Indium metal as a solder can provide a convenient and effective, last resort, patching material for leaks which occur spontaneously in metallic low-temperature apparatus. Indium bonds well to many metals and, more importantly, remains ductile to 4 K. An indium patch therefore retains its integrity even where a leak has occurred due to the differential thermal expansions of construction materials.
