Product Overview

This Puratronic™ aluminum foil delivers exceptional purity at 99.998% (metals basis), making it ideal for applications demanding ultra-low impurity levels. The 0.5mm (0.02in) thickness provides a robust yet flexible material with outstanding thermal and electrical conductivity, ensuring reliable performance in critical environments. Its high corrosion resistance extends longevity, while the uniform surface finish minimizes contamination risks. The foil’s consistent composition and dimensional stability make it suitable for precision tasks where material integrity is paramount. Available in three practical sizes—100x500mm, 100x100mm, and 50x50mm—it adapts to diverse experimental or industrial setups. Engineered for minimal trace element interference, this foil maintains purity even under extreme conditions, supporting reproducible results. Its malleability allows easy cutting or shaping without compromising structural integrity, while the Puratronic™ grade guarantees compliance with stringent quality standards. Whether used as a protective barrier, conductive layer, or analytical substrate, this aluminum foil ensures optimal performance in sensitive applications.

FAQs

1. What is the difference between Puratronic™ and standard aluminum foil?

Puratronic™ aluminum foil undergoes rigorous purification to achieve 99.998% metals basis purity, significantly reducing trace impurities like iron, silicon, and copper compared to standard foils. This makes it suitable for applications where contamination could skew results or degrade performance.

2. Can this foil be used in high-temperature environments?

Yes, the 0.5mm thickness and high-purity composition allow it to withstand temperatures up to 600°C without significant oxidation or structural failure, though prolonged exposure may affect surface properties.

3. Is this foil compatible with acidic or alkaline solutions?

While aluminum naturally resists mild corrosives, prolonged contact with strong acids (e.g., hydrochloric) or bases (e.g., sodium hydroxide) may cause pitting or dissolution. For such applications, consider a protective coating or alternative materials like PTFE-lined foils.

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

Store in a dry, sealed container away from moisture and reactive gases. Avoid direct contact with other metals to prevent galvanic corrosion. Original packaging is ideal for long-term storage.

5. Are there thinner or thicker alternatives available in the same purity grade?

Thinner Puratronic™ foils (e.g., 0.1mm or 0.2mm) are available for applications requiring flexibility, while thicker sheets (1mm+) offer enhanced rigidity. Check product listings for specific dimensions in the same 99.998% purity range.
