Abstract

Space Dynamics Laboratory (SDL) first developed thermal strap technology in 1994 when we designed, built, and tested the SABER instrument, which is still on orbit and has performed flawlessly since 2001. Since then, we have continued to pioneer solderless flexible thermal straps and supporting technologies.

SDL’s heritage thermal straps used aluminum 1145 foil, an extremely pure alloy that contains 99.45% aluminum content. Unfortunately, it is no longer readily procurable in the market. Aluminum 1235 is a very similar alloy with similar chemical composition and physical attributes, but more readily available than 1145.

This report documents the process and results in qualifying aluminum 1235 foil as a direct replacement to 1145.
