Applications in Hermetic Engineering
High-Temperature Seals
Ideal for brazed joints in vacuum or oxidizing environments due to nickel’s thermal resistance and mechanical strength.
Chemical Barrier Layers
Nickel serves as a diffusion barrier or plating layer to prevent corrosion and metal migration in harsh process media.
Electrical Connectors & Shields
Used in RF and high-frequency assemblies where conductivity and stability against environmental degradation are essential.
Aerospace & Energy Systems
Integrated into sensor packages, thermal plates, and EMI shielding in critical systems exposed to thermal cycling and vibration.
Nickel Brazing Alloys
Nickel-based filler materials are widely used for joining dissimilar metals in hermetic packages operating under extreme stress.
