You\u2019ll find them in aerospace and military applications. They do sacrifice some corrosion resistance though.<\/li>\n\n\n\n<li><strong>3xxx Series:<\/strong>\u00a0Alloyed with manganese, these have good formability and moderate strength. You often see them in roofing, siding, and cooking utensils due to their corrosion resistance.<\/li>\n\n\n\n<li><strong>4xxx Series:<\/strong>\u00a0Silicon is the major addition, improving wear resistance and lowering thermal expansion. These alloys are common for engine parts, automotive applications, and welding wire.<\/li>\n\n\n\n<li><strong>5xxx Series:<\/strong>\u00a0Magnesium drives strength and boosts corrosion resistance, especially in marine environments. Widely used for shipbuilding, automotive parts, and pressure vessels.<\/li>\n\n\n\n<li><strong>6xxx Series:<\/strong>\u00a0Balanced alloys with magnesium and silicon. Great corrosion resistance, good strength, and excellent machinability make them a top choice in structural applications, like bridges and building frames.<\/li>\n\n\n\n<li><strong>7xxx Series:<\/strong>\u00a0Zinc is the key for ultra-high strength, often paired with magnesium and copper. Aerospace and sports equipment rely heavily on this series, but they can be less corrosion resistant.<\/li>\n\n\n\n<li><strong>8xxx Series:<\/strong>\u00a0A catch-all group with various elements like iron and lithium for niche uses, including foil, packaging, and electrical conductors.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Cast Aluminum Alloys Overview<\/h3>\n\n\n\n<p>Unlike wrought alloys, cast aluminum alloys are designed for foundry use.
