Loctite Wire Solder, 227 → 310°C Melting Point

The Loctite ALU flux cored solder wires 97CU3 alloys have been specially formulated for use in aluminium soldering applications. Its contain a unique combination of highly developed flux allowing wetting of many of the more difficult aluminium alloys with a solder alloy having better penetration and greatly improved resistance to electrolytic corrosion.
