Indium foils, wires, pre-cuts and sealings

Indium features a high ductility – under low pressure it adapts even to smallest irregularities of the ground. This and its low tendency to embrittle (also at extremely low temperatures) makes indium wire a favoured sealing compound for cryotechnoligy (indium gaskets) and vacuum technique.

Materials which extend and contract differently (for instance copper and glass) can be bonded to indium wire thanks to its ductility. Thus these special requirements which are very common in the vacuum technique and cryotechnology ranges can be met much better than with many other sealing materials.

The low melting point of indium wire allows also the use for instance in the soldering range of temperature-sensitive applications.

Indium foils

Forms of delivery

Haines & Masssen stock always indium foil and indium sheet of various sizes. The usual available thiknesses are:

  • 0.05 mm
  • .,1 mm
  • 0.125 mm
  • 0.2 mm
  • .,5 mm
  • 1.0 mm


We supply indium foils with a purity of 99,99+%, thus offering the best compromise between low impurities and an adequate hardness for rolling and even thickness. This purity is also less sensitive to a “pushing through” than ultra-pure qualities.


In order to ensure that you will receive our indium foil / indium sheet in a perfect condition they are sealed under vacuum in a special packing, thus avoiding mechanical and chemical impairments of the quality. For an easier taking out our mini foils (see above photo) are arrayed on a carrier and thermo foiled safely positioned.

Pre-cuts and custom made parts

If you have custom needs, please let us know. Sen us your technical drawing and further requirements just as standards to meet.

Indium wire

Forms of delivery

In our warehouse in Bonn we stock always indium wire in 5-m and 10-m coils which are especially popular for indium gaskets in the vacuum- resp. cryotechnology. The usual available diameters of indium wire are:

  • 0.5 mm
  • 0.69 mm
  • 0.8 mm
  • 1.0 mm
  • 1.27 mm
  • 1.5 mm
  • 1.8 mm
  • 2.0 mm
  • 2.5 mm
  • 3.0 mm


Usually our indium wire has got a purity of 99.99 %. If indium wire with a purity of 99.999 % is required for your purposes we are also able to supply this quality.


In order to ensure that you will receive our product in a perfect condition we supply our indium wire coiled up on a spool in a plastic can shrink-wrapped without dents.

Custom made

Other customer-specific diameters may be realised depending on the required quantities.
