Thin aluminum strips
Thin aluminum strips are precision-rolled aluminum products characterized by their slim thickness and high-quality finish. Widely used in a range of industries, these strips combine the lightweight and corrosion-resistant properties of aluminum with excellent mechanical performance, making them a versatile material choice.
Product Overview
Thin aluminum strips are typically defined as flat rolled aluminum products with thicknesses generally below 1.0 mm and widths varying according to application requirements. These strips are produced through advanced cold rolling and annealing processes to offer outstanding dimensional accuracy and surface quality. The flexibility, conductivity, and strength of these strips position them as essential components in modern engineering and manufacturing.

Features
1. Lightweight and High Strength
Thin aluminum strips maintain aluminum's fundamental advantage — an strength-to-weight ratio making them ideal for applications where weight savings is critical without compromising mechanical performance.
2. Superior Corrosion Resistance
The aluminum oxide film prevents oxidation even at sub-micron thickness; incorporating alloys like 5xxx enhance marine and chemical resistance.
3. Outstanding Formability and Workability
Cold-rolled thin strips can be bent, shaped, or stamped with minimal cracking, opening dozens of manufacturing and assembly scenarios.
4. Excellent Surface Finish and Consistency
Advanced rolling technology and surface treatments produce bright, uniform finishes perfect for decorative as well as functional applications.
5. Electrical and Thermal Conductivity
Certain thin aluminum strips (notably 1xxx alloy series) deliver good electrical and heat conduction, which benefits electronic sector applications.
