Indium wire is used for vacuum and cryogenic compression seals, low-temperature soldering, and custom research assemblies. The grade and diameter depend on the joint and operating conditions.
MetalsTek offers indium wire in 99.99%–99.999% purity and 0.25–6.00 mm diameters. Custom dimensions can be requested; availability and tolerances are confirmed in the quotation.
Pure indium melts at approximately 156.6°C. Indium alloys have different melting characteristics, so specify the composition for soldering applications.
No. A compression seal relies on deformation of the wire between prepared mating surfaces. Soldering is a separate process that melts the joining material.
Indium products can be subject to export licensing and destination-specific requirements. MetalsTek has the capability to arrange compliant exports and support short lead times when the required documentation and approvals are in place. Share your destination and specifications so we can confirm the applicable requirements and schedule.
Send the required purity, diameter and tolerance, quantity, application, delivery destination, and any drawing or documentation requirements. MetalsTek can then confirm availability, export steps, and expected lead time.
MetalsTek indium wire is vacuum sealed and externally labeled for identification. Keep the wire in its original packaging until use, protect it from deformation and contamination, and handle it with clean gloves or tools.
Confirm any special packaging, labeling or documentation requirements with your order.
