Havar is composed of 41-44% Cobalt, 19-21% Chromium, 12-14% Nickel, 2.3-3.3% of Tungsten, 2-2.8% Molybdenum, 1.35-1.8% Manganese, .17-.23% Carbon, .02-.08% Beryllium. It is known for its retained strength in high temperatures, anti-corrosive properties, and heat treatability. The medical industry also prefers Havar due to it being biocompatible and non-magnetic.
Characteristics of Havar:
- Very high mechanical strength
- High fatigue resistance
Havar Etching Applications:
- Medical implants
- Target foils
- Pressure sensing diaphragms
- Lends well to heat treating, welding, soldering, and brazing.
- Havar will maintain 75% of its strength up to 950 °F, with a melting point of 2696 °F.
