Product Description

Kovar expansion alloy plate, sheet, strip, wire, rod, bar (ASTM F-15) with huge stock

 

 

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
