Titanium based brazing alloys

Strong Point

Tokyo Braze ORIGINAL

  • This is suitable for brazing of pure titanium and titanium alloy.
  • It is possible to braze pure titanium at lower temperature than βtransus temperature.
  • This brazing alloys has the same corrosion resistance as titanium because it is powder alloy which mainly consists of titanium and zirconium.

Test of corrosion resistance(720hours dipping)

This shows the same corrosion resistance as based metals.
  • We have 2types of Titanium based brazing alloys Paste and powder
  • It is used in vacuum or in the non-active gas atmosphere
  • The joint strength changes according to the shape of joint or the condition of brazing.

Example of application

  • Medical part
  • Parts for aircraft
  • Parts for semiconductor device
  • Parts for automobile for competition
  • Parts for cutting tool
  • Mug as consumer product
  • etc.
