However, the price of various elements is inconsistent, and the lack of precious metal content is a major cause of poor profile quality. Only in strict proportion then can produce aluminum extrusions of excellent quality. The prepared raw materials are placed in an aluminum melting furnace to be melted, slag is discharged, cooled, and then cast aluminum ingots or bars are used for the production of aluminium profiles. If the exhaust is not ideal, the air bubbles in the aluminium profile will cause defects. The aluminium profiles for doors and windows are mainly made of 6063 grade aluminum alloy. If the aluminum extrusion manufacturer uses the national standard 6063 aluminum ingot, it will be guaranteed in terms of raw material quality.
