Product Overview
This high-purity indium wire (2.0mm diameter) is manufactured under stringent Puratronic™ standards, ensuring 99.998% metals basis purity with trace impurities reduced to negligible levels. The wire’s uniform diameter and ultra-low impurity profile make it ideal for applications demanding exceptional thermal and electrical conductivity, such as semiconductor bonding, cryogenic sealing, and low-temperature soldering. Indium’s soft, malleable nature allows for easy shaping without compromising structural integrity, while its resistance to oxidation ensures long-term stability in controlled environments. The wire is supplied in precise 1-meter or 25cm lengths, eliminating waste and enabling cost-effective usage for small-scale experiments or bulk production. Its low melting point (156.6°C) further enhances versatility in alloy formulations and thermal interface materials. Rigorous quality control guarantees batch-to-batch consistency, critical for reproducible results in sensitive research and industrial processes.
FAQs
1. What is the maximum operating temperature for this indium wire without degradation?
The wire remains stable up to its melting point of 156.6°C. For prolonged use, temperatures below 120°C are recommended to prevent softening or oxidation over time.
2. Can this wire be used directly for vacuum-sealing applications?
Yes, its high purity and low vapor pressure make it suitable for vacuum environments, though pre-cleaning with acetone is advised to remove surface contaminants.
3. How does the Puratronic™ grade differ from standard indium wire?
Puratronic™ grade ensures 99.998% minimum purity with tightly controlled trace element limits (e.g., <10ppm for Fe, Cu, Pb), whereas standard grades may contain higher impurities affecting performance.
4. Is this wire compatible with lead-free soldering processes?
Absolutely. Its low melting point and high wettability make it a preferred additive in lead-free solder alloys, particularly for electronics requiring RoHS compliance.
5. What storage conditions are recommended to prevent oxidation?
Store in a cool, dry environment (below 25°C) in its original packaging with desiccant. For long-term storage, seal under argon gas to minimize surface oxidation.
