Use brazing alloy thin-walled parts Ti-Cu-Ni-Zr

The present invention relates to a method of using Ti-Cu-Ni-Zr alloy brazing thin-walled parts, by using a solder Ti-Cu-Ni-Zr, and controls the brazing temperature, holding time, to achieve the control connection organizational purposes and shear strength, connection successfully titanium thin-walled parts, and to obtain a high strength, high permeability rate of the brazing joint, the shear strength of the joint reaches 557MPa ~ 597MPa, brazing penetration rate of 95%. The present invention uses a Ti-Cu-Ni-Zr alloy brazing thin-walled parts to a successful connection, the connection for aerospace engines, thin-wall parts titanium alloy to achieve high strength, high quality connection, to solve the aviation cold end aerospace engine parts by weight of high prevalence, corrosion resistance is poor.
