Hafnium has a strong ability to capture the neutron, making it an excellent material for control rods in nuclear reactors. The nuclear industry roughly consumes half of the Hf produced every year. Hafnium is also used as an additive to alloys. Recently, scientists at Intel and IBM found hafnium-based compounds can be applied in gate insulators to make the processors smaller. Hafnium wires and other Hf parts are also used in plasma cutting because of their ability to shed electrons into the air. Cut hafnium wire could be inserted into copper parts to make a cutting tip for the plasma cutter.
