Description
Alloy МНМц68−4-2 is used: for the manufacture of tapes, strips and bars used for welding of machinery; for brazing of sintered hard alloys in the manufacture of carbide cutting tools.
Note
The alloy system Copper-Zinc-Nickel-Manganese.
Solder МНМц68−4-2 — single layer, good flow on the brazed surfaces, in comparison with solder ЛМцЖ57−1,5−0,75 provides higher strength of the solder joint, but causes a higher level of residual stress in soldering the solid alloy, which may increase the likelihood of cracking during production and damage when operating the tool. Recommended for brazing of cutting tools operating under severe conditions at elevated temperatures. The application is only useful if the strength of the solder joint when using solder ЛМцЖ57−1,5−0,75 insufficient.
