Product Overview

This Puratronic™ 99.9995% aluminum foil is engineered for applications demanding ultra-high purity and minimal trace impurities. The 0.25mm (0.01in) thickness provides a balance between durability and flexibility, while the annealed treatment ensures uniform softness for easy handling and shaping. The foil’s exceptional 99.9995% metals basis purity makes it suitable for environments where even trace contamination could compromise results. Its consistent composition and smooth surface minimize reactivity, ensuring reliable performance in critical procedures. The foil maintains structural integrity under thermal stress, making it adaptable to various temperature-dependent processes. Its non-magnetic properties further enhance its versatility in specialized applications. The material’s high reflectivity and thermal conductivity properties are preserved through the manufacturing process, offering consistent performance across different experimental setups.

FAQs

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

Annealed aluminum foil undergoes a heat treatment process that softens the material, making it more pliable and easier to shape without cracking. This treatment also relieves internal stresses, resulting in improved uniformity and reduced risk of deformation during handling or temperature changes.

2. How does the 99.9995% purity level affect performance in sensitive applications?

The 99.9995% metals basis purity means the foil contains only 0.0005% trace elements, significantly reducing the risk of contamination or unwanted chemical reactions in sensitive procedures. This level of purity ensures more consistent and reliable results in applications where trace impurities could interfere with outcomes.

3. Can this foil be used in high-temperature applications?

While aluminum foil generally has good thermal conductivity, this specific grade maintains its structural integrity at moderate temperatures. For prolonged exposure to high temperatures, consider the specific thermal limits of aluminum and whether your application requires additional protective measures.

4. What precautions should be taken when handling this high-purity foil?

Always use clean, powder-free gloves when handling to prevent contamination from oils or residues. Store in a dry, controlled environment and avoid contact with reactive chemicals. Use dedicated, non-reactive tools when cutting to maintain the foil’s purity.

5. How does the thickness of 0.25mm compare to standard household aluminum foil?

This 0.25mm foil is approximately 2.5 times thicker than standard household foil (typically 0.01mm), offering greater durability and resistance to tearing while maintaining flexibility. The increased thickness provides better thermal distribution and mechanical strength for laboratory applications.
