SPI Metal Wires for Evaporation

Let SPI take care of all of your evaporation needs!

Available metal wires:
SPI Supplies offers high purity 8 mil wires of the following precious metals: gold, platinum, palladium, gold/platinum, platinum iridium and silver. All are 8 mil (0.20 mm) diameter wires and are "electron microscope grade" for all SEM and TEM applications. Purity is generally the highest available commercially. In times of wildly fluctuating precious metals prices, email spi3spi@2spi.com for current pricing. Under normal circumstances, the prices that are listed are also current.

Cutting the wire:
Use of a razor blade or other typical cutting instrument tends to "flatten" the cut end of soft precious metal wires, leaving the cut cross-section looking more like an ellipse than a circle. If this is a problem, then we suggest the use of the SPI Snip-It™ Precision Cutting Tool.

Evaporating the wire:
For typical electron microscope laboratory applications, the wire can be evaporated readily via tungsten baskets or in the case of platinum, also from carbon or graphite rods.

Scanning probe tips:
For some appplications, the platinum/iridium wire is the preferred tip material, in 0.008" (0.20 mm) diameter.

SPI Aluminum Wire

Properties of aluminum
CAS#: 7429-90-5
High purity (.9999) fine wire for use in vacuum evaporation applications. For electron microscope laboratory applications, evaporation is usually done from tungsten baskets.

Dimensional specifications:
0.25 mm (10 mils) diameter x 1 meter long.

SPI Tungsten Wire

Properties of tungsten
CAS#: 7440-33-7

Wire specially manufactured for use in vacuum evaporators for the vacuum evaporation of certain metal wires that can be wrapped around this tungsten wire and evaporated as a thin film coating on to small substrates. This is a lower cost alternative than purchasing already-made tungsten baskets. However, some metals, such as gold alloy very quickly with tungsten and while more expensive, the baskets might be the more appropriate choice if the wire fails before sufficient metal has been evaporated. Wire has been pre-cleaned.
