The raw materials used for the construction of BART broaches are chosen among the best high-speed steels or sinter available on the market, which come exclusively from European foundries.
The choice of the right steel ensures that the broach works properly, guarantying greater productivity.
High-speed steels are divided by their chemical composition, based on tungsten, molybdenum and tungsten-molybdenum. They are also present in various percentages of carbon, vanadium and cobalt. The common characteristics are good hardness, wear resistance and toughness.
Sintered steels are produced by powder- metallurgy methods.
Segregation-free and homogeneous metal powders are processed in a diffusion process that taking place at high pressure and temperature.
