3N8-4N8 aluminum is mostly used for rolling aluminum foil of electrolytic capacitors, lighting fixtures and data storage. 5N-6N ultra-pure aluminum is mostly used in manufacturing semiconductor devices, manufacturing optoelectronic storage media, superconducting cable stabilization materials, and playing an important role in space shuttle scientific research. The picture below is the microscopic metallographic inspection picture of aluminum sputtering target, the average particle size is <300μm. We produce high-purity aluminum sputtering targets. Its biggest advantage is that in the process of physical vapor deposition, a thin film with excellent conductivity and particle minimization can be obtained. The following table is a certificate of composition analysis of 5N high-purity aluminum sputtering target.
