Rock chisel
As an application from the tool-making industry for stone work, these photos show rock chisels.
The brazing can be carried by induction or in the furnace under an inert gas atmosphere.
Brazing can be carried out using either BrazeTec 21/68 brazing alloys for hard metals (working temperature ca. 1020°C) or BrazeTec 21/80 (working temperature ca. 990°C).
A flux is not required when using an inert gas.
