What Is the Highest Purity Aluminum?

The purest form of aluminum is 99.99995%, also known as 6N5 MBE (molecular beam epitaxy) grade. This highest purity level achievable for aluminum is required for single-crystal thin film deposition. About Aluminum Purity Generally, the purity of aluminum is denoted in 'nines.' For instance, 4N (four nines) aluminum is 99.99% purity. This is a popular choice in several industrial applications due to the balance of purity and cost effectiveness. Typical use cases include capacitor foils and high-end electrical components production, where superior conductivity and resistance to corrosion are essential. Most importantly, 4N aluminum has few impurities, which ensures electronic device longevity and high performance. Further up the scale, there is 5N aluminum (99.999%), which contains even fewer impurities than 4N....
