Product Overview
This ultra-pure indium foil delivers exceptional conductivity and minimal impurity interference, making it a critical component for advanced laboratory and industrial applications. The 0.25mm thickness provides optimal flexibility while maintaining structural integrity, ensuring consistent performance in demanding environments. Manufactured to Puratronic™ standards, this 99.9975% pure indium (metals basis) meets the rigorous requirements of semiconductor fabrication, thermal management systems, and specialized research applications. The foil’s uniform composition and surface finish eliminate variability in experimental results, while its malleability allows for precise shaping and customization. Available in standard 100x100mm and 50x50mm dimensions, this indium foil offers researchers and engineers a reliable material solution where trace impurities could compromise performance. The material’s low melting point (156.6°C) and excellent adhesion properties make it particularly valuable in applications requiring thermal bonding or electrical contacts. Each piece undergoes stringent quality control to ensure consistency across batches, providing users with confidence in their experimental setups and production processes.
FAQs
1. What is the typical surface finish of this indium foil?
The foil features a smooth, uniform surface finish optimized for direct application in electronic and thermal interfaces. The manufacturing process ensures minimal surface oxidation while maintaining the material’s inherent properties.
2. Can this indium foil be soldered directly to other metals?
Yes, the high-purity composition allows for excellent wetting characteristics with common solder alloys. The foil’s purity level minimizes the formation of brittle intermetallic compounds that could compromise joint integrity.
3. What storage conditions are recommended to maintain the foil’s properties?
Store in a cool, dry environment with controlled humidity levels (below 50% RH) and away from direct sunlight. Original packaging provides adequate protection against oxidation when not in use.
4. How does the Puratronic™ grade differ from standard indium foil?
The Puratronic™ designation indicates a significantly higher purity level (99.9975%) compared to commercial grades, with stricter controls on trace metal impurities that could affect electrical or thermal performance.
5. Is this foil compatible with vacuum deposition processes?
The ultra-low impurity profile and consistent composition make this indium foil highly suitable for vacuum deposition applications, where even trace contaminants could affect thin-film quality.
