Product Description
Solder SelectionThe performance of the brazing material greatly affects the performance of the brazing process and determines the performance of the brazing joint. Therefore, in the wide variety of brazing materials, its choice should be based on the requirements of the joint use, the relationship between the brazing material and the base material. Matching, brazing and heating process, and economic costs are determined by comprehensive consideration
Because the composition of the brazing filler metal and the base metal are often very different, they are prone to electrochemical corrosion. When the joint has corrosion resistance requirements, the brazing material selected should ensure the corrosion resistance of the brazed joint. For example, for aluminum solder joints, zinc-based solders with better corrosion resistance should be usedALUMINUM SOLDERProduct code | Al | Si | Zn | Mg | Cu | Co | Solid-liquid phase(ºC) | Brazing temperature(ºC) | Common application |

Solder PasteSolder paste is a homogeneous mixture, which is a paste with a certain viscosity and good thixotropy. It is a mixture of alloy solder powder, paste flux and some additives. It is a homogeneous and stable mixture. At normal temperature, the solder paste can initially stick the electronic components to a predetermined position. When the solder paste is heated to a certain temperature, with the evaporation of the solvent and some additives, and the melting of the alloy powder, the solder paste reflows to make the soldered components and The pads are interconnected together and cooled to form a permanently connected solder joint.Solder PowderWelding powder is also called flux. It is mainly a powdery material that improves the weldability during the high-temperature welding of metals and alloys. By dissolving the welding powder, the fluidity of the material surface is improved, and at the same time, the melting point of the weld metal can be reduced. Powders contain different ingredients in them, and they also play different roles. The flux used for welding different materials is also different.
Commonly used types of solder powder are nickel-based solder powder, silver-based solder powder, aluminum-based solder powder, copper-based solder powder and so on.Solder StripThe solder strip generally has the characteristics of low melting point, good wettability and caulking performance, and high strength of the instrument. Excellent conductivity and corrosion resistance, can be used to braze parts of black and non-ferrous metals, such as stainless steel, carbon steel, cemented carbide, copper and copper alloy, diamond and other materialsSolder WireThe Solder wire is used as a filler metal or as a wire welding material for electrical conduction. In gas welding and tungsten gas shielded arc welding, the welding wire is used as a filler metal; in submerged arc welding, electroslag welding and other molten electrode gas shielded arc welding, the welding wire is both a filler metal and the welding wire is also a conductive electrode. The surface of the welding wire is not coated with anti-oxidation fluxHow to order the solder you need? 1.Please tell us your information such as brazing temperature,brazing material,or the component of your solder, etc.
