Formula: Al 99/Si 1
Form: Foil/Film/Sheet
Material: Aluminum/Silicon
Commodity: Alloys
Temper:
As Rolled
Aluminum/Silicon Alloy Foil (Al99/Si1) combines ultra-high aluminum purity with a minimal silicon addition, resulting in a foil with excellent electrical conductivity, corrosion resistance, and formability. The low silicon content enhances mechanical stability without significantly compromising conductivity, making it suitable for precision electrical and thermal applications. Industries such as electronics, renewable energy, and automotive make use of this alloy for components requiring both lightweight efficiency and reliable surface integrity. Specific applications include current collector foils in battery technologies, heat dissipation layers in semiconductor modules, and corrosion-resistant shielding in sensitive electronic assemblies. In research, it is pivotal in studies on the effects of microalloying on foil performance, surface oxide stability, and forming processes for ultra-thin metallic sheets. Its combination of conductivity, resistance to environmental degradation, and ease of processing solidifies its value in advanced industrial and scientific contexts.
