5 series aluminum alloys are representative of aluminum-magnesium alloys (Al-Mg series). They use magnesium as the primary alloying element (typically 2.5%-5%), with small amounts of manganese, chromium, and other elements added to optimize performance. Their core advantages of 5 series aluminum lie in the high strength, corrosion resistance, and lightweight design. They can be further strengthened through cold working (such.. read more →
