Lodestone 4825 Titanіum magnet and Lodestone 5830 Titanіum magnet.
They both look to be bigger then the Titan. First I’ve heard of the company, so I haven’t got much to add.
Hah that didn’t take long… Thread incoming…

The Titan is 4.5mm × 2.8mm, and the 4825 is 4.8mm × 2.5mm.
So, they are really comparable, but since the 4825 is not as tall, mine doesn’t rotate around itself in its pocket constantly like the Titan did, which is a plus for me.

given your sanding photos, I think the walls on the sides are much thicker to accommodate the sealing process?

Yup, I haven’t measured it precisely yet, but on the side, it’s about 0.4mm—0.2mm welded and another 0.2mm unwelded.
From top to bottom, the wall thickness is around 0.2–0.25mm.
So that GIF isn’t 100% accurate.
Also, the chamfers in the GIF are just estimated.

Given this is now here, let me paste a part of the DTclub announcement for context:
As you might know if you’re hanging out on discord, our biohacking wizard Merlin 
was able to source some awesome new titanium magnets but hasn’t had the means to make them widely available so far. So we’ve decided to collab in order to bring together the funds and infrastructure to make them available to everyone.
Today we’re extremely excited to announce:
Biohacking – Abyss Walker
a subsection of my e-shop dedicated to magnets and future Lodestones!
We currently have two magnet sizes in stock:
the Lodestone 4825 a 4.82.5mm one, comparable to the titan
a slightly bigger Lodestone 5830 5.83mm for more strength.

On the page, am I understanding this correctly, that it is implied that you can have the magnets run through an autoclave? I thought that was a no-no because heat.

These are not neodymium magnets. They’re a special higher temperature type. They’re not as powerful but will withstand temperatures above an autoclave. It also allows them to be laser welded in to their case, as opposed to the titan which had a magnetic blank inserted into the case, welded shut, then magnetized after (the heat from welding would damage the magnets otherwise)

Interesting! Thanks!

I couldn’t say it better myself.
May I add that thanks to thinner titanium walls they retain roughly the same magnetic strength as a titan by having more magnetic mass.
Possibly stronger?

Based on the readings @amal took, the one comparable to the Titan’s size was on par in field strength. The larger one is most likely stronger.

That was my intuition, that’s why I’m not sure about those calculations.
I have a pro gauss meter in my stuff so I’ll make sure to characterize everything as well. I’m curious about the slightly rusty sense52 I just took out.

Just out of curiosity, does anyone know why they’re saying not to use EO gas sterilization, is it because of humidity or does the gas react with titanium in some way?

I’m not really sure but my hunch is that the material they are coated with absorbs the gas and eo gas has a problem with residual toxin left on the devices. Normal processing requires many flush cycles to clear it completely and some material will just not let go of it very well, especially porous material. The coating on the magnet is designed to improve adhesion so it’s definitely porous.
Discussion of that material here;
