Is pure aluminum not the raw material? Why are pure aluminum rods hollow? Time consuming and exhausting. Who can introduce?!!! Thank you！！ (the country has banned the export tax refund of pure aluminum products). Why is the product still exported to Korea and Japan?.
As to why pure aluminum rods are made of hollow, this is an industrial consideration, and I do not know......
Aluminum smelting needs to consume a great deal of energy (three aluminium oxide two) in electrolytic molten state, while pure aluminum is mainly used as industrial raw material for export, with low added value, so the country does not encourage export.
