Nickel HAVAR

Applications

Havar is commonly found in springs, diaphragms and target foils for nuclear physics.

Formability

Large radii must be allowed for in tool design of Havar.

Principle Design Features

Havar is a heat treatable, cobalt base alloy offering high strength and corrosion resistance. The alloy will retain up to 75% of its mechanical properties up to 950 F.

Weldability

Havar can be successfully joined by most common welding or soldering methods.
