Cryogenic Structural Alloys

High-strength alloys that stay tough at the temperature of superconducting magnets.

Requirement

Cryogenic toughness

Magnet cases and cold-mass structure use alloys that keep high strength and toughness at cryogenic temperatures — austenitic stainless steels and specialised nickel alloys — to contain immense Lorentz forces. Their fatigue behaviour is the binding magnet gate.

Material choice here is inseparable from the magnet's structural integrity.
