Frequently Asked Questions
-
Q: What does “free-cutting grade” mean for 2011 aluminum?
A: It means the alloy contains lead and bismuth to improve machinability – chips break easily, reducing machine downtime and improving surface finish. -
Q: Can you supply diameters smaller than 3mm or larger than 100mm?
A: Our standard range is 3–100mm. For special sizes outside this range, please contact us; we may be able to arrange custom production. -
Q: What is the typical anodized layer thickness? Is it uniform?
A: Standard thickness is 5–15 microns, applied uniformly. For enhanced durability, we can increase thickness up to 25 microns upon request. -
Q: What temper options are available?
A: We commonly supply T3, T4, and T6 tempers. The choice depends on your required hardness and ductility. Let us know your application, and we will recommend the best option. -
Q: Do you offer cut-to-length services or only standard 3000mm bars?
A: Yes, we can cut to any length you need. Please specify the required length when placing your order. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is 500 kg for standard sizes. For smaller trial orders, please inquire – we often accommodate samples or small batches. -
Q: How is the product packaged for export?
A: Bars are packed in wooden crates or steel-bundled with protective wrapping to prevent scratches and corrosion during transit. -
Q: Do you provide material certificates or third-party inspection?
A: Yes, we provide mill test certificates with each shipment. Third-party inspection (e.g., SGS, Intertek) is also available at an additional cost.
