2011-T3 Free Cutting Round Aluminum Bar for CNC Automatic Lathe Precision Turning Components

The 2011-T3 round aluminum bar is specifically engineered for high-speed machining applications. Its copper-lead alloy composition provides outstanding chip-breaking characteristics and excellent surface finish quality. This free-cutting alloy is the preferred choice for CNC automatic lathe turning, screw machine operations, and high-volume precision component manufacturing where productivity and dimensional accuracy are critical.

• Copper-lead alloy with superior free-cutting machinability
• T3 temper (solution heat treated, cold worked, and naturally aged)
• Excellent chip formation for uninterrupted high-speed machining
• Produces smooth surface finishes with minimal tool wear
• Conforms to ASTM B221, EN 573-3, and GB/T 3191 standards

• CNC automatic lathe turned components
• Precision screws, bolts, and threaded fittings
• High-volume screw machine products
• Electronic connector and terminal parts
• Automotive sensor and valve components

All bars are coated with anti-rust oil and wrapped in waterproof kraft paper, then packed in fumigation-free plywood cases. Standard delivery within 5 working days for stock sizes, 15-25 days for custom production orders.
