Flux cored solder wire

For Aluminum wire soldering K4-C601-3
Comply to aluminum wire

Solderable by iron to aluminum wire, used such as in the HDD of the actuator.

Solderable to aluminum

●Soldering test to aluminum

Solderable to aluminum
Put solder wire on aluminum board and heat by 270℃

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

Measure the time until the solder delamination occurs, stored in 40℃ of artificial seawater, after soldering the two aluminum plates

Good water washability

Apply water-soluble base material instead of rosin.The residue after soldering is possible to wash away easily with water.

Good water washability

●Ionic residue test

The flux residue is possible to clean with water
