Indium wire from Indium Corporation is manufactured to demanding quality standards. Our flexible manufacturing process allows us to fulfill orders from evaluation/research quantities to full-scale production volumes.
Indium Wire Diameters
Capabilities range from .001" (0.025mm) diameter to .250" (6.35mm) and larger. Actual dimensions achievable are subject to the properties of each metal.
We have developed standard tolerances but can work with you to accommodate any special requirements. Standard tolerances are:
| Diameter | Standard Tolerance |
|---|---|
| Up to .002" (.050mm) | ±.0005" (.0127mm) |
| >.002" (.050mm) to .010" (.254mm) | ±.001" (.025mm) |
| >.010" (.254mm) to .060" (1.52mm) | ±.002" (.050mm) |
| >.060" (1.52mm) to .250" (6.35mm) | ±.003" (.076mm) |
| >.250" (6.35mm) | ±2.5% |
Packaging
Indium wire is packaged on spools. We can create specialized packaging to meet specific needs, such as spool size, quantity per spool, or other requirements.

Storage
The shelf life of indium wire is determined by the alloy and its resistance to oxidation, as well as the storage container and the conditions in which it is stored.
To increase storage time, and keep surface oxidation to a minimum, store wire tightly closed in the original container in 55% RH or less, and at temperatures below 22°C. Wire can also be stored in an inert atmosphere, such as a nitrogen dry box.
Delivery
Short lead times enable you to get your order in time to meet your production schedule.
Each order can be shipped with a Certificate of Analysis, which includes information on metallic impurities. We can also provide a Certificate of Conformance when indium wire is made to customer specifications.
Technical and Customer Support
Indium Corporation’s internationally experienced engineers provide in-depth technical assistance to our customers. Thoroughly knowledgeable not only in indium wire, but all facets of Material Science as it applies to the electronics and semiconductor sectors, Technical Support Engineers provide expert advice in solder properties, alloy compatibility and selection of solder preforms, wire, ribbon and paste. Indium Corporation’s Technical Support engineers provide Rapid Response to all technical inquiries.
Available Materials
Over 100 alloys can be made into wire, including pure indium and indium alloys, lead-free alloys, gold/tin, tin/lead and bismuth alloys, as well as many other combinations. Melting temperatures range from 47°C (117°F) to over 364°C (687°F). We can also custom design alloys for your application.
