Nickel Alloy 200
Principal Design Features: Commercially pure (99%) wrought nickel, basically unalloyed but containing minor amounts of other elements usually totaling less than 1%.
Applications: Electronic parts, resistance to corrosion applications such as handling alkaline solutions and foods.
Machinability: Commercially pure nickel is soft and “gummy” to machine. However, it can be machined with standard tooling. High-speed-steel tools work better than carbide tooling and it is important to maintain a high positive rake angle on cutting tools.
Welding: All of the conventional welding and joining methods work with nickel. In particular the shielded metal-arc, gas tungsten-arc and gas metal-arc welding methods are recommended. Use nickel filler wire or electrodes.
Forming: Nickel is readily formed by all of the conventional means. It behaves in a similar fashion to plain carbon steel, except that more power is required to form nickel.
