Alclad 2014-O Aluminum alloy,Aluminum 2014-O alloy,E FORU

### **Alclad 2014-O Aluminum Alloy Product Introduction** **1. Overview** Alclad 2014-O is a specialized version of the 2014 aluminum alloy in the annealed (O) temper, featuring a protective aluminum coating on both surfaces. The "Alclad" designation indicates that the material consists of a high-strength 2014 aluminum core metallurgically bonded with a thin layer of high-purity aluminum or aluminum alloy. This construction provides the excellent strength characteristics of 2014 aluminum combined with superior corrosion resistance, making it ideal for applications where both mechanical performance and environmental durability are required. **2. Chemical Composition (Typical, % by Weight)** The core material maintains standard 2014 aluminum composition while the cladding is high-purity aluminum. | Element | Core (2014) | Cladding | |---------|-------------|----------| | **Aluminum (Al)** | Balance | ≥99.0% | | **Copper (Cu)** | 3.9-5.0 | ≤0.10 | | **Silicon (Si)** | 0.50-1.2 | ≤0.20 | | **Magnesium (Mg)** | 0.20-0.8 | ≤0.10 | | **Manganese (Mn)** | 0.40-1.2 | ≤0.10 | | **Iron (Fe)** | ≤0.20 | ≤0.40 | | **Zinc (Zn)** | ≤0.10 | ≤0.10 | *Note: The high-purity aluminum cladding provides sacrificial corrosion protection while the core delivers mechanical strength.* **3. Physical Properties** | Property | Value | |----------|-------| | **Density** | 2.80 g/cm³ | | **Melting Point** | 510-638°C | | **Electrical Conductivity** | 47% IACS | | **Thermal Conductivity** | 155 W/(m·K) | | **Coefficient of Thermal Expansion** | 23.0 × 10⁻⁶/K (20-100°C) | | **Modulus of Elasticity** | 73 GPa | **4. Mechanical Properties (Typical for O Temper)** The O temper provides maximum formability with basic mechanical properties. | Property | Value | |----------|-------| | **Tensile Strength** | 240-280 MPa | | **Yield Strength (0.2% Offset)** | 130-160 MPa | | **Elongation (% in 50mm)** | 14-18% | | **Hardness (Brinell)** | 65-75 HB | | **Shear Strength** | 170-200 MPa | *Key Characteristics of O Temper:* * **Maximum Formability**: Excellent for severe forming and bending operations * **Good Corrosion Resistance**: Superior protection from aluminum cladding * **Sacrificial Protection**: Cladding protects core material galvanically * **Good Weldability**: Suitable for various welding processes **5. Product Applications** Alclad 2014-O is primarily used in applications requiring formability combined with future strength potential and corrosion resistance. * **Aerospace Components**: Aircraft skin panels, structural parts requiring forming * **Marine Applications**: Boat components and marine hardware * **Transportation**: Vehicle body panels and structural components * **Architectural**: Decorative and structural building elements * **Chemical Equipment**: Tanks and vessels for chemical processing * **Heat Exchangers**: Components requiring corrosion protection * **Precision Parts**: Components requiring severe forming before heat treatment **6. International Standards** Alclad 2014-O is recognized under major international standardization systems. | Standard System | Designation | |-----------------|-------------| | **EN (Europe)** | EN AW-2014A Alclad O | | **ISO** | AlCu4SiMg Alclad O | | **ASTM (USA)** | ASTM B209 2014 Alclad O | | **UNS (USA)** | UNS A92014 Alclad O | | **JIS (Japan)** | A2014 Alclad O | | **GB (China)** | 2A14 Alclad O | --- **Summary** **Alclad 2014-O Aluminum Alloy** represents a **unique material combination** that provides **exceptional formability in the annealed condition with built-in corrosion protection**. The Alclad construction offers the perfect solution for applications requiring severe forming operations followed by heat treatment to develop high strength, while maintaining excellent resistance to corrosive environments. The high-purity aluminum cladding acts as a sacrificial layer, protecting the high-strength 2014 core material from corrosion, making it particularly valuable for aerospace components, marine applications, and structural elements exposed to harsh environments. This material combination allows manufacturers to perform demanding forming operations in the soft O temper condition and subsequently heat-treat the components to achieve the high strength characteristics of 2014-T6 temper, all while maintaining superior corrosion resistance through the protective cladding.
