What Is Anodizing Cast Aluminum In precision casting, including die casting , sand casting , and gravity casting , the process typically involves melting aluminum alloy, injecting or pouring it into a mold, and then allowing it to cool. Certain metal elements are added to the aluminum alloys to ensure precise casting and enhance flow properties. However, it's important to note that adding these elements, such as silicon, makes the resulting alloys unsuitable for anodizing . Commonly utilized die-cast aluminum alloys, like Aluminum 360 , Aluminum 383 (ADC12) , Aluminum A356 , Aluminum A380 , and Aluminum B390 , are chosen for their casting suitability. These alloys exhibit favorable characteristics for the precision casting process, but the presence of alloying elements makes them unsuitable for anodization. On the other hand, anodized aluminum alloy is tailored explicitly for parts requiring surface anodization. This specialized aluminum alloy is carefully formulated to achieve v
