Product Description

72% Silver Brazing Alloy DIN EN 1044 AG 401 BAg72Cu Soldering Wire

Silver copper solder is a solder with silver solid solution, copper solid solution or Ag+Cu phase as the main body. It has excellent process performance, suitable melting point, good wettability and joint filling performance, high mechanical strength, good plasticity and excellent conductivity of brazing joints. It can be used to braze ferrous and non-ferrous metals, such as copper alloys and titanium alloys.Stainless steel, carbon steel, hard alloy and other materials. It is widely used in refrigeration, lighting, mechanical appliances, instrumentation, cutting tools, aerospace and other industries. Generally, in addition to brazing in a vacuum furnace or in a shielding gas, silver flux is required to obtain an excellent brazing joint.
