6061 Aluminum Sheet

6061 aluminum sheet is an Al-Mg-Si series heat-treatable aluminum alloy (national standard GB/T 3190), containing 1.0% Mg, 0.6% Si and 0.28% Cu, T6 state tensile strength ≥310MPa, hardness HV ≥95. It has **excellent comprehensive performance**: good corrosion resistance, weldability and processability (bending/stamping), and the surface can be anodized to enhance wear resistance. It is widely used in aerospace structural parts, automobile bodies, mechanical parts and building curtain walls, and is a benchmark material for industrial-grade high-strength aluminum alloys.

6061 aluminum sheet has the following core characteristics:

1. Comprehensive performance balance: After T6 heat treatment, the strength (310MPa) and ductility (δ≥12%) are balanced, which is better than most aluminum alloys;

2. Stress corrosion resistance: Mg2Si strengthening phase structure gives excellent resistance to stress corrosion cracking;

3. Low temperature toughness: -196℃ impact toughness still remains above 80%, suitable for low temperature equipment;

4. Anodizing adaptability: The oxide film has strong bonding strength and can achieve hard oxidation of more than 20μm (HV≥800);

5. Welding has no crack tendency: When matching 4043 welding wire, the weld strength coefficient reaches 0.9.

(Compared with 2 series/7 series aluminum: achieve the best balance between strength, corrosion resistance and cost)

Five-level protection standards are implemented:

Standard status:
