KM50 - Most extensively used alloy for Cutting Tools.

KM50 NWC, KM49, KM49Cu
- These alloys are used for brazed Tools which are further subjected to PVD Coating.

KM40 Ni
- Popular alloy for Diamond Cutter.

KM43
- This alloy is very much suitable for joining of carbide in Work Rest Blades.

KMCM27
- This alloy is used in Mining Tools like Buttons Bits, Coalagur Drills, Coal Picks etc. This alloy is also used in joints of carbide for Deburring Tools.

KM25 N, KM20 N - High temperature brazing alloys specially used for Deburring Tools.

KMCMF - This alloy is equivalent to "F" Bronze alloy and used in manufacturing of Drills Rods.

KMCuN - This alloy is popular recognized as Copper Brazing Strip and used in joining of Carbide for Drill Rods.

KMNB10 - Very much suitable for Masonary Drills.
-----------------------------------------------
Brazing Flux
Kranti is making fluxes to suit various alloys and application is Powder & Paste from.
KFS1 - Powder flux suitable for alloy in the melting range 550o C to 850o C i.e. for KM43, KM35, KM30

KFS2 - Powder flux for KM50, KM40 N alloy.

KFSP2 - Paste Flux for KM 50 alloy.

KFC - Brazing flux in powder form suitable for KMCuN alloy which is used in joining of carbide in Drills Rods.

KFSP3 - Paste flux suitable for joining of stainless steel while using alloy KM56N, KM56ZS.
 
Copper Brazing Alloys
All these alloys are used for joining of Copper to copper without any external Flux. But for joining of Copper to Copper alloy flux is necessary.
