Problems solved by technology

However, the brazing strength of this silicon bronze alloy solder is not high, the corrosion resistance is poor, and the work hardening is fast, so repeated annealing and pickling are required in wire drawing production.
Long production cycle, high energy consumption, large loss and serious pollution have hindered the production and application of this solder alloy

Abstract

The invention discloses a brazing titanium-copper alloy with high strength and corrosion resistance. The brazing titanium-copper alloy comprises the following ingredients in percentage by mass: 2.8-3.5% of Si, 1.0-1.2% of Mn, 0.2-0.4% of Ti, 0.05-0.08% of Ce and the rest amount of Cu. The brazing titanium-copper alloy disclosed by the invention has the advantages of high brazing strength, excellent corrosion resistance and good machining performance. As a small amount of Ti and Ce is added in the Cu-Si alloy, the brazing alloy provided by the invention has an obviously-fined grain size for casting line blanks, and the grain size is about one third of that of the S211 alloy.

Description

technical field [0001] The invention relates to the field of brazing alloy materials, more specifically, relates to a high-strength corrosion-resistant brazing titanium-copper alloy. Background technique [0002] At present, S211 (Cu+2.7~3.5%Si+1.0~1.5%Mn) silicon bronze alloy solder is mostly used for laser brazing of automobile body panels, MIG arc brazing and other welding wires, and the annual consumption at home and abroad exceeds 5,000 tons. However, the brazing strength of this silicon bronze alloy solder is not high, the corrosion resistance is poor, and the work hardening is fast, so repeated annealing and pickling are required in wire drawing production. The production cycle is long, the energy consumption is high, the loss is large, and the pollution is serious, so the production and application of the solder alloy have been hindered. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies i...
