The material properties of silver-copper-titanium activated brazing metal include the following aspects:
1. Excellent wettability: AgCuTi alloy has excellent wettability, which makes it excellent in the brazing connection between ceramics and ceramics, metals and ceramics and carbon materials, and the quality of wettability directly affects the quality and reliability of brazing joints. Experiments have shown that AgCuTi exhibits excellent wettability and spreadability on different substrates such as Cu, TA1 and TC4.
2. Good corrosion resistance: experiments have proved that titanium can improve the comprehensive mechanical properties of silver-copper alloys, and the alloy with titanium has good resistance to seawater corrosion, and the material can be popularized as an instrument node material for navigation vessels.
3. High wear resistance: the silver-copper-titanium alloy metal parts are evenly distributed, and the presence of Ti can refine the grains of the silver-copper alloy, increase the grain boundaries, and play a role in strengthening the alloy, so that the hardness and strength of the alloy are improved, thereby improving the wear resistance of the material.
4. Good electrical and thermal conductivity: AgCuTi brazing metal can quickly transfer heat during the brazing process, and can achieve good current conduction, which makes silver-copper-titanium brazing metal widely used in the assembly and manufacture of electronic devices.
5. High adaptability: Silver-copper-titanium solder is suitable for the connection of a variety of materials and composite ceramics with active metals, including ceramic-ceramic, ceramic-metal and metal-metal combinations.
6. Good processability: AgCuTi solder can be prepared into strip by rolling, quenching and other methods, and can also be manufactured into alloy powder or solder paste, which is convenient for different types of welding applications.
