Industries · Superconductors & Quantum
Below 4 Kelvin, every micron of surface finish matters.
Cryogenic and quantum-computing hardware operates at thermal and dimensional regimes most CNC shops never touch. Vacuum-grade OFHC copper, niobium-grade machining, surface finishes to 4 µin Ra for vacuum joining, outgassing-controlled materials. We build cryostat parts, SRF cavity hardware, magnet bobbins, and dilution-refrigerator components.

01 · Why cryogenic is different
Thermal contraction, vacuum integrity, surface chemistry.
Hardware that sits inside a dilution refrigerator at 10 millikelvin behaves nothing like room-temperature parts. Materials contract differentially. Vacuum integrity becomes load-bearing. Microscopic surface contaminants outgas and ruin experiments that took months to set up.
Working in this regime requires rigid material control (no leaded free-machining alloys, no oil-impregnated bronzes, no plastic), validated cleaning and packaging procedures, surface finishes tight enough to enable vacuum-joining, and tolerances that hold dimensional integrity through thermal cycling. The same discipline we built for aerospace and space programs maps directly — same materials, same metrology, same documentation chain.
