Soldering possible with aluminum The "EVASOL EAN series" uses a special fluorine compound as an activator. Even aluminum parts, which are difficult to solder, can be soldered with strong reactivity. New Applications It enables soldering to aluminum wires, which was previously impossible. It allows for the introduction of aluminum wires in a wide range of applications. No-clean compatibility It suppresses corrosion and ensures reliability after joining. Like regular rosin-core solder, cleaning of flux residue is not necessary. 【Features】 ■ Soldering possible with aluminum ■ Enables the introduction of aluminum wires in a wide range of applications ■ No-clean compatibility due to suppressed corrosion *For more details, please refer to the PDF document or feel free to contact us.

Soldering to aluminum wire is possible. Due to the strong oxide film on the aluminum surface, it was difficult to remove with flux, but this product can remove the oxide film, making soldering possible. No cleaning process is required. Although it is a highly active flux, it only activates during soldering (at high temperatures), so no cleaning process is needed after soldering. No prior removal of the urethane coating is necessary. For some aluminum coil wires, the heat from the solder and the flux can remove the urethane coating, allowing soldering to aluminum wire with the urethane coating removed. Therefore, there is no need to separate the coating removal and soldering processes, which increases productivity. 【Features】 ■ Removes the oxide film on the aluminum surface ■ No cleaning process required ■ No prior removal of the urethane coating necessary

Support for aluminum wire It can be used for terminal processing of aluminum wire, which is rapidly spreading to air conditioner compressors and other applications, through a dip tank. Prevention of electrolytic corrosion Electrolytic corrosion that occurs between aluminum materials and solder materials is prevented by added elements, achieving high joint reliability. High work stability It suppresses the occurrence of dross, which is particularly problematic in terminal processing of aluminum wire. This reduces the number of times the solder tank needs to be replaced, ensuring work efficiency. 【Features】 ■ Reduction of dross caused by aluminum ■ Support for terminal processing of aluminum wire ■ High joint reliability *For more details, please refer to the PDF document or feel free to contact us.

Compatible with aluminum wire The "EVASOL C601 series" can be used for soldering aluminum wire, such as that used in HDD actuators, with a soldering iron. Prevention of electrolytic corrosion Electrolytic corrosion that occurs between aluminum materials and solder is prevented by added elements, achieving high joint reliability. Good washability Instead of rosin, a water-soluble base material is used. Residues after soldering can be easily washed away with water. 【Features】 ■ Solderable to aluminum ■ High joint reliability ■ Good washability *For more details, please refer to the PDF document or feel free to contact us.
