Description
HPA Distribution specializes in Aluminum Evaporation Materials, such as Deposition Pellets and Slugs for Thin Film Coating with Vacuum deposition, PVD (Physical Vapor Deposition,) and Electron Beam deposition processes, and sapphire applications. These deposition materials are for semiconductor and electronic manufacturing applications.
Our High Purity Aluminum Evaporation Pellets are produced by cutting rods of various thicknesses into specific lengths, which are then cleaned with hydrofluoric (HF) solution (about 2%), then washed several times with deionized water before drying. This process produces a consistent size and purity without any contamination. These high purity rods (5N to 6N) are all produced in directional solidification in vacuum to ensure the highest purity products. Pellets are available in 4N6, 5N, 5N5, and 6N purities.
We also have Granules that are produced by dropping molten aluminum through a screen into water for cooling in specific sizes, and while the shape is generally similar, it is not as consistent as Pellets. Granules are only produced in 4N and 4N6 purities, and are generally used for commercial applications due to cost competitiveness.
Disclaimer - these non-lethal products have no military, ammunition, or lethal applications.
