Defect-free bonding technology as vacuum brazing using amorphous foil as a bonding zygote
| Type | Normal brazing | Ultra brazing |
|---|---|---|
| Zygote | Ag, Cu | Ti, Ni, Zr |
| Type | Binder and powder foil | Foil |
| Form | Crystalloid | amorphous |
| Defect | No cracks or pores | No cracks |
| Pre-processing | Metallizing | No metallizing |
| Temperature of brazing | High temperature | Low temperature |
| Base material deformation | Deformation | little deformation |
| Bonding strength | Low bonding strength | High bonding strength |
| Compound Layer Formation | Formation | No Formation |
MFTECH Co., Ltd.'s ultra-brazing has the biggest strength of superior bonding strength.
• No pores(Ultra brazing)
The space where the binder came out
• Pore generation(Brazing)
• Pore generation(Normal brazing)
It can be seen that the aluminum of Al2O3 is diffused into titanium due to its high diffusion force.
