Description

Aluminum Silicon Slug, 6.35mm (0.25in) Dia x 6.35mm (0.25in) Length, 99.99% (Metals Basis) is a high-purity, pre-alloyed metallic material supplied in a convenient, uniform slug form. This product is engineered for precision and consistency in advanced manufacturing and research applications where exact dosing and high material purity are critical. It is essential for industries such as aerospace, automotive, and specialized metallurgy that require controlled alloying or additive manufacturing with aluminum-silicon master alloys.

Application

• Master Alloy Production: Used as a precise additive to introduce silicon into aluminum melts, controlling the eutectic structure and improving castability, strength, and thermal properties.
• Additive Manufacturing (3D Printing): Serves as a feedstock material for powder bed fusion or directed energy deposition processes to create high-performance, lightweight aluminum-silicon components.
• Precision Casting: Employed in investment and die-casting foundries to achieve specific alloy compositions with minimal impurity introduction and excellent reproducibility.
• Semiconductor & Thin Film Deposition: Utilized in physical vapor deposition (PVD) processes, such as sputtering targets or evaporation sources, for creating metallization layers or functional coatings.
• Research & Development: Provides a reliable, high-purity source material for developing new aluminum-silicon alloys, composite materials, and conducting controlled experiments in metallurgy and materials science.
• Welding & Brazing: Acts as a filler material or alloying component in specialized welding rods and brazing pastes for joining aluminum components.
