Typical tin alloys & their areas of application
The areas of application for tin alloys depend heavily on their chemical composition. Depending on the addition of metals such as silver, copper, antimony, bismuth or indium, the physical, electrical and mechanical properties change - and so do the applications.
| Tin-copper alloys | Tin-silver-copper alloys (SnAgCu) | Tin-antimony alloys | Tin-bismuth alloys | Tin-indium alloys | |
|---|---|---|---|---|---|
| Examples | Sn97Cu3 | SAC305 (Sn96,5Ag3,0Cu0,5) | Sn90Sb10 | Bi58Sn42 | In52Sn48 |
| Areas of application | Sanitary, heating and drinking water installations General soldering work Electronics Tinsmithing | Electronics industry (a pioneer of lead-free soldering) Wave soldering processes (wave & selective soldering systems) Printed circuit board assembly Cable assembly | sinker holders (modules for stitch-bonding machines) Mechanical engineering (warp knitting and knitting machines) Lead-free material for technical textile machines | Low-temperature soldering for e.g. thermal fuses Processing of temperature-sensitive components Secondary soldering in the field of electronics production | Low-temperature soldering for e.g. thermal fuses Processing of temperature-sensitive components Secondary soldering in the field of electronics production |
| Properties | Corrosion resistance good wetting wide range of applications lead-free & RoHS-compliant | good electrical conductivity good wetting & good solder penetration lead-free & RoHS-compliant | high wear resistance good mechanical strength lead-free & RoHS-compliant | low melting point (139 °C) eutectic ideal for thermally sensitive materials lead-free & RoHS compliant | low melting point (118 °C) eutectic ideal for thermally sensitive materials fewer physical restrictions than BiSn systems lead-free & RoHS compliant |
The right format for your process
Tin alloys are required in various formats depending on the application and processing step. Whether as ingots for the foundry, wire for precise soldering processes or granulate for automatic dosing systems - we supply the right format for your process. Our portfolio also includes anodes and rods in special dimensions. Our focus is always on quality and processability.
Typical areas of application
Tin is corrosion-resistant, conductive, easy to form and can be alloyed excellently with other metals. These properties make tin alloys a sought-after material in electronics production, surface technology, mechanical engineering and the automotive industry. They ensure stable connections, reliable coatings and safe processes - even under high demands.
GreenTin+
Pure tin made from 100% recycled material
GreenTin+ is an ecologically sourced material of the highest quality that can be purchased as pure tin in the form of bars, rods, wires and anodes.
Alternatively, it is also available as the main alloy component in all relevant lead-free electronic solders.
Giving old metals a new use
For real sustainabilityWe convert metal waste into customer-specific alloys and thus close the loop. In this way, we not only relieve our customers of the burden of disposing of old materials in a proper and environmentally friendly manner, but also make an important contribution to conserving limited resources through recycling.
