Copper absorbed tungsten

Some of the early reentry vehicles utilized metallic heat sinks of copper [7440-50-8] or beryllium [7440-41-7] to absorb reentry heat. Other metallic materials that have been evaluated for nosetip appHcations include tungsten [7440-33-7] and molybdenum [7439-98-7]. The melt layers of these materials are beHeved to be very thin because of the high rate at which volatile oxide species are formed.
