Free-Cutting Aluminum Alloy Supplier--6262 Aluminum Bar, Rod, and Tube
6262 aluminum alloy is a free-machining aluminum material from the 6xxx series (Al-Mg-Si), specifically developed for high-speed CNC machining and precision components.
It contains trace amounts of bismuth (Bi) and lead (Pb), which significantly improve chip breaking and machining efficiency while maintaining good corrosion resistance—making it a balanced alternative to 2011 aluminum.
6262 Aluminum Chemical Composition
| Element | Content (%) |
|---|---|
| Aluminum (Al) | Balance |
| Magnesium (Mg) | 0.8 – 1.2 |
| Silicon (Si) | 0.4 – 0.8 |
| Bismuth (Bi) | 0.4 – 0.7 |
| Lead (Pb) | 0.4 – 0.7 |
| Iron (Fe) | ≤ 0.7 |
| Copper (Cu) | ≤ 0.15 |
| Zinc (Zn) | ≤ 0.25 |
| Others | ≤ 0.15 |
6262 Aluminum Temper Options
6262 aluminum is available in multiple tempers to meet different machining and strength requirements:
T6 – Solution heat-treated and artificially aged
→ Standard temper for general CNC machiningT651 – T6 + stress relieved by stretching
→ Improved dimensional stability, reduced distortionT9 – Solution heat-treated, cold worked, and artificially aged
→ Higher strength with improved machining performance
