The so-called aluminum alloy generally refers to aluminum containing some other chemical elements, such as common aluminum-silicon alloy, aluminum-magnesium alloy and so on. ADC- 12 is an aluminum-silicon alloy.

Generally speaking, AOO aluminum ingots are equivalent to raw materials, and ADC- 12 can be made by adding silicon and copper.

AOO ingot is electrolyzed from aluminum ore, and ADC- 12 is synthesized from aluminum and other elements. Of course, in actual production, it is generally smelted from waste aluminum.

AOO is the raw material for manufacturing all other aluminum alloys, while ADC- 12 is the raw material for casting automobile die parts. Because it contains copper, magnesium and other elements that are more expensive than aluminum, its value is naturally high, and of course, because of its use, its price is arbitrarily higher.

ADC- 12 and other aluminum alloys belong to cast aluminum, and broken doors and windows belong to deformed aluminum, which are two categories of aluminum alloys. Deformed aluminum is also an aluminum alloy, but it is commonly called cooked aluminum because of its high aluminum content. The composition is close to pure aluminum, but it also contains trace amounts of other elements. The brand of door and window materials is generally 6 series aluminum, and the more common one is 6063.

As long as it is produced by a regular manufacturer, it is generally up to standard. Specifically, chemical inspection and physical inspection should be done.
