4 No oxidation or any residual Cutting edges free of burrs or burnings Remove any «white layer» Holes or threads should be present for fixturing Not magnetized

5 Roughness as low as possible Never polish with rubber wheels No diamond paste below 3 microns Sisal wheels with white or light blue accepted

 Brazing alloys not containing Cd and Zn  Brazing alloys resist at high T (>600°C)  Surface protection with slight oil layer easy to remove  Moulds must be prepared cleaned with solvents 6
