BTi-5 powder (in accordance with AWS A5.8) is a titanium based active brazing alloy powder. It is mainly used for high temperature vacuum / controlled atmosphere brazing. BTi-5 is a low temperature, highly active titanium based brazing powder specially designed for vacuum brazing of titanium alloys, ceramics, graphite and diamond. It is a key joining material in aerospace, electronics and special ceramic industries.

Key Physical Properties
Solidus temperature: 845°C
Liquidus temperature: 863°C
Recommended brazing temperature:
- 880–900°C for titanium alloys
- Above 920°C for ceramics / graphite
The minimum brazing temperature using this active filler metal is 850°C. Higher temperature improves the wettability of the brazing alloy.
Density: ~6.68 g/cm³
Service environment: high vacuum (above 10⁻⁴ Torr) or protective atmosphere
Key Characteristics
Active brazing:
Contains Ti/Zr, enabling direct wetting on ceramics, graphite, C/C composites and diamond without pre metallization.
Low temperature:
Melting point < 900°C, below the β transus temperature of titanium alloys, avoiding overburning of base materials.
High strength:
Joint strength is close to that of titanium alloy base metal, with excellent hermeticity.
Corrosion resistance:
Similar to that of titanium alloys.
Typical Applications
Aerospace: titanium alloy honeycombs, heat exchangers, blades, sealing components
Military/special industries: ceramic to metal, graphite to metal, diamond to metal joining
Electronics / vacuum: vacuum devices, Kovar alloy sealing, electronic vacuum brazing
New energy: fuel cells, high temperature sealing components
3D printing post processing: support removal for metal / ceramic parts, dissimilar material joining
