High purity aluminum wire is supplied in continuous spool form for thermal evaporation, wire bonding, electrochemical research, and custom fabrication. Its clean surface, ductility, and consistent diameter make it suitable for processes where material purity and dimensional control are critical to performance and reproducibility.

Available in purities from 4N (99.99%) through 6N (99.9999%), high purity aluminum wire supports applications requiring low contamination and reliable material feed. GDMS COA included with each shipment.

Most standard items ship within 1–2 business days.

What purity sputtering target do I need for semiconductor applications?
For semiconductor metallization and interconnect layers, 5N (99.999%) is the standard choice. For higher-end applications such as superconducting devices or quantum computing, 6N (99.9999%) targets reduce trace metal contamination to levels required by those processes. 4N targets are suitable for general thin-film coating and decorative applications.
Can I get a bonded sputtering target assembly?
Yes. HPA supplies bonded target assemblies designed to match your specific sputtering tool and process requirements. Contact us with your target design, backing plate specifications, and bonding requirements for a custom quote.
What is the difference between cast and directionally solidified targets?
HPA's super high purity targets (5N and above) are produced using directional solidification in vacuum, not cast. This process prevents inclusions from entering the metal, enabling us to maintain the highest purities. Cast targets at lower purities (4N) are suitable for applications where trace-level contamination is less critical.
What sizes are available and can you make custom sizes?
Stock sizes range from 1" (25mm) to 12" (305mm) in diameter with thicknesses from 0.125" (3.2mm) to 1" (25.4mm). Larger sizes and custom dimensions are available with short lead times. Contact us with your specifications.
