Abstract

The invention relates to a low-temperature brazing material for titanium alloy, which relates to a low-temperature brazing material used for metal welding, especially for welding various and titanium alloy parts. It is characterized in that the brazing material is powdered silver-based brazing material, and its weight percentage is composed of: Sn: 20%-40%, Cu: 10%-30%, Ni: 0.5%-5%, and the rest are Ag and unavoidable impurities. After the titanium alloy parts using the brazing filler metal of the present invention are vacuum brazed, the bonding strength of the parts can reach more than 50 MPa. Since the precise, light and thin titanium alloy parts are brazed at 600°C, deformation and failure of the parts are avoided, and the weld seam has high strength and corrosion resistance.

Description

A kind of low-temperature brazing filler metal for titanium alloy, preparation and application method of solder technical field A kind of low-temperature brazing filler metal for titanium alloy and using method thereof, relate to a kind of for metal welding, be especially used in various A low-temperature brazing material for welding titanium alloy parts. Background technique The brazing temperature of conventional titanium alloy brazing material is higher at present, generally more than 800 ℃, and some electronics, chemical industry etc. In the application field, it is often necessary to weld some precise and thin titanium alloy parts, and high temperature brazing will easily cause these parts to deform and fail. Therefore, the requirements for use cannot be met. Contents of the invention Summary of the invention The purpose of the present invention is exactly in order to overcome the deficiency that above-mentioned prior art exists, provide a kind of can treat at...
