ASTM F15 Kovar Alloy

Specialized stamping for Fe-Ni-Co alloy with matched CTE for glass-to-metal sealing applications

Technical Overview

Kovar Stamping: Precision Forming for Critical Applications

Kovar (ASTM F15 / UNS K94610) is a nickel-iron-cobalt alloy renowned for its matched thermal expansion coefficient with borosilicate glass and ceramics. Our specialized stamping processes leverage Kovar’s unique material properties to produce high-integrity components for hermetic sealing, aerospace, medical, and electronic applications.

Unlike standard metal stamping, Kovar stamping requires specialized tooling, precise process control, and material handling expertise to maintain the alloy’s critical thermal properties while achieving tight dimensional tolerances.

Key Kovar Stamping Advantages

  • Maintains critical thermal expansion properties post-stamping
  • Enables complex geometries with minimal material stress
  • Produces consistent, repeatable parts at scale

Thermal Stability

Specialized stamping parameters preserve Kovar’s thermal expansion characteristics critical for glass sealing.

Tight Tolerance Control

Achieve dimensional tolerances down to ±0.01mm on critical features, essential for hermetic sealing applications.

Material Efficiency

Optimized nesting and stamping processes minimize material waste for cost-effective production.

Complex Forming

Deep drawing, progressive stamping, and multi-stage forming for intricate Kovar component geometries.
