Product Overview

This Puratronic™ 99.9999% (6N) annealed aluminum wire is engineered for applications demanding ultra-high purity and consistency. The 1.0mm (0.04in) diameter wire undergoes rigorous annealing to ensure optimal ductility and minimal internal stress, making it ideal for precision electrical connections, thermal conductivity experiments, and analytical instrumentation. The Puratronic™ grade guarantees a metals basis purity of 99.9999%, with trace impurities controlled to parts-per-million levels, ensuring reliable performance in sensitive environments. The wire’s uniform composition and smooth surface finish reduce variability in experimental results, while its malleability allows for easy shaping without compromising structural integrity. Compatible with standard lab equipment, this wire is packaged in protective spools to prevent oxidation and contamination during storage. Whether used in low-temperature physics, semiconductor research, or calibration standards, its exceptional purity and mechanical properties provide a dependable foundation for high-accuracy work.

FAQs

1. What is the difference between annealed and non-annealed aluminum wire?

Annealing is a heat treatment process that softens the aluminum, improving its ductility and reducing internal stresses. This makes the wire easier to bend and shape without breaking, while also enhancing its electrical and thermal conductivity compared to non-annealed wire.

2. Can this wire be used for high-temperature applications?

While aluminum has a melting point of approximately 660°C, prolonged exposure to high temperatures can affect its mechanical properties. For short-term use or applications below 200°C, this wire performs well, but for sustained high-temperature environments, consider alternatives like tungsten or nickel alloys.

3. How should I store this wire to maintain its purity?

Store the wire in its original packaging or an airtight container in a cool, dry environment. Avoid exposure to moisture or corrosive gases, as these can degrade the surface purity. If long-term storage is required, use a desiccant to absorb any residual humidity.

4. Is this wire compatible with soldering or welding?

Yes, this high-purity aluminum wire can be soldered or welded, but it requires specific fluxes or inert gas shielding due to aluminum’s rapid oxide formation. Use aluminum-compatible solder and a high-temperature soldering iron for best results, or TIG welding with argon gas for stronger joints.

5. What alternatives are available if I need a different purity level?

If 99.9999% purity is excessive for your application, consider lower-grade aluminum wires (e.g., 99.99% or 99.5%) for cost savings. For higher purity requirements, 99.99999% (7N) aluminum wire is available but may have limited availability and higher costs.
