Product Name – Aluminum wire, 1.5mm (0.059in) dia, annealed, Puratronic™, 99.999% (metals basis) Quantity/Pack Size – 1m, 5m Form – Wire (annealed) Grade – Puratronic™ (99.999% metals basis) Application – High-conductivity electrical connections, thermal experiments, corrosion studies

Product Overview

This Puratronic™ aluminum wire delivers exceptional purity at 99.999% (metals basis), making it ideal for applications demanding minimal impurity interference. The 1.5mm (0.059in) diameter provides optimal balance between flexibility and current-carrying capacity, while the annealed treatment ensures superior malleability for precise shaping without compromising structural integrity. The ultra-high purity grade eliminates trace contaminants that could affect experimental results, particularly in electrochemical studies or semiconductor research. The wire’s uniform composition guarantees consistent electrical conductivity and thermal performance across its entire length. Each spool undergoes rigorous quality control to maintain the specified purity level, with certification available upon request. The annealed state reduces internal stresses, preventing work hardening during manipulation. This wire maintains its properties across a wide temperature range, making it suitable for both cryogenic and elevated temperature applications. The smooth surface finish minimizes oxidation risks during storage and handling.

FAQs

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

Annealed aluminum wire undergoes a controlled heating and cooling process that softens the material, increasing ductility and reducing brittleness compared to non-annealed wire. This makes it easier to bend and shape without cracking while maintaining electrical conductivity.

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

The wire maintains structural integrity up to approximately 400°C, though prolonged exposure to high temperatures may affect surface oxidation. For continuous high-temperature use, consider protective coatings or inert atmospheres to preserve performance.

3. How should this aluminum wire be stored to prevent oxidation?

Store in a cool, dry environment with desiccant packets in sealed containers. Avoid exposure to moisture or corrosive atmospheres. For long-term storage, vacuum sealing or argon purging can further prevent surface oxidation.

4. What alternatives exist for applications requiring higher conductivity?

For superior electrical conductivity, consider copper wire (IACS 100% vs aluminum’s ~61%), though it comes with higher density and cost. Silver-plated copper offers the highest conductivity but at significantly greater expense.

5. Is this wire compatible with standard wire connectors?

Yes, the 1.5mm diameter works with most standard terminal blocks and connectors. For crimping applications, use connectors designed for aluminum to prevent cold flow issues that can occur with improper termination.
