High purity aluminum sheet is an aluminum sheet product with very high aluminum content, which is usually above 99.00% or even up to 99.99%. This kind of aluminum sheet has good physical and chemical properties due to its high purity and is widely used in many fields.
High purity aluminum sheet usually refers to 1000 series aluminum sheet, which is industrially pure aluminum. These grades have a very high aluminum content, usually no less than 99.0%, and some can be 99.5% or higher. Below are a few common grades of high purity aluminum sheet:
– 1050 aluminum sheet: aluminum content ≥ 99.5%, with good electrical conductivity, thermal conductivity and corrosion resistance, widely used in the electrical and chemical industries.
– 1060 aluminum sheet: aluminum content ≥ 99.60%, also has excellent electrical conductivity, thermal conductivity and corrosion resistance, is one of the most widely used pure aluminum.
– 1070 aluminum sheet: aluminum content ≥ 99.70%, suitable for the higher purity requirements of aluminum occasions.
– 1100 aluminum sheet: Aluminum content ≥ 99.00%, slightly higher strength than 1050 and 1060, but still maintains good formability and weldability, suitable for food processing, chemical processing and other fields.
– 1350 aluminum sheet: mainly used for electrical applications such as wires and cables, aluminum content ≥99.5%.
– 99.99 aluminum sheet: ultra-high purity aluminum, commonly used in high-end electronic products, vacuum coating and so on.
Features of high purity aluminum sheet are:
– Excellent electrical conductivity: high purity aluminum sheet has good electrical conductivity and is suitable for use in the electrical and electronic industries.
– Excellent corrosion resistance: due to the chemical properties of aluminum, especially high purity aluminum, can form a protective oxide film in the wet environment, thus resisting corrosion.
– Light weight and high strength: aluminum’s low density and light weight make it easy to transport and process.
– Good processability: high purity aluminum sheet is easy to form and process and is suitable for a wide range of manufacturing processes.
– Good thermal conductivity: Suitable for applications requiring rapid heat dissipation.
Because of the high purity aluminum sheet higher aluminum content, so the material is relatively soft, and is not suitable for the production of thick plates, the thickest general can only do about 4mm. This kind of aluminum sheet is widely used in fields such as chemical equipment, radiators, decorative materials, etc., especially in the case of high requirements for corrosion resistance.
– Electronic industry: used in the manufacture of electrical contact parts, conductive materials, radiators, etc..
– Chemical industry: used in chemical reaction vessels, storage tanks, etc. due to its corrosion resistance.
– Aerospace: for components of high-end aircraft and spacecraft.
– Food and pharmaceuticals: used in food processing equipment and pharmaceutical packaging materials.
– Optical applications: used in the manufacture of mirrors, optical instruments, etc.
High purity aluminum sheet is a sheet with a high purity aluminum base material, which is ideal for many industries due to its excellent performance and wide range of applications. Choosing the right grade and specification can be done according to the specific application requirements.
