What This Process Solves
Solid-state atomic diffusion bonding without filler metal, minimal deformation and excellent hermeticity.
Good uniformity
Fast heating
High pressure accuracy
High safety
Fast cooling
Suitable Materials & Applications
Dissimilar metal bonding
- Titanium-stainless steel
- Titanium-aluminum
- Copper-aluminum
- Copper-steel
Ceramic-metal joining
- Alumina, zirconia, and silicon carbide to Kovar, titanium, copper, nickel, and stainless steel
Functional composites and cemented-carbide structures
- Diamond-copper and diamond-aluminum thermal composites
Evaluation Boundary
Final feasibility depends on material composition, geometry, atmosphere window, thermal profile, target performance, and downstream testing requirements. For immature formulas or complex dissimilar joining, small-sample validation is recommended first.
