Product Overview

This 99.9995% pure annealed aluminum foil is engineered for applications demanding ultra-low impurity levels, ensuring reliable results in critical laboratory environments. The 0.25mm thickness provides optimal balance between flexibility and durability, making it suitable for handling delicate samples or creating custom barriers. The Puratronic grade guarantees minimal trace element contamination, which is essential for analytical chemistry, material science, and advanced research protocols. The foil undergoes precise annealing to enhance malleability without compromising structural integrity, allowing for easy cutting and shaping. Its uniform surface finish prevents unwanted reactions with sensitive substances, while the high thermal conductivity supports consistent heat distribution in experimental setups. Available in three practical dimensions (100x500mm, 100x100mm, 50x50mm), this foil adapts to various scale requirements from micro-analysis to larger-scale procedures. The material’s resistance to oxidation and corrosion extends its usability across repeated experiments, reducing the need for frequent replacements. Whether used as a protective layer, sample holder, or reaction surface, this aluminum foil maintains performance stability under varying temperature and chemical conditions.

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, improving flexibility and reducing internal stresses. This makes it easier to cut, fold, and shape without cracking compared to non-annealed foil, which retains higher rigidity and may be prone to brittleness in precision applications.

2. Can this foil be used with acidic or alkaline solutions?

The 99.9995% purity level provides good resistance to mild acids and bases, but prolonged exposure to strong corrosive agents may still degrade the surface. For highly reactive substances, pre-testing with small samples is recommended to assess compatibility with your specific chemical environment.

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

Store the foil in its original packaging or a sealed container in a cool, dry environment away from direct sunlight and moisture. Avoid contact with abrasive materials or sharp objects that could scratch the surface, as this may introduce contaminants or compromise its protective properties.

4. Is this foil suitable for high-temperature applications?

The foil can withstand moderate temperatures up to approximately 200°C without significant structural changes. For applications exceeding this range, consider the duration of exposure and potential oxidation effects, as prolonged high heat may alter surface properties or introduce minor discoloration.

5. What alternatives exist if I need thinner or thicker aluminum foil?

For thinner requirements, consider 0.025mm or 0.1mm Puratronic-grade foils, which offer similar purity but with increased flexibility. Thicker options like 0.5mm or 1.0mm are available for applications needing enhanced rigidity, though these may require specialized cutting tools for precise shaping.
