Aerospace Applications We Support

  • Engine Components & High Temperature ApplicationsGold-nickel and other high-purity filler metals for assemblies exposed to sustained temps approaching or exceeding ~900°F, such as turbine speed/torque sensors and hot-zone hardware. 

  • Sensors & Instrumentation (Pitot Probes, Thermal, Pressure)Silver-based alloys with nickel additions promote wetting on stainless steels, resist interface corrosion, and produce smooth, accurate, airflow-friendly joints. 

  • Fluid & Thermal Management SystemsReliable joints that hold pressure and resist corrosion across altitude-driven thermal cycling; material choices tuned to base metals and service media. 

  • Structural & Support AssembliesDurable, long-service brazed connections that help maintain equipment integrity across the aircraft lifecycle.

Quality, Traceability & Joint Integrity

Meeting aerospace requirements goes beyond alloy chemistry. It’s about process discipline, documentation, and cleanliness. Our AS9100 framework, layered on ISO quality foundations, drives defined procedures, data-driven corrective action, and product quality verification. Combined with vertical integration and high-purity melt control, this helps prevent impurity-driven leak paths and supports long service life in critical assemblies. 

Engineering Partnership & COE Support

From new product introduction to ongoing production improvements, our brazing engineers collaborate with your design, manufacturing, and quality teams. Use our Center of Excellence for prototyping, alloy testing, joint design reviews, and process optimization that can boost productivity and reduce rework. We invite you to bring your toughest aerospace brazing challenge, let’s solve it together. 

Vertical Integration 

With our ability to process material on-site, our vertical integration supports improved price, delivery speed, full material traceability, and consistent chemistry.
