Aluminum scrap

Raw aluminum Raw aluminum, also known as stir-fried aluminum in the Chinese industry, is a low-purity aluminum extracted from a naturally refined chemical component, aluminum oxide. Raw aluminum is impure aluminum, and like pig iron, it will break if you hit it hard. Aluminum with a composition below 98% is brittle and hard, and can only be used for sand casting.   Die-cast aluminum Aluminum suitable for die casting is die-cast aluminum, usually die-cast aluminum alloy. Through the die-casting process, the aluminum alloy is melted and injected into the mold, and then quickly cooled to form an aluminum alloy product.
