### **5150 Aluminum Alloy Product Introduction** **Overview** 5150 Aluminum Alloy is a non-heat-treatable alloy belonging to the Al-Mg series (5xxx series). It is characterized by its **medium to high strength**, excellent corrosion resistance, and good formability and weldability. The alloy derives its strength primarily from its magnesium (Mg) content, which is achieved through strain hardening (H temper). 5150 offers a reliable balance of strength, durability, and workability, making it a versatile choice for various structural and general engineering applications. --- ### **1. Chemical Composition** The chemical composition of 5150 Aluminum Alloy is the foundation of its properties. The following table outlines the typical elemental composition by weight percentage (%). | Element | Content (%) | | :--- | :--- | | **Aluminum (Al)** | Balance | | **Magnesium (Mg)** | 3.5 - 4.5 | | **Silicon (Si)** | ≤ 0.30 | | **Iron (Fe)** | ≤ 0.50 | | **Copper (Cu)** | ≤ 0.10 | | **Manganese (Mn)** | 0.10 - 0.30 | | **Chromium (Cr)** | 0.05 - 0.25 | | **Zinc (Zn)** | ≤ 0.20 | | **Titanium (Ti)** | ≤ 0.10 | | **Others (Each)** | ≤ 0.05 | | **Others (Total)** | ≤ 0.15 | *Note: The Magnesium content provides solid solution strengthening, while Manganese and Chromium help control the grain structure and improve strength.* --- ### **2.
