LEADED SOLDER WIRE
Sn60/Pb40
MG Chemicals Sn60/Pb40 electronics-grade solder wire is formulated from a blend of 60% tin and 40% lead. Made from non-
recycled metal, our flux core manufacturing process eliminates flux voids and irregular wires. This wire melts at a slightly higher
temperature range than the Sn63/Pb37 solder, resulting in robust and reliable joints that are highly resistant to whisker formation.
This alloy puts down a slightly thicker coating of solder. It is often preferred for lead tinning and other solder coating applications.
These solder wires meet J-STD-004 and J-STD-006 specifications. This type of solder wire is available in a wide variety of sizes,
diameters and gauges, allowing you to select the perfect fit for your specific needs.
Sn60/Pb40 RA Solder Wire
MG Chemicals Sn60/Pb40 Leaded Solder uses a classical tin-
to-lead alloy ratio, complemented with an RA flux core, which
results in robust and reliable joints that are highly resistant to
whisker formation. The RA Flux residue is non-corrosive and
non-conductive, and can be left on the board or cleaned with
one of MG’s flux removers. (see page 14)
Sn60/Pb40 NC Solder Wire
MG Chemicals No Clean formula uses a synthetically refined,
splatter-proof, resin flux core. It leaves a small amount of post-
soldering residue that is non-conductive and non-corrosive, and
won’t cause electrical shorts.
The No Clean name refers to the fact that the board will
not be adversely affected if it isn’t cleaned. It does not
mean there will be no residue.

Sn63/Pb37
MG Chemicals Sn63/Pb3 electronics grade solder wire is formulated from a blend of 63% tin and 37% lead. Made from non-
recycled metal, it uses the eutectic tin-to-lead alloy ratio. Our flux core manufacturing process eliminates flux voids and
irregular
wire.
Being eutectic, it has no plastic range. This type is one of the easiest solders to work with because it offers a low
melting temperature with a sharp melting/solidification point, which results in robust and reliable joints that are highly resistant
to whisker formation. In most situations it flows better than the Sn60/Pb40, and is the preferred alloy for rework, component
attachment and touch-up soldering for through-hole and surface mount applications. It meets or exceeds J-STD-004 and
J-STD-006 specifications. This wire is available in a wide variety of sizes, diameters and gauges, allowing you to select a perfect fit
for your specific needs.
Sn63/Pb37 NC Solder Wire
This wire features a no-clean, synthetically refined, splatter-
proof resin flux core. It leaves a small amount of light opaque
post-soldering residue that is non-conductive and non-
corrosive, and won’t cause electrical shorts.
The No Clean name refers to the fact that the board will not
be adversely affected if it isn’t cleaned. It does not mean there
will be no residue.

Sn63/Pb37 WS Solder Wire
This wire uses a water-soluble flux core. It offers great
compatibility with all liquid water-soluble organic flux. It
produces minimal spattering, and will not decompose and
carbonize under prolonged heat. Cleaning flux residue requires
only water rinsing or in-line cleaning after soldering.

This wire is complemented with an RA flux core, strong enough
for excellent tarnish and oxide removal while producing bright
shiny solder joints

therefore can be left on the board or cleaned with one of MG’s
flux removers. (See page 14)
