Aluminium (Al) Evaporation Pellets

Aluminium (Al) Evaporation Pellets are a high-purity aluminum material specifically designed for vacuum evaporation processes. They typically boast a purity of 99.9% to 99.9999% to ensure the formation of high-quality thin films during deposition. These pellets exhibit a silvery-white color with a metallic luster, a density of 2.7 g/cm³, a melting point of 660°C, and a thermal conductivity of 235 W/m·K.

During the manufacturing process, the aluminum pellets are produced through ultra-high purification techniques, such as crystallization and solid-state sublimation. Aluminium (Al) Evaporation Pellets are usually cylindrical in shape, with customizable sizes, and common diameters ranging from 1 mm to 10 mm. This morphology facilitates uniform evaporation and deposition rates during the evaporation process.

Aluminium Evaporation Pellets are widely used in various fields. In microelectronics, they are employed to create electrical connections and conductive layers in semiconductor devices. In optics, aluminum thin films are extensively utilized for mirrors and optical components due to their high reflectivity. Additionally, they are used in the production of corrosion-resistant coatings, solar cells, as well as OLED and LCD displays.

Aluminium (Al) Evaporation Pellets offer several advantages. Aluminum possesses excellent electrical conductivity, making it an ideal material for creating thin conductive films. Furthermore, aluminum films form a protective oxide layer in air, providing natural corrosion resistance. The low density of Aluminium (Al) Evaporation Pellets makes them a preferred material for weight-sensitive applications in industries such as aerospace and automotive. Moreover, aluminum is abundant and relatively inexpensive, making it a cost-effective choice for large-scale industrial applications.

In summary, Aluminium (Al) Evaporation Pellets are a high-performance evaporation material suitable for a variety of thin-film deposition applications, capable of delivering high-quality coatings and thin films.

High Purity:
Aluminium Evaporation Pellets are available in purity levels ranging from 99.9% to 99.9999% (3N to 6N), ensuring minimal impurities that could affect film quality. This high purity is critical for applications in semiconductors, microelectronics, and optical coatings, where even trace contaminants can degrade performance. The pellets undergo advanced purification processes such as zone refining and vacuum distillation to achieve ultra-high purity.

Excellent Thermal Conductivity (235 W/m·K):
Aluminum's superior thermal conductivity allows for rapid and uniform heating during evaporation, enabling precise control over deposition rates. This property is essential for consistent film thickness and adhesion, particularly in high-precision optical and electronic applications.

High Reflectivity:
Aluminum thin films exhibit strong reflectivity across visible and infrared spectra, making them ideal for mirrors, solar reflectors, and optical coatings. This property is leveraged in telescopes, laser systems, and energy-efficient lighting.

Corrosion Resistance:
Upon exposure to air, aluminum forms a protective oxide layer, enhancing durability in humid or chemically aggressive environments. This makes it suitable for marine, aerospace, and industrial coatings.
