Field notes
The homepage treats low-expansion machining as a process-control problem rather than simply a vendor search. It explains why roughing and finishing may need to be separated by stress relief, and distinguishes Invar 36 from Super Invar, Kovar, and Alloy 42 with typical expansion ranges, uses, and machining notes. A calculator runs locally in the browser using entered dimensions, temperature swing, and tolerance.
