Alloy MNMTs 68-4-2

At its core, the material is solder. It consists of 62 to 68% copper, 4-5% nickel and 1.5 to 2.5% manganese. The share of other impurities in total does not exceed 0.3%.

Special properties

Single-layer solder MNMC 68-4-2 stands out for its good spreadability over the surface to be soldered. It provides high strength soldered seam. However, it causes residual solder stresses in hard alloys, which can lead to the formation of cracks and breakage of soldered products during their operation.

temperatures 915-975 degrees. The soldering process itself is performed at 980-1010 degrees.

The solder plant produces its products specifically for the manufacture of carbide metal-cutting tools operated at high temperatures. The manufacture of cutting plates made of various types of alloys can be indicative. However, high-temperature material is also used in the production of strips, tapes, soldering of various engineering products, various structures, and so on.
