C103
It is a low-strength and high-plasticity alloy. Compared with other refractory metal alloys, it has higher specific strength (strength/density), excellent plasticity, processing and welding properties. At the same time, it also has a small thermal neutron absorption cross section, resistance to liquid metal corrosion and excellent superconductivity. It is regarded as one of the most promising high-temperature materials.
