SMM and others - an analysis
I'm working on an analysis of some magnets. It isn't complete, but I think it will answer a number of the questions that have been posted recently. I'll update y'all with more info on the SMM results later. Here's a link:

Basically, it's no trade secret. I was at first really critical towards the SMM magnet.. but having found the additional layer of metal I'm hopeful. We may have a god damn 10 dollar biocompatible n52. We'll see.
For those asking, yes. I'm willing to make another batch of pellucids magnets. I want to point out though that the HWT magnet has gone down considerably in price. I think it's 60 bucks right now? That about what it costs me to make the ones I do.
Thanks, Cassox. I look forward to seeing your notes. I'd definitely recommend diamond paste polishing the SMM magnets. I made 4, and have left the 3 spares in saline to monitor. Minor editorial note: "The claim by SMM to be an N52 is most likely false.". I believe you meant "N55" there.
Cheers
TiN is titanium nitride, not the element tin (Sn).
Hey but atleast now we can get cheap tin "n55" magnets!
The SMM rep had no more info today. They said they only have the NiCuNi then double TiN. He said maybe there was a chance you didn't completely scrape all of the TiN off. They didn't have much info past that.
Interesting. Did he have any information regarding the scorching?
It's possible there's some technical explanation that escapes me. For example, welding of titanium requires gas shielding because when the outermost layer is exposed to air it forms an oxide layer with different characteristics.
Coating technology is weird. Maybe the initial layers laid down have different mechanical characteristics then the rest. I don't know. I'll be back at the lab tomorrow and have updates.
Magnet Analysis Followup and Other Fun
For those interested, there's a short follow up on the SMM magnet tests and a pic of the phosphorescent magnet implants I've been working on.
Are these the phosphorescent resin ones, or did you end up doing something different? You mentioned the resin was really brittle.
