Solder bar・Solder wire
For aluminum soldering type K4S
Prevent galvanic corrosion
Additive elements achieve high soldering reliability and prevent the galvanic corrosion that occurs between the aluminum material and solder.
High soldering reliability
●Electrolytic corrosion test
High corrosion life and soldering reliability
Measure the time until the solder delamination occurs, stored in 40℃ of artificial seawater, after soldering the two aluminum plates.
High working stability
Suppress the generating of dross, which particularly problematic in the terminal treatment of aluminum wier.Reduce the number of the replacement of solder bath,to ensure the work efficiency.
Reduce of dross
●Soldering mass production test
Long time stable soldering
Bath temp:400℃
Applicable to aluminum coil wire
Available to the terminal treatment with dipping of aluminum wire that rapidly spread to such as an air conditioner compressor motor.
Applicable tothe terminal
