According to the manufacturer of brazing strip, brazing strip is an important material for brazing process. Brazing is a welding method, which uses a brazing material with a melting point lower than that of the base metal to be heated to melt, but the heating temperature is lower than the melting point of the base metal, and then the melted brazing material is used to fill the weld, wet the base metal and diffuse with the base metal to form a whole. According to the different melting point of the solder, brazing can be divided into brazing and soldering. When brazing, the oxide film and oil on the contact surface of the base metal should be removed first, so as to facilitate the capillary to play a role after the melting of the brazing material and increase the wettability and capillary fluidity of the brazing material. The brazing process usually includes assembling the cleaned workpieces together in a lap joint type, placing the brazing filler metal near or between the joint gaps, then heating the workpiece and the brazing filler metal to a temperature slightly higher than the melting point of the brazing filler metal to melt the brazing filler metal (the workpiece does not melt), and being sucked into and filled between the solid workpiece gaps by capillary action, and the liquid brazing filler metal and the workpiece metal diffuse and dissolve each other to form the brazing joint after condensation. Brazing bar manufacturers say that brazing has many advantages, such as being suitable for applications that require high strength and high temperature resistance, such as aviation, shipbuilding, vehicle manufacturing, and chemical industries. In these areas, brazing is widely used to join a variety of metal materials, such as aluminum alloy, titanium alloy

According to the manufacturer of brazing strip, brazing strip is a special welding material, which is mainly used to connect different types of metals and plays a vital role in the welding process. Its function is reflected in many aspects, and the main function of the brazing rod will be discussed in detail below. The brazing strip enables the connection of different types of metals. In metal processing and manufacturing processes, it is often necessary to connect different types of metals, such as steel and copper, copper and aluminum, etc. Due to the differences in physical and chemical properties of these metals, it is difficult to effectively connect them by traditional welding methods. The emergence of the brazing bar, just to solve this problem. It uses a metal with a lower melting point than the material to be welded as a brazing filler metal, melts during heating, and fills the brazing filler metal into the gap of the joint contact surface through capillary action, so as to realize a reliable connection between different types of metals. Braze bar manufacturers state that the braze bar excels in joining sheet metal parts. In the production process of jewelry, tin ornaments, etc., it is necessary to finely connect the thin plate parts without damaging the surface of the parts. The brazing rod has a low melting point and does not cause thermal damage to the sheet parts during heating, so it is very suitable for this type of fine welding work. Braze bars are also commonly used to repair and reinforce parts. When the metal parts come out

Brazing rod is the key material used in the brazing process. It has a wide variety of characteristics and is suitable for different brazing needs. Brazing strip manufacturers share several common types of brazing strips and their characteristics: Silver brazing strips: Silver brazing strips occupy an important position in the field of brazing for their high strength, high electrical conductivity, high thermal conductivity and good corrosion resistance. Braze bar manufacturers say it is mainly used for welding steel, alloy steel, copper and its alloys, especially in the need for high strength and excellent electrical conductivity of the occasion. However, the price of silver brazing strip is relatively high, and the cost of use is also high, so it may be limited in some cost-sensitive applications. Copper flux: copper flux is widely used in brazing flux, it can be divided into hard copper flux and soft copper flux two. The brazing seam of hard copper flux has high hardness and is suitable for brazing of metal structures, while the brazing seam of soft copper flux is soft and its application range is more extensive. Copper flux is suitable for steel, copper and its alloys melting point lower than a variety of hard flux of metal materials, such as steel brazing, mechanical processing equipment brazing, food processing equipment brazing. Aluminum brazing flux: The manufacturer of the brazing strip stated that the aluminum brazing flux is a special flux, especially suitable for brazing of aluminum and its alloys. Its advantages are in
