Product Overview
This Puratronic™ indium wire delivers 99.998% minimum purity (metals basis), ensuring ultra-low impurity levels for demanding laboratory and industrial applications. The 1.0mm diameter wire comes annealed for enhanced ductility and workability, eliminating internal stresses that could compromise performance in critical processes. Its exceptional thermal and electrical conductivity makes it ideal for creating reliable thermal interfaces, low-temperature soldering, and semiconductor packaging where contamination control is paramount. The wire’s uniform diameter and smooth surface finish enable precise dispensing and consistent results in automated or manual applications. Packaged in airtight spools to prevent oxidation, this indium wire maintains its purity during storage and handling. The material’s low melting point (156.6°C) combined with its high purity makes it particularly valuable for applications requiring precise thermal management without introducing contaminants. Each batch undergoes rigorous spectroscopic analysis to verify purity levels, with certification available upon request.
FAQs
1. What is the difference between annealed and non-annealed indium wire?
Annealed indium wire undergoes a controlled heating and cooling process that relieves internal stresses, making it significantly more ductile and easier to work with compared to non-annealed wire. This treatment prevents brittleness during forming or bending operations.
2. Can this indium wire be used for vacuum applications?
The 99.998% purity level and Puratronic™ grade make this wire suitable for high-vacuum environments, as it minimizes outgassing that could contaminate vacuum systems or sensitive processes.
3. What precautions should be taken when storing this wire?
Store in its original packaging in a cool, dry environment away from direct sunlight. The wire should be kept sealed when not in use to prevent surface oxidation, which could affect its performance in sensitive applications.
4. Is this wire compatible with lead-free soldering processes?
Yes, this high-purity indium wire serves as an excellent lead-free alternative in soldering applications, particularly where low-temperature joining is required or where indium’s unique properties are beneficial for the joint integrity.
5. How does the wire’s diameter tolerance affect performance?
The 1.0mm diameter is maintained with tight tolerances to ensure consistent material deposition rates, which is critical for automated dispensing systems and processes requiring precise material quantities.
