1100 aluminum sheet belongs to the 1000 series commercial pure aluminum family with aluminum content of at least 99.0%. It is valued for its excellent corrosion resistance, superior formability, and attractive surface finish rather than structural strength.
The alloy performs exceptionally well in bending, spinning, stamping, and deep-drawing operations while maintaining a smooth and consistent appearance. Its combination of fabrication performance and aesthetic quality makes it a popular choice for decorative, architectural, and light industrial applications.
With good thermal conductivity, reliable corrosion resistance, and excellent workability, 1100 aluminum sheet remains one of the most widely used commercial pure aluminum grades worldwide.
The 1100 aluminum sheet is a commercially pure aluminum alloy containing at least 99.0% aluminum content. It is globally recognized for its high ductility, attractive surface finish, superior corrosion resistance, and excellent electrical and thermal conductivity.
Compared to higher-strength alloy plates, pure 1100 aluminum sheet provides exceptional cold-working performance, smooth surface quality, and cost-effective fabrication. It is widely applied in deep-drawn components, decorative panels, thermal insulation cladding, and chemical equipment where maximum structural strength is not the primary engineering goal.
For industrial packaging fabricators and global metal distributors, our factory guarantees consistent alloy purity, custom sheet dimensions, and highly competitive pricing for high-volume orders. All raw material plates strictly adhere to international manufacturing standards such as ASTM B209 specifications.
These ultra-workable pure metal plates are widely utilized across electrical, chemical, architectural, and commercial industries. Typical applications include:
We supply 1100 aluminum sheet products in a broad selection of thicknesses, custom cut-to-size widths, tempers (such as Soft O, H14, H24, H18), and specialized surface treatments to meet precise project demands.
Available surface options include standard mill finish, brushed texture, mirror polished, color-coated, or protective PE/PVC film applications for building construction, automotive transportation, industrial machinery, and OEM fabrication.
Our dedicated manufacturing facility ensures fast dispatch lead times, export-grade seaworthy wooden pallet packaging, and authentic Mill Test Certificates (MTC) with every export shipment to guarantee full quality compliance.
