1. What is Indium Metal Wire?
Indium Metal Wire is a high-purity metallic indium product manufactured in wire form for applications requiring a soft, ductile, electrically conductive, and thermally conductive metal. Its low melting point and high malleability make it suitable for soldering, sealing, thermal management, electronics, semiconductor assembly, and other specialized applications.
2. What purity is available for Indium Metal Wire?
Indium Metal Wire is available in different purity grades depending on the application and impurity-control requirements. Common refined indium grades include 99.99% (4N), 99.995% (4N5), and 99.999% (5N). ASTM B1002 also specifies refined indium grades and permits indium with purity up to 99.999% to be fabricated into wire and other forms.
3. What is Indium Metal Wire used for?
Indium Metal Wire is used in low-temperature soldering, hermetic sealing, thermal management, semiconductor packaging, electronic assembly, and other applications requiring a soft and conformable metal. Its low melting point of approximately 156.6°C and good thermal and electrical conductivity make it useful where controlled melting, reliable contact, or thermal transfer is required.
4. How do I choose Indium Metal Wire?
When choosing Indium Metal Wire, consider the required purity, wire diameter, length, application temperature, mechanical requirements, and intended use. For soldering or sealing applications, melting behavior and ductility are important, while electronic and thermal applications may require tighter control of purity and dimensions. The wire should be selected according to the specific application and processing requirements.
5. Can Indium Metal Wire be customized?
Yes. Indium Metal Wire can be customized according to required purity, diameter, length, surface condition, and packaging requirements. Custom wire dimensions can be specified for applications such as sealing, soldering, thermal management, and electronic assembly. Indium wire may also be supplied on spools or cut to specified lengths, depending on the requirements.
6. What sizes and specifications are available for Indium Metal Wire?
Indium Metal Wire can be supplied in different diameters, lengths, and packaging formats. Depending on the supplier and application, wire can be produced to specified dimensions and tolerances, with options such as spooled wire or cut-to-length pieces. For custom requirements, the desired diameter, length, purity, tolerance, and packaging should be confirmed before production.
