... · °F) at room temperature to 420 J/kg · °C (0.10 Btu/lb · °F) at 90 °C (200 °F). The magnetic permeability of beryllium-copper is very close to unity, meaning that these alloys are nearly perfectly transparent to slowly varying magnetic fields. All beryllium-copper alloys and product forms have...
