| Applications |
CuBe2 (C17200) is used as forms for plastics, tools for
deep-drawing, injection moldings, molds for non-ferrous metal casting, safety tools
(non-sparking and non-magnetic), pistons for die casting,
non-magnetic,
high-tensile bars, bushings for deep drilling rods in offshore and
onshore sectors, and components for precision measuring instruments. It
is also used in the off shore oil and gas, crosswire welding, wheel rim
welding, rail welding and radiator welding industries.
