Premium Vacuum Brazing Paste for PCD/PCBN Tools, 27.25%Cu, 12.5%In, 1.25%Ti, Bal.Ag
We provide many advanced vacuum brazing pastes from Germany and USA. These pastes could be brazed in different brazing temperature.
When brazing with active solder, the protection of active elements is a very important aspect. These elements are very easy to oxidize, and can no longer react with ceramics after being oxidized.
Therefore, the vacuum degree of the furnace is required to be very high, less than 10e-2

Different from other high frequency welding,our vaccum brazing way can save much cost.The vaccum welding flux is used for fitting process to make the PCD, CBN, CVD and other ultra hard inserts in to alloy tools in the vacuum brazing machines. It's only 0.001g of each time can make the very strong strength.These flux could be brazed in the different welding temperature with effectively work.
CHN-TOP offer full specification of brazing flux for PCD PCBN diamond tools
