Manufacturing Process of 1100 Aluminum Coil
Pregatirea materiei prime
Pure aluminum ingots are melted and cast into billets, which are then hot-rolled into coils. The process ensures a uniform and high-quality product.
Cold Rolling & Annealing
The hot-rolled coils are further cold-rolled to achieve desired thickness, followed by annealing to restore ductility and improve surface finish.
Tratamente de suprafață
Surface treatments such as polishing, anodizing, or coating may be applied depending on application requirements.
Controlul calității
Rigorous testing ensures the alloy’s composition, mechanical properties, surface quality, and dimensional accuracy meet industry standards.
