Yleiskatsaus
High-purity aluminum is silvery white, with a smooth surface, clear crystal lines, and no inclusions. High-purity aluminum has low deformation resistance, high electrical conductivity and good plasticity. It is mainly used in scientific research, electronic industry, chemical industry, manufacturing of high-purity alloys, laser materials and some other special purposes. Products are generally supplied in semi-circular ingots or long plate ingots, and the mass of each semi-circular ingot is not less than 45kg. The mass of each long plate ingot is not more than 25kg, the cross-sectional size of the long plate ingot is generally 200mm*65mm, and the length is not more than 600mm.
Features: Ultra-high purity, extremely low impurities and trace elements, using self-developed crystallization purification technology
Applications: sputtering targets, high-purity alloys, standard samples, electrolytic capacitor anode foils, capacitor leads, integrated circuit conductors, vacuum evaporation materials, superconducting stable conductors, etc.
