Cadmium Spooled Wire

Cadmium Spooled Wire is a conductive metal filament offered in Goodfellow's extensive range of wires and rods. With 113 diameter variations, this malleable and ductile wire has numerous applications including as an electrode material, in nuclear reactors to control neutron flux, and in specialist solders. Its low melting point and resistance to corrosion by alkaline solutions make cadmium an important engineering material for industrial components operating in demanding conditions.
