Explore 1000 Series Aluminum Sheet

In the dazzling galaxy of metal materials, 1000-series aluminum sheet is like a pure pearl. With extremely high aluminum content and a series of excellent properties, it plays an indispensable role in many industrial fields. Today, let us unveil the veil of 1000 series aluminum sheet and learn about its casting secrets, performance parameters, market value and ubiquitous applications.

How are 1000 series aluminum sheet cast?

The excellent performance of 1000 series aluminum sheet begins with its sophisticated casting process. It mainly adopts the method of continuous casting combined with hot rolling.

Smelting and refining: High-purity aluminum ingots are strictly smelted and refined through refining processes such as the introduction of inert gas and the addition of flux to remove impurities (mainly iron Fe and silicon Si) to ensure the purity of the aluminum liquid.

Continuous casting: Pure aluminum liquid is continuously cast into thick slabs or large ingots. This process is efficient and energy-saving, and can effectively control the grain structure, laying a good foundation for subsequent processing.

Горячая прокатка: Thick slabs/ingots at high temperatures are gradually thinned to the required thickness through multiple rolling passes. The hot rolling process not only shapes the shape, but more importantly, it refines the grains of the material, significantly improving the strength, plasticity and internal uniformity of the aluminum plate.

Холодная прокатка: For sheet that require higher surface finish, more precise dimensional tolerances or specific mechanical properties, cold rolling and corresponding annealing treatment will be carried out after hot rolling.

This mature casting and rolling process ensures that the 1000 series aluminum plate has excellent processing performance and consistency while maintaining the essential characteristics of high-purity aluminum.

The chemical and physical charm of 1000 series aluminum sheet

The core charm of 1000 series aluminum sheet lies in the unique performance combination brought by their “purity”:

• Excellent corrosion resistance: High-purity aluminum can quickly form a dense and stable aluminum oxide protective film in the air, giving it excellent resistance to corrosion by the atmosphere, water and various chemical media. This is the cornerstone of its application in chemical and marine environments.
• Top thermal conductivity and electrical conductivity: Among all aluminum alloys, 1000 series, especially 1060, 1050, 1100, etc., have the highest thermal conductivity and electrical conductivity, second only to pure copper, and are ideal for manufacturing heat exchangers, radiators, and conductive parts.
• Good processing formability: The extremely high ductility makes it easy to perform cold processing operations such as stamping, stretching, bending, and deep drawing, which is convenient for manufacturing parts with complex shapes.
• High reflectivity: It has good reflective properties for visible light, thermal radiation and electromagnetic waves, and is suitable for lighting fixture reflectors, thermal insulation materials, etc.
• Non-magnetic: It is an excellent material for manufacturing non-magnetic environment equipment.
• Aesthetics: Silvery white metallic luster, various decorative and functional surfaces can be obtained through anodizing.
