Product Overview

This Puratronic™ 99.999% aluminum wire is engineered for applications demanding ultra-high purity and consistent performance. The 1.0mm diameter annealed wire ensures exceptional malleability and conductivity, making it suitable for critical laboratory and industrial uses where trace impurities can compromise results. The wire undergoes rigorous purification processes to achieve a metals basis purity of 99.999%, eliminating common contaminants like iron, silicon, and copper that could interfere with sensitive experiments or manufacturing processes. Its annealed state enhances ductility, allowing for precise shaping without compromising structural integrity. The uniform diameter and surface finish ensure reliable performance in electrical conductivity tests, thermal management systems, and as a reference material in analytical chemistry. The wire is supplied in a protective spool to prevent oxidation and physical damage during storage and handling. Whether used in research settings or specialized manufacturing, this aluminum wire delivers the consistency and purity required for high-stakes applications where material reliability is non-negotiable.

FAQs

1. What does the “annealed” property indicate for this aluminum wire?

The annealed state means the wire has been heat-treated to reduce hardness and increase ductility. This makes it easier to bend, shape, or draw without breaking, while maintaining its electrical and thermal conductivity properties. It also relieves internal stresses from the manufacturing process, ensuring uniform performance.

2. How does the 99.999% purity compare to standard aluminum wire grades?

Standard aluminum wire typically ranges between 99.0% and 99.7% purity, containing higher levels of impurities like iron, silicon, and magnesium. This 99.999% Puratronic™ grade eliminates virtually all trace elements, making it ideal for applications where even minor contaminants could skew results, such as in semiconductor manufacturing or high-precision electrical testing.

3. Is this wire compatible with soldering or welding processes?

Yes, the high purity and annealed nature of this wire make it suitable for soldering and welding, though the choice of flux or filler material should be selected based on the specific application. The absence of oxides and contaminants ensures cleaner joints, but proper surface preparation and temperature control are still required to avoid introducing new impurities.

4. What storage conditions are recommended to maintain the wire’s purity?

Store the wire in its original packaging or a sealed container in a cool, dry environment with minimal humidity. Avoid exposure to corrosive gases or liquids, as even high-purity aluminum can develop surface oxides over time. If long-term storage is needed, consider using desiccants or inert gas purging to prevent oxidation.

5. Are there alternatives to this wire for applications requiring slightly lower purity?

For applications where 99.999% purity is excessive, consider aluminum wires with 99.9% or 99.5% purity, which are more cost-effective while still offering good conductivity and corrosion resistance. However, these grades may contain higher levels of impurities that could affect performance in sensitive applications, so always verify compatibility with your specific use case.
