End-mill
Another example from the tool-making industry (metal processing) is shown by these hard metal end-mills where hard metal has been brazed to steel by induction brazing or flame brazing.
BrazeTec 49/Cu brazing alloy is recommended (working temperature 690°C).
This incorporates a copper interlayer which can compensate for stress caused by the different thermal coefficients of expansion.
BrazeTec spezial h is recommended for the flux.
