Product Description

Precision 6061-T6 Aluminum Square Tube 30×30×2.0mm
Certified to ASTM B221/EN 573-3 standards, our 30×30×2.0mm aluminum square tube delivers 310MPa tensile strength and 276MPa yield strength at 2.7g/cm³ density - achieving 60% weight reduction versus steel equivalents. The T6 heat-treated 6061 alloy features optimized Mg (0.8-1.2%) and Si (0.4-0.8%) composition, forming Mg₂Si precipitates that ensure structural stability across -50°C to 150°C operating temperatures.

Engineered for Demanding Environments
With 10-15 Webster hardness and ≥8% elongation, this profile withstands high-impact scenarios while maintaining machining flexibility. The chromium-enhanced formula (Cr 0.04-0.35%) passes 168-hour salt spray tests (ASTM B117), making it ideal for coastal installations and high-humidity industrial applications. Precision-extruded walls (2.0mm±0.1mm) ensure uniform stress distribution in load-bearing frameworks.

Analysis of Technical Advantages

1. Gold alloy formula (chemical composition)

Magnesium (Mg) and silicon (Si): form a strengthening phase Mg ₂ Si, endowing high strength and thermal stability.

Chromium (Cr): enhances stress corrosion resistance and extends outdoor service life.

Low impurity control: Iron (Fe) ≤ 0.7%, copper (Cu) ≤ 0.4%, ensuring homogeneity and defect free.

 

2. Hardcore performance data (T6 state)

Tensile strength: ≥ 310 MPa (equivalent to 70% of 45 # steel, with only one-third of its weight)

Yield strength: ≥ 276 MPa (strong deformation resistance and more stable support structure)

Elongation rate: ≥ 8% (moderate toughness, avoiding brittle fracture)

Hardness: 95 HB (wear-resistant and scratch resistant, suitable for frequent assembly scenarios)

 

3. Environmental adaptability

Temperature range:- Stable performance from 50 ° C to 150 ° C, with no risk of low-temperature embrittlement.

Corrosion resistance level: Passed the 168 hour neutral salt spray test (ASTM B117), suitable for coastal/high humidity areas
