CarTech Nickel 205 alloy is a wrought nickel alloy having controlled additions of small amounts of magnesium and titanium. It has been used in various electronic components such as vacuum tube components, pins, terminals, support wires, lead wires, shields, tubes, etc.

CarTech Nickel 205 alloy exhibits an excellent combination of mechanical, electrical and corrosion-resistant properties. It exhibits good oxidation resistance. It is ferromagnetic below 680 °F (360 °C). The alloy meets the requirements of ASTM Specification F-9.

Low carbon CarTech Nickel 205 alloy (0.02% max. C), designated CarTech Nickel 206 alloy, is also available. This material has been used in applications requiring minimum evolution of gas in components (support rods and wire), where high temperature assembly (glass sealing) is required.
