More Information
Summary:The invention relates to the high-temperature alloy brazing material field, in particular to NiMnCoNbFeSiB strip brazing material. The strip brazing material comprises the following chemical compositions by weight percent: 30-40% of Mn, 8-14% of Co, 1.5-3.0% of Nb, 0.1-1.5% of Fe, 0.5-2.0% of Si, 0.05-0.5% of B and the balance Ni. The physical dimension of the brazing material is as follows: the thickness is 0.05-1.5mm, the width is 5.0-50.0mm and the length is unlimited. The brazing material is prepared by the rolling method, and the brazing temperature of the brazing material is 1150-1250 DEG C. The existing high-temperature brazing material can not meet the operating requirements along with the continuous occurrence of new materials and the increased standard of causative environment, and the invention can solve the connection problem of high-temperature alloy which can be used in special environments and have important industrial application value.
