3003 Brushed Aluminum Sheet
The 3003 brushed aluminum sheet is made from Al-Mn alloy (1.0-1.5% manganese), with parallel textures formed by mechanical brushing, combining metallic luster and matte finish.It offers 20% higher strength than pure aluminum (e.g., 1050) while maintaining decorative appeal and processing flexibility, widely used in construction, home appliances, transportation, etc.

Overview
The 3003 brushed aluminum sheet is an AL-Mn series corrosion-resistant aluminum alloy, with manganese (Mn 1.0-1.5%) as the primary alloying element. It cannot be strengthened by heat treatment but can be enhanced through cold working. Its surface is treated with a brushing process to create fine linear textures, combining metallic aesthetics with corrosion resistance. It is widely used in applications requiring high corrosion resistance, formability, and weldability.
Feature
1.Balanced Strength & Lightweight: Tensile strength 140-180MPa, 1/3 the weight of steel, ideal for scenarios requiring both load-bearing and weight reduction.
2.Corrosion & Weather Resistance: Manganese enhances oxide film stability, with better corrosion resistance than pure aluminum in humid/mildly acidic environments, longer outdoor service life.
3.Brushed Texture Functionality: Lines reduce light reflection (≤60%), minimize glare, and create micro anti-slip structures for improved grip and wear resistance.
4.Processing Compatibility: Supports anodizing, painting, stamping, etc., forming complex curves for customized designs.
Application
1.Construction: High-rise curtain wall trims, ceiling designs, elevator cabin panels.
2.Transportation: Automotive interior panels (e.g., door trims), high-speed rail decorative parts.
3.Industrial Equipment: Chemical equipment shields, motor casings.
4.Home Appliances & Electronics: Refrigerator panels, laptop casings, speaker grilles.
5.Outdoor Infrastructure: Urban signages, bus stop canopies.
