LEADED SOLDER WIRE
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.
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.
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.
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,

LEAD-FREE
SOLDER WIRE
SAC305
The SAC305 electronics-grade solder wire series is the predominantly-used lead-free alloy composition that meets J-STD-004 and
J-STD-006 specifications.
These SAC305 wires achieve a consistent solder and flux percentage through a state-of-the-art extrusion wire-drawing machine.
This machine continually monitors the wire to prevent voids and ensure consistency, providing a top-grade solder wire.
All of our SAC305 cored wires are RoHS compliant.
SAC305 RA Solder Wire
A SAC305 complemented with a rosin activated (RA), medium
activity flux. RA Flux residue is non-corrosive and non-conductive,
and therefore can be left on the board or cleaned with one of
MG’s flux removers. (see page 14)
This wire is also REACH compliant.
SAC305 NC Solder Wire
This lead-free wire is complemented with a no-clean,
synthetically refined, splatter-proof resin flux core. Mild
enough to not require cleaning, it leaves a small amount
of post-soldering residue that is non-conductive and non-
corrosive, and won’t cause electrical shorts. The name No
Clean refers to the fact that the flux residues are not harmful
to assemblies and does not mean there will be no residue.
Sn99
Sn99 NC, Halogen Free Solder Wire
MG Chemicals Sn99 Lead-Free Solder is an electronics-grade solder wire. It uses a high-purity eutectic Sn99.3/Cu0.7 alloy, which
is complemented with a no-clean, synthetically refined, splatter-proof resin flux core. It wets and spreads like an RA type flux and
is virtually non-splattering. This solder meets J-STD-004 and exceeds J-STD-006 specifications.
This wire is a great lead-free alternative to leaded solders and serves as an economical substitute for the SAC305 alloy solders. It
leaves a small amount of post-soldering residue that is non-conductive and non-corrosiv.e. The No Clean name refers to the fact
that the flux residues are not harmful to assemblies and does not mean there will be no residue.

LEAD-FREE
CORED WIRE
Sn100e
MG Chemicals’ Sn100e series offers electronics-grade solder wires that use a high-purity eutectic tin/copper/cobalt alloy. They are
a great lead-free alternative to leaded solders and generally provide better wetting, contact angle, flow and visual appearance than
typical Sn63/Pb37 while still delivering excellent performance characteristics. This alloy provides superior solder penetration into
plated through-holes and is a suitable replacement for SAC305 solder as it forms brighter, shinier and less grainy joints, and is less
expensive.
Our Sn100e solder wires meet J-STD-004 and exceed J-STD-006 specifications.
These solder wires achieve a consistent solder and flux percentage thanks to our state-of-the-art extrusion wire-drawing machine.
This machine continually monitors the wire to prevent voids and ensure consistency, providing a top-grade solder wire.
Sn100e RA Solder Wire
This Sn100e Lead Free RA Solder is complemented with a
rosin activated, medium activity flux that is classified as ROM1
according to J-STD-004B.
This solder is ideal for through-hole and surface mount
interconnects. It is a suitable replacement for SAC305 solder
since the 494x forms brighter, shinier and less grainy joints.
Furthermore, it is less expensive than SAC305.
Sn100e NC Solder Wire
This wire features a no-clean, synthetically refined, splatter-
proof resin flux core. It is fast wetting, fast flowing and low
VOC.
Mild enough to not require cleaning, it leaves a small amount
of post-soldering residue that is non-conductive and non-
corrosive and won't cause electrical shorts.
The name No Clean refers to the fact that the flux residues are
not harmful to assemblies and does not mean there will be no
residues.
