Cell Lab 4N (99.99%) Aluminium (Al) Sputtering Target

High-Purity Aluminium Target for Optical, OLED, and Semiconductor Coatings

General Description

Cell Lab 4N (99.99%) Aluminium Sputtering Target is manufactured from high-purity aluminium metal for consistent thin-film performance. Known for its low density, excellent electrical and thermal conductivity, and high reflectivity, this target is widely used in optical coatings, semiconductor fabrication, and OLED display production.
When sputtered or evaporated under vacuum, aluminium forms a durable, reflective, and corrosion-resistant film, ideal for use in mirrors, telescopes, headlamps, and electronic devices.

Key Features

  • High Purity (99.99%) – Ensures uniform thin-film deposition with minimal contamination.

  • Superior Reflectivity – Ideal for optical mirrors, automotive lighting, and telescopic coatings.

  • Excellent Conductivity – Enables efficient electron and heat transfer in thin-film circuits.

  • Versatile Application – Suitable for DC sputtering systems across multiple industries.

  • Corrosion Resistance – Naturally forms a protective oxide layer during deposition.
