Aluminum Rod

Aluminium Rod is available in purities from 99% (2N) to 99.999% (5N) in the as-drawn condition, spanning the full range from general industrial rod through to ultra-high purity research stock, with the as-drawn temper providing improved mechanical strength over annealed material across all grades. The purity level determines the application: at 2N and 3N grades, the rod serves in general engineering, heat sink fabrication, structural fixtures, and electrical conductor applications where aluminium's low density, good thermal conductivity, and easy machinability are the primary design drivers. At 4N, reduced trace impurity content suits precision optical mounts, thin-film deposition substrates, and electronics hardware where surface chemistry and contamination control begin to matter. At 5N purity, aluminium rod is used as evaporation source stock for physical vapour deposition, as a reference material in analytical chemistry, as a model face-centred cubic metal in fundamental materials science studies of deformation, recrystallisation, and grain boundary behaviour, and in semiconductor processing applications where ultra-low contamination is a process requirement. The as-drawn condition delivers higher tensile strength than annealed stock across all grades, providing better dimensional stability and resistance to deformation during machining and assembly. Across the full range, aluminium's self-healing oxide film provides reliable atmospheric corrosion resistance without surface treatment.
