KFWELD exothermic welding powder can be used to restore metal compounds and a certain percentage of the reduction of substances, and made by a special process. All products through the China National Nonferrous Metals Research Institute test center monitoring, product quality comparable to the well-known manufacturers of products, supporting KFWELD mold and accessories, to meet all the copper, copper clad steel materials, steel grounding welding requirements. Each bag welding powder standard with a bag ignition powder and disc steel plate.

1.KFWELD welding powder is a non-dangerous goods, the use of sealed waterproof design, solder powder does not contain phosphorus, magnesium and other harmful materials on the human body to facilitate transport and storage.

2. Product performance and stability, low porosity, in strict accordance with the construction process, can ensure that the solder porosity <1%.

3. Welding different types, specifications of metal quality, such as welding, according to different materials to provide different formulations of the solder powder, and according to different ways to provide accurate component packaging, through the reaction temperature and speed control, adjust the solder element composition and Ratio, so as to achieve the best welding performance, in the full guarantee of the quality of welding under the premise of the degree of standardization, not only to minimize the damage to the metal base metal damage, but also greatly improve the service life of the mold.

4. Welding powder reaction is full, very little solder impurities, solder joint conductivity and corrosion resistance is extremely high.
