Macor distributors

A number of Macor distributors are online, though, annoyingly, Corning's website does not list the links. I compiled what I could - hope that it turns out to be useful to someone else out there. Note that Leed Plastics has been purchased by PlastiFab.

Macor - machineable glass ceramic

Macor is a machineable glass ceramic produced by Corning. It has a DC volume resistivity at 25 C exceeding 1016 ohm-cm. That puts it in the same category as sapphire in terms of resistivity. It can be machined with ordinary metal tools and requires no firing after machining. There are only eight distributors in North America. Astro Met in Ohio has a price list posted online. It ain't cheap. 1/16" is probably the right thickness for my application. A 3"x3" block cost $51. The closest one to me is San Jose Delta.
