### **Product Datasheet: 2214 Aluminum Alloy** --- #### **1. Overview** 2214 Aluminum Alloy is a high-strength aluminum-copper-magnesium-silicon alloy designed primarily for forging applications requiring excellent combination of strength, toughness, and good machinability. As a variant of the 2014 alloy with modified composition, 2214 offers improved mechanical properties and enhanced performance in forged components. This heat-treatable alloy is particularly suitable for applications where high strength-to-weight ratio and reliability under dynamic loading conditions are critical requirements. --- #### **2.
