Main highlights- Wide Uses: Suitable for welding of various metals such as stainless steel, galvanized sheet, nickel, copper, iron, etc. Widely used in the production of various stainless steel products, advertising characters, battery electrodes, clocks, precision parts, PCB boards, etc. (not applicable to aluminum alloy materials)
- Protective Layer: During the welding process, the liquid solder flux can form a protective layer to prevent the metal surface from oxidizing again. Soldering flux liquid provides a longer operating time and is suitable for complex or delicate welding operations
- Package Includes: 80ml liquid flux, 50g soldering wire, 10 alcohol pads, liquid flux has stable performance, durable, colorless and odorless, long service life, and strong welding
- Non-corrosive: The formula has a neutral pH value and will not corrode after the welding process. It is non-conductive and has good insulation under dry conditions. It is non-corrosive to metal surfaces such as circuit boards
- Anti-oxidation: It has an antioxidant effect in welding, desoldering, rework and reflow electronic processes. The liquid flux can reduce the surface tension of the solder, making it easier to flow and spread, which helps to form smooth and uniform solder joints and reduce cold solder joints and solder balls
