The A5 series features high-purity (≥99.0%) small-diameter (3-11nm) carbon nanotubes with excellent conductivity due to its high aspect ratio and specific surface area (250-350m²/g). With very low metal content (Fe <50ppm, Co <800ppm, Ni <15ppm), it is suitable for high-performance applications. Moisture content is maintained at <3500ppm.
