"Friction welding of Chromium copper + Pure Titanium type 2" January 28, 2021

For the first time, we have established a good friction welding technology for Chromium copper (C18200) and Pure titanium type 2.

Pure copper (C1020) and Pure titanium type 2 have been applied with good friction welding technology so far, but Chromium copper has stronger strength than Pure copper, so it could not be bonded under similar conditions.

As a result of trial and error, it was confirmed that the Chromium copper side bends without breaking the joint in the bending test centered on the joint as shown in the photograph.
