About
The TMF Series includes copper foil straps (CuFS, ETP/C110 or OFHC/C101 up to 6N ultra-purity) and aluminum foil straps (AlFS, 1100/1050 alloy up to 5N purity). ETP copper is recommended above 40 K while OFHC copper is preferred below 40 K; higher-purity aluminum becomes advantageous below 70 K, and aluminum offers roughly one-third the density of copper for mass-sensitive applications. Foil width, cross-section, thickness, and length (up to several feet) are configurable to the application, with optional gold coating available for thermal control and oxidation mitigation.
