Silver flux-cored wire

 

Flux-cored wire, also known as tubular wire, can be easily designed for a variety of welding materials by adjusting the type and proportion of flux-cored additives. As a widely used new welding material, the product has the characteristics of uniform core powder, no broken powder, no splashes, beautiful weld, good forming, good operation, easy to operate and so on.

 

 

Silver based solder

 

The silver base filler metal is an alloy mainly of silver or copper. This kind of solder has excellent process properties, low melting point, good wettability and caulking performance, excellent strength, plasticity, electrical conductivity and corrosion resistance, and is widely used in hard brazing materials.

 

 

Copper base solder

 

The solder has good plasticity and high melting point, which can be completed by flame brazing and induction brazing. Due to the high zinc content and a small amount of silicon in the filler metal, it is necessary to avoid overheating during brazing to reduce the effect of zinc volatilization on the compactness of the brazing joint.

 

Aluminum core filler metal

 

Aluminum flux-cored wire is a kind of composite brazing material with aluminum silicon alloy outside and white fluoride brazing agent inside. The white brazing agent is non - hygroscopic, non - corrosive, no need to clean after welding.

 

 

Cu-al core filler metal

 

Cu-al core filler metal is a kind of composite brazing material with aluminum silicon alloy outside and white fluoride brazing agent inside. The white brazing agent is non - hygroscopic, non - corrosive, no need to clean after welding.

 

 

Brazing agent (powder)

 

In the process of brazing, the wettability of molten solder and base metal mainly depends on the action of brazing agent. The main functions of brazing agent can be divided into three parts: matrix, film removing agent and interface active agent.
