Abstract

The invention discloses a formulation of high-manganese cupronickel brazing filler metal and a production process of the high-manganese cupronickel brazing filler metal. According to the formulation of the high-manganese cupronickel brazing filler metal, the high-manganese cupronickel brazing filler metal is prepared from the components in percentage: 8.5-10.5% of Ni, 36.5-38.5% of Mn and the balance of Cu. The production process of the high-manganese cupronickel brazing filler metal comprises the steps of batching, vacuum melting, forging, rolling, drawing and annealing, scaling and finishedproduct drawing, finished product annealing, inspection and packaging and storage. The requirements of electronic valve welding can be met, and the fluidity and the wettability during welding and thecorrosion resistance and the welding strength after welding can be met; and the electronic valve cost is greatly reduced. The production process of the high-manganese cupronickel brazing filler metalhas simple and convenient operation steps, perfect steps and high quality of produced welding wires.

Description

technical field [0001] The invention relates to the field of brazing filler metal, in particular to a formula of high manganese nickel-nickel brazing filler metal and a production process thereof. Background technique [0002] The welding of electronic tubes generally uses silver-copper solder, which is composed of 72% Ag and 28% Cu. This solder is very expensive, costing more than 3,000 yuan per kilogram, and the price is extremely high. The welding cost of electronic tubes remains high. [0003] For this reason, a formula and its production process of high manganese white copper solder are designed to solve the above problems. Contents of the invention [0004] In order to overcome the above disadvantages, the present invention provides a formula of high manganese white copper solder and its production process. [0005] A kind of formula of high manganese nickel-nickel brazing filler metal, comprising components and percentages are: [0006] Ni 8.5-10.5%; [0007] Mn3...
