High purity aluminum mainly the anode foil for electrolytic capacitor, capacitor, integrated circuit lead wires, the stability of the vacuum evaporation materials, superconducting conductor, disk alloy and high fracture toughness aluminum alloy matrix metal, and in scientific research, chemical industry and so on special purpose.

Ultra high purity aluminum has many good properties, wide range of USES. It is better than the original aluminum conductive, ductility, reflectivity, and corrosion resistance, in the electronic industry, aerospace industry, etc has a wide range of USES. N5 5-6 n super high purity aluminum (0.4 PPM) 96% maximum for each impurity content for semiconductor device manufacturing industry, 4% used for stabilization of superconducting cable materials.

In the manufacturing of integrated circuit chips when cathode sputtering is an indispensable process, this is a special kind of high technology, evaporation in the plasma state of aluminum deposited on the cathode target surface, namely on the silicon to form a thin layer of uniform few defects of aluminum film, then a photosensitive resin layer on the membrane, after exposure to remove the useless part of photosensitive resin, namely also is the place of the resin corrosion, and keep very narrow conductive aluminum strip is required. The pure cathode sputtering with aluminum is, the conductivity will be another important use of superb high purity aluminum as integrated circuit wiring. Ultra trace impurities in high purity aluminum uranium and thorium are as little as possible, because they are radioactive elements, in every release of alpha particles, resulting in the integrated circuit malfunction, make the program error and confusion. TADE production of n2 in high purity aluminum U + 5 Th < 5 PPB (wt %), 5 n5 in ultra high purity aluminum U + Th < 1 PPB (wt %).

5 n and n5 big size plate material, large-scale application in the PDP and TFT - LCD flat panel display, solar cells coated with sputtering target materials. Target plate of raw materials in Fe, Si, Cu, V, Ti and other impurities completely conform to the relevant standards. In the field of superconducting, ultra high purity aluminium is used as the stabilization superconducting cable materials.

5 n in the field of electronic ultrapure aluminum used in the manufacture of photoelectron storage media, such as CD, cd-rom, cd-rw, data plate or mini disc, DVD silver plate, etc., in silver plate with 5 n super pure aluminum sputtering film as reflector of light. Very few impurity content in ultra pure aluminium.

Impurity content rarely made of super pure aluminium has some special advantages

Typical performance characteristics

1. No impurity element content is extremely low. The lower content of impurity elements, the smaller the density of intermetallic compounds

2. Good electrical conductivity. 3 RRR value is high, in the extremely low temperature resistance is very small.

3. The light reflection performance is very strong, has high reflectivity to uv light!
