electromagnetic radiation - Why does NASA use gold foil on ... The common reflectors are aluminum, silver, copper, and gold. Below, the plot of reflectance vs. wavelength shows that all four metals are good IR-reflectors since the reflectance is close to 100% for wavelengths greater than 700 nm (λ ≥ 700 nm). So why use gold? It’s most likely the same reason why they use gold extensively in circuit boards.
