Formula: Al 99/Si 1
Form: Rod
Material: Aluminum/Silicon
Commodity: Alloys
Aluminum/Silicon Alloy Rod (Al99/Si1) combines ultra-high aluminum purity with a low silicon addition, delivering excellent electrical conductivity, corrosion resistance, and mechanical formability. The minimal silicon content enhances structural stability without significantly reducing ductility, making it suitable for precision-engineered components. This alloy is widely used in electronics, aerospace, and automotive industries. Specific applications include high-purity electrical conductors, precision welding rods for sensitive assemblies, and corrosion-resistant fasteners for marine and aerospace environments. In research, it serves as a model material for studying microalloying effects, grain refinement, and the mechanical-electrical property balance in high-purity aluminum systems. Its combination of conductivity, durability, and adaptability underpins its value in both advanced manufacturing and scientific innovation.
