Kovar* (ASTM F-15)
Character of Kovar expansion alloy
Kovar alloy is magnetic at all temperatures below the Curie point. Magnetic properties will depend upon heat treatment; the lower the hardness, the higher the permeability values and lower hysteresis loss.
Density: 8.36g/cm3
Curie Temp: 435°C(815°F)
Introduction of Kovar expansion alloy
Kovar is a Ni-Fe alloy with 29% Nickel, 17% Cobalt and the remaining balance is Iron. The expansion characteristics of Kovar match both borosilicate (or Pyrex) glasses and alumina ceramics, making it one of the most popular of the controlled expansion alloys for hermetic sealing applications.
Chemical composition of Kovar alloy
C≤0.020, Ni≤29.0, Si≤0.20, Mn≤0.30, Co≤17.0, Fe=remainder
Delivery
Huge stock of strip, bar and wire in stock. Fast delivery with 5 days for customized size. Delivery of other products please confirm with A-one Alloy.
Forms available at A-one Alloy
