Durafuse™ LT Low-Temperature Alloy System: The Tough Choice That is Easy to Make
Award-winning Durafuse™ LT is a patented low-temperature alloy system by Indium Corporation designed to provide high-reliability in low-temperature applications that require a reflow temperature below 210°C. Durafuse™ LT provides improved drop shock resilience, outclassing bismuth-tin (BiSn) or bismuth-tin-silver (BiSnAg) alloys, and can perform better than SAC305 with optimal process setup. Durafuse™ LT is made up of a low-melting indium-containing alloy and a higher melting SAC alloy. The SnInAg alloy initiates joint fusion while the SAC alloy provides enhanced strength and durability. Durafuse™ LT is ideal for high-reliability applications that utilize thermally sensitive components or boards and/or have a requirement for step soldering. End-use applications for Durafuse™ LT include handheld mobile devices, computing, automotive, and medical devices.
Durafuse™ LT Delivers:
- Improved drop shock performance more than two orders of magnitude better than bismuth-containing low-temperature materials
- Drop shock performance equal to or better than SAC305 with proper process optimization
- Ideal characteristics for step soldering and low-temperature requirements
- A wide processing window compatible with large temperature gradients

Indium Corporation’s bar solder is manufactured specifically to surpass the strict quality demands of the surface mount industry in order to provide a more consistent and reliable performance. Bar solder is available in the standard Sn62 (Pb-containing) and Pb-free alloys, such as SAC305 and Indalloy 291 (99.25Sn/0.7Cu/0.05Ni/Ge). All bar solder complies with the requirements of ASTEM B-32, J-STD-006, and JIs-Z-3282.
CW-301 is a water-soluble flux-cored wire is optimized for use with SnPb and Pb-free assembly and rework processes. It has minimal spattering and low odor, and is resistant to charring. It wets to common Pb-free surface finishes including: Immersion Sn, ENIG, OSP, and Immersion Ag.
CW-807 is a halogen-free, no-clean flux-cored wire and is our most popular wire because it is compatible with all Indium Corporation’s no-clean solder pastes, wave fluxes, and soft solder alloys. It solders well while still meeting the most recent requirements of J-STD-004B type ROL0. It also passes the more stringent Surface Insulation Resistance (SIR) and Electromigration (ECM) requirements of J-STD-004 revision B.
Indium Corporation is quickly becoming known as one of the highest quality, full-line supplies of flux-cored wire solder. Its flux-cored wire contains flux in the center to facilitate the soldering process and eliminate the need for a separate flux and can be used for robotic soldering, manual soldering, or rework. Indium Corporation uses only “conflict-free” and grade A (per ASTM B32) metals and the materials have been tested and certified to meet IPC J-STD-004B standards. Indium Corporation’s flux-cored wire is well-known for its void-free, evenly layer winding and has a low oxide shiny appearance over time.
CORE 230-RC is one of the newest and most popular flux-cored wire products and features:
- A very fast wetting speed
- Void-free & precision wound
- A low spatter formulation
- Light-colored residue
- Compatibility with Pb-free and SnPb alloys
- IPC J-STD-004 classification: REL0
- IPC J-STD-004B classification: REL1
- Spatter: <1%
- Acid value (mgKOH/gram of flux): 165

Indium10.1 is a supercharged air reflow capable, no-clean, Pb-free solder paste. Similar to Indium8.9HF, it is popular with electronics manufacturers who are able to use halogen-containing materials. Indium10.1 has a high oxidation resistance to virtually eliminate incomplete coalescence (graping) of small deposits and warpage induced head-in-pillow defects. It also offers extremely low, large ground-plane voiding found in QFN, LGA, and DPAK components.
Indium8.9HF is a high-performance Pb-free solder paste and is being used heavily by electronic manufacturers in the automotive, industrial, and medical markets. It is an air reflow capable, no-clean solder paste specifically formulated to accommodate the higher processing temperatures required by SAC and other alloy systems favored by the electronics industry to replace conventional Pb-bearing solders. It offers unprecedented stencil print transfer efficiency to work in the broadest range of processes. This coupled with its low voiding and enhanced SIR/ECM performance attributes make this and ideal solder paste for the vast majority of all electronic manufacturing applications.
NC-SMQ92J is widely known as the best halogen-free SnPb solder paste on the market. It is a halogen-free, air reflow capable, no-clean solder paste formulated for superior manufacturing yields and ICT performance. It provides consistent fine-pitch paste deposition with an excellent stencil life and tack time. It has a soft flux residue for outstanding ICT first pass yield. NC-SMQ92J will surpass all J-STD-004, and J-STD-005 specifications.
