### **Product Datasheet: 2036-T4 Aluminum Alloy** **1. Overview** 2036-T4 Aluminum Alloy is a high-strength, heat-treatable aluminum-copper-magnesium alloy. It is primarily valued for its excellent combination of strength and formability in the T4 temper (solution heat-treated and naturally aged). This makes it a preferred material for applications requiring complex shapes and good mechanical properties, most notably in the automotive industry for body panels and structural components. **2. International Standards** 2036-T4 Aluminum alloy is recognized under several major international standards systems: * **UNS:** UNS A92036 * **ASTM:** ASTM B209 (Standard Specification for Aluminum and Aluminum-Alloy Sheet and Plate) * **SAE:** SAE J454 (Recommended Practice for Chemical Compositions of Wrought Aluminum Alloys) * **AA (Aluminum Association):** AA 2036 (The defining standard for composition and temper) *Note: While common in North America, it may be supplied as equivalents under other national standards (e.g., EN, JIS) based on customer requirements.* **3. Chemical Composition (Weight %)** The composition conforms to the limits set by the Aluminum Association (AA). | Element | Content (%) | | :--- | :--- | | **Aluminum (Al)** | Balance | | **Copper (Cu)** | 2.2 - 3.0 | | **Magnesium (Mg)** | 0.30 - 0.6 | | **Manganese (Mn)** | 0.10 - 0.40 | | **Iron (Fe)** | ≤ 0.50 | | **Silicon (Si)** | ≤ 0.50 | | **Zinc (Zn)** | ≤ 0.25 | | **Chromium (Cr)** | ≤ 0.10 | | **Others (Each)** | ≤ 0.05 | | **Others (Total)** | ≤ 0.15 | **4. Physical Properties** | Property | Value / Description | | :--- | :--- | | **Density** | 2.78 g/cm³ (0.100 lb/in³) | | **Melting Range** | ~ 555 - 650 °C (1030 - 1200 °F) | | **Electrical Conductivity** | Approximately 40-45% IACS (International Annealed Copper Standard) | | **Thermal Conductivity** | ~ 130 - 150 W/m·K | | **Coefficient of Thermal Expansion** | ~ 23.4 x 10⁻⁶/°C (20-100°C) | **5. Mechanical Properties (Typical for T4 Temper)** Properties are typical for sheet material and may vary with section size and processing history. | Property | Value | | :--- | :--- | | **Tensile Strength (Ultimate)** | 345 - 380 MPa (50 - 55 ksi) | | **Tensile Yield Strength (0.2% Offset)** | 170 - 220 MPa (25 - 32 ksi) | | **Elongation at Break (in 50mm)** | 24 - 28% | | **Modulus of Elasticity (Elastic Modulus)** | 71.0 GPa (10,300 ksi) | | **Shear Modulus** | 27.0 GPa (3,920 ksi) | | **Poisson's Ratio** | 0.33 | | **Fatigue Strength** | 125 MPa (18 ksi) (For 500 million cycles, R.R. Moore test) | | **Brinell Hardness (HB)** | ~ 85 | **6. Key Characteristics & Advantages** * **High Formability:** The T4 temper provides excellent ductility, allowing it to be deep-drawn, stretch-formed, and bent into complex shapes without cracking. * **Good Strength-to-Weight Ratio:** Offers substantial strength while being lightweight, contributing to fuel efficiency in automotive applications. * **Age-Hardenable:** After forming, components can be artificially aged (e.g., to a T6 temper) to achieve higher strength. * **Good Machinability:** Can be readily machined in the T4 temper. * **Typical Surface Finish:** Can be supplied with a mill finish, or further anodized, painted, or coated for enhanced corrosion resistance and aesthetics. **7. Product Applications** 2036-T4 is predominantly used in the transportation sector, but its properties make it suitable for various structural applications. * **Automotive Industry (Primary Application):** * Body-in-White (BIW) components * Inner and outer body panels (hoods, doors, fenders) * Seat frames and structural reinforcements * Bumper reinforcements * **General Manufacturing:** * Chassis and enclosures for machinery * Various structural components requiring a blend of formability and strength **8.
