*Part name: Extruded aluminum profile
*Material: GB-6063-T5 (AL -6063-T5) aluminum alloy
- 6063 aluminum alloy chemical ingredients: Cu 0.1%, Si 0.2%-0.6%，Fe 0.4%，Mn 0.1%，Mg 0.45%-0.9%，Zn 0.1%，Cr 0.1%；Ti 0.1%，Al 97.6%-98.45%
- T5 hot treatment method, higher tensile strength and hardness, more stable mechanical properties
6063-T5,this grade is often used, price is moderate, the oxidation effect is also acceptable.
*Surface treatment: common anodized blue color, 5~8µ thickness
16 countersunk holes, 45° chamfer at each end
1.5 meters length extruded aluminum profile
*Application: attached into small boat hull (pilot project)
*Manufacture process: Material extrusion - Cutting - Anodizing blue - inspection for packing
