Product Introduction
singway 25A solder bars are made from high purity Yunnan tin metal and are treated by vacuum deoxidation and uniform casting process, with a range of outstanding features for a variety of welding applications:
The first high purity tin gold raw material: We choose high purity Yunnan tin gold raw material to ensure the quality of the raw material of the solder bar, reduce the content of oxidation and impurities, so as to provide high quality welding performance.
The second vacuum deoxidation treatment: the solder strip is subjected to vacuum deoxidation treatment, which effectively reduces the oxygen content, reduces the oxidation reaction, and ensures the stable quality of the solder joint during welding.
Third, uniform casting process: The use of uniform casting process to ensure the uniformity and consistency of the solder strip, uniform temperature distribution during the welding process, and improve the quality and stability of the solder joint.
Fourth, effective control of impurities: by strictly controlling the content of metal and non-metal impurities, to ensure the purity of the solder bar, improve the reliability of welding.
Fifth wide application: suitable for a variety of welding applications, including electronics, electrical, metal processing and other fields, to provide a wide range of welding solutions.
Sixth reliable quality: After strict quality control and monitoring, our 25A solder bars ensure reliable quality and provide a highly stable material for welding tasks.
