7075 offers superior mechanical strength but at higher cost xem bong da truc tiep with more demanding machining requirements, while 6061 provides a balanced performance-to-cost ratio.

Machinability xem bong da truc tiep Post-Processing Compatibility

6061 machines smoothly with lower cutting forces, suitable for high-speed, high-feed CNC environments. 7075's higher hardness requires rigid machines xem bong da truc tiep wear-resistant tooling, with slightly lower overall efficiency.

6061 causes less tool wear xem bong da truc tiep easily achieves Ra ≤ 1.6 μm surface roughness. 7075's short chips aid chip evacuation xem bong da truc tiep can achieve fine finishes with optimized parameters, though tool wear is faster.

For anodizing, 6061 produces a uniform decorative or structural oxide layer. 7075's higher copper content can cause discoloration or spots, making it better suited for hard anodizing to improve corrosion xem bong da truc tiep wear resistance.

In welding, 6061 is compatible with TIG xem bong da truc tiep MIG processes, suitable for frames xem bong da truc tiep enclosures. 7075 has poor weldability xem bong da truc tiep is generally avoided for load-bearing welded structures.
