Abstract
The invention relates to an Ag alloy solder used to improve the sealing property of vacuum device, which can reduce the solder cost, wherein based on the AgCu alloy solder, it adds some Ni component, to improve the property of solder, and improve the humidify property and welding strength of mother base of solder, and replace the Pd group solder in multi-stage welding, and reduce the cost.
Description
Technical field
The present invention relates to silver-based alloy solder, particularly relate to yellow gold solder and the application in vacuum circuit breaker step soldering thereof.
Background technology
Vacuum electron device is to be connected to form by welding method by multiple material, complex structure, and the dimension precision requirement height, soldering is the method for widespread usage.Because the mother metal performance of soldering is different, in being tightly connected, need from high temperature to low temperature, to carry out multistage soldering usually.For big clearance part, adopt AgCu50 to carry out soldering both at home and abroad at present in a large number, brazing temperature reaches 900 ℃, and the time is longer.The long performance that also can influence device of holding time.And the AgCu50 solder is bad to stainless wetability, also need plate Ni and handle, and has increased processing step and cost.
Summary of the invention
After the AgCu alloy adds the Ni constituent element, can be used for the soldering of copper-copper, copper-stainless-steel, kovar alloy and metallized ceramic and metal, be widely used in the multistage soldering of vacuum circuit breaker parts and other air locking soldering.
The purpose of this invention is to provide Cu:40%～45%, Ni:1%～5%, Ag surplus, serial solder.This series solder is applicable to the soldering of copper-copper in the vacuum circuit breaker spare, copper-stainless-steel, kovar alloy and metallized ceramic and metal, and its calking, wetability, free-running property, joint brazing intensity, soldering vacuum-tightness all reach the specification requirement of vacuum circuit breaker spare.
The present invention be directed to and improve the Ag base solder alloy performance that the vacuum device sealed welding uses and reduce the solder cost and carry out, on AgCu solder alloy basis commonly used, add an amount of Ni constituent element, the performance of solder is effectively improved, thereby improve wettability and the weld strength of solder to the soldering mother metal, and substitute the use of Pd brazing filler metal in the multistage soldering, reduce cost.
By in Ag base solder, adding an amount of Ni, the fusion temperature of solder suitably improves, solder is improved to the wettability of soldering mother metal, especially stainless steel material, holding time shortens in brazing process, minimizing is enhanced productivity to the influence of device performance, reduces the generation cost of vacuum device.
