Aluminum Bar Machining Tips: T6 6061/6063 Bending & Cutting
Machining aluminum bars, particularly T6 6061 and 6063 alloys, requires a nuanced understanding of material properties and specialized techniques. These alloys are widely used in aerospace, automotive, and architectural applications due to their excellent strength-to-weight ratio and corrosion resistance. When machining aluminum bars, precision is paramount to maintain the material's integrity while achieving desired tolerances.
The T6 temper of 6061 and 6063 aluminum indicates that it has been solution heat-treated and artificially aged, resulting in increased strength. However, this also makes the material more prone to stress cracking during machining. At Baobin Steel, with over 30 years of experience in metals manufacturing, we understand these challenges intimately. Our advanced facilities ensure that every aluminum bar meets the highest industry standards for consistency and workability.
When bending aluminum bars, several factors must be considered. The bend radius should be at least 3 times the material thickness to prevent cracking. For T6 6061, which has a tensile strength of approximately 45,000 PSI, cold working techniques must be employed carefully. Our engineers recommend using specialized tooling and maintaining proper lubrication to minimize friction and heat generation. This is particularly important when working with Baobin's premium aluminum bars, which achieve a 98% customer satisfaction rate through our strict quality control processes.
Cutting operations require equally specialized approaches. Band sawing with carbide-tipped blades or circular saws with generous tooth gullets are preferred methods. The cutting speed should be optimized for the specific alloy—typically between 500-1000 SFPM for 6061/6063. Since Baobin Steel supplies aluminum bars to over 100 countries, we ensure our products maintain precise dimensional tolerances that facilitate superior machinability across various global manufacturing standards.
Tool selection is critical when machining these alloys. High-speed steel (HSS) or carbide tools with positive rake angles work best. The coolant should be applied generously to prevent built-up edge formation, which can compromise surface finish.

Post-machining treatments may be necessary depending on application requirements. Stress relief annealing can help minimize residual stresses, especially when components undergo further bending or forming operations. Baobin Steel's extensive product range includes heat-treatable aluminum alloys that maintain precise mechanical properties even after secondary operations, making us a preferred supplier for manufacturers requiring precision aluminum components.
Quality verification should include non-destructive testing methods to detect any surface imperfections or subsurface defects that might compromise structural integrity. Our advanced manufacturing facilities in Shanghai incorporate automated inspection systems that verify every batch against international standards, ensuring our 50,000+ annual ton capacity maintains consistent quality across all product lines.
