material at the end of the tube to some degree.
The way around this is to simply cut using a hack saw. There are special tools to clamp onto a tube which are used to guide a hack saw, I'd suggest using them. They clamp to the tube and have a slot for the hacksaw blade.
Deburr of course after using the saw. Hope that helps.
