Hemaokang Steel (Shandong) Co., Ltd. proudly presents our premium 2011 Aluminum Rod 3/4 Inch Diameter Free Cutting Alloy, specifically engineered for high-speed CNC lathe machining. With an annual export value exceeding US$50 million and a dedicated team of 51–100 professionals, we guarantee consistent quality and reliable supply for global buyers. This free-cutting alloy offers exceptional machinability, tight tolerances, and a smooth surface finish, making it the ideal choice for intricate automotive components, electronic connectors, and precision fittings. Backed by our ISO 9001 certification, every rod is produced under strict quality control to ensure dimensional accuracy and material consistency.
Our 2011 aluminum rod is designed to maximize productivity and reduce tool wear in your CNC lathe operations. The 3/4 inch diameter is a standard size that fits common collets and chucks, while the free-cutting property allows for chip breaking and excellent surface finish without secondary operations. Whether you need bars in custom lengths, specific tempers, or special packaging, we offer flexible solutions to meet your production requirements.

Benefits for Your CNC Lathe Operations: By choosing our 2011 aluminum rod, you can significantly reduce cycle time and tooling costs. The free-cutting property minimizes built-up edge and allows for higher cutting speeds (up to 300 m/min) without compromising surface quality. The material also produces short, broken chips that are easy to evacuate, reducing downtime for chip clearing. Additionally, the consistent diameter tolerance ensures that your parts meet tight specifications every time, reducing scrap rates and improving overall yield.
Trusted by Global Markets: Hemaokang Steel exports to North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East, with annual export value between US$50 million and US$100 million. Our facility in Liaocheng, Shandong, operates with advanced extrusion and finishing lines, and every batch is tested for chemical composition and mechanical properties. We ship from Qingdao port, ensuring fast and reliable logistics worldwide.

Frequently Asked Questions
-
Q: What is the typical diameter tolerance for your 3/4 inch aluminum rod?
A: Our standard tolerance is ±0.05 mm (0.002 inch). Tighter tolerances (±0.025 mm) are available upon request for precision applications. -
Q: Can you supply rods in custom lengths other than 3m or 6m?
A: Yes, we can cut to any length between 500 mm and 6000 mm as per your order. Please specify your required length and tolerance when placing an order. -
Q: Is anodizing or other surface treatment available?
A: Yes, we offer optional anodizing (clear, black, or color), as well as polishing and brushing. Contact our sales team for details and pricing. -
Q: What temperature range is suitable for this alloy?
A: The 2011 alloy performs well in temperatures from -40°C to +150°C. For higher temperature applications, consider other heat-treatable alloys. -
Q: Do you provide a material test certificate (MTC) with each shipment?
A: Absolutely. Every shipment includes an ISO 9001 compliant MTC showing chemical composition, mechanical properties, and traceability. -
Q: What is the typical lead time for a standard order?
A: For standard diameters and lengths, lead time is 10–15 working days after deposit. Custom orders may require 20–25 working days depending on volume and specifications. -
Q: Can I get a free sample before placing a bulk order?
A: Yes, we offer free samples (200 mm length) for evaluation. Shipping cost is borne by the buyer. Please contact our sales representative to arrange. -
Q: How do you pack the rods to avoid damage during transit?
A: Rods are bundled with plastic straps, wrapped in water-resistant paper, and packed in wooden crates or steel-frame bundles for export. Each bundle is clearly labeled with weight, size, and heat number.
