1035 Aluminum alloy,Aluminum 1035 alloy,E FORU

### **1035 Aluminum Alloy Product Introduction** **1. Overview** 1035 aluminum alloy is a commercially pure aluminum grade belonging to the 1xxx series. It is characterized by its excellent electrical and thermal conductivity, high corrosion resistance, good workability, and low strength. As a non-heat-treatable alloy, its strength can only be enhanced through cold working (strain hardening). It is one of the most widely used aluminum alloys for applications requiring high formability, surface finish, and conductivity. **2. Chemical Composition (Typical, % by Weight)** The composition conforms to standards such as ASTM B479 and EN AW-1035. | Element | Content (%) | | :--- | :--- | | **Aluminum (Al)** | 99.35 min | | **Iron (Fe)** | 0.0 - 0.6 | | **Silicon (Si)** | 0.0 - 0.4 | | **Copper (Cu)** | 0.0 - 0.10 | | **Manganese (Mn)** | 0.0 - 0.05 | | **Zinc (Zn)** | 0.0 - 0.05 | | **Other Elements (Each)** | ≤ 0.03 | | **Other Elements (Total)** | ≤ 0.10 | *Note: The high minimum aluminum content (99.35%) is the primary reason for its superior corrosion resistance and conductivity.* **3. Physical Properties** | Property | Value / Description | | :--- | :--- | | **Density** | 2.71 g/cm³ (0.098 lb/in³) | | **Melting Point** | ~ 646 °C (~1195 °F) | | **Electrical Conductivity** | 61% IACS (International Annealed Copper Standard) | | **Thermal Conductivity** | 234 W/m·K | | **Coefficient of Thermal Expansion** | 23.2 µm/m·K (20-100°C) | | **Modulus of Elasticity** | 69 GPa (10,000 ksi) | **4. Mechanical Properties (Typical)** Mechanical properties vary significantly with temper (condition). | Temper | Tensile Strength (MPa) | Yield Strength (0.2% Offset, MPa) | Elongation (% in 50mm) | | :--- | :--- | :--- | :--- | | **O (Annealed)** | 70 - 110 | 25 - 45 | 30 - 40 | | **H14 (Work Hardened)** | 115 - 150 | 100 - 130 | 6 - 12 | | **H18 (Full Hard)** | 150 - 185 | 140 - 170 | 2 - 5 | *Key Characteristics:* * **Low Strength, High Ductility:** In the annealed (O) condition, it is very soft and malleable, ideal for deep drawing and complex forming. * **Excellent Formability:** It can be easily bent, stamped, and shaped. * **High Corrosion Resistance:** The pure aluminum surface forms a protective oxide layer, making it suitable for many environments. * **Superior Finishing:** It takes very well to anodizing, polishing, and painting. **5. Product Applications** 1035 aluminum is primarily supplied in the form of sheet, strip, and foil. Its key applications include: * **Heat Exchangers & Radiators:** Due to its excellent thermal conductivity. * **Electrical Busbars & Conductors:** Where high electrical conductivity is required. * **Decorative Trim & Nameplates:** Because of its excellent surface finish and anodizing quality. * **Packaging Foil:** For food and pharmaceutical packaging (often in thinner gauges like 1235). * **Chemical Equipment:** For lining and parts handling certain chemicals. * **Deep-Drawn & Spun Parts:** Such as light reflectors, kitchenware, and cosmetic cases. * **HVAC Ducting & Dampers.** **6. International Standards** 1035 aluminum is recognized under various international standard systems. | Standard System | Equivalent Designation | | :--- | :--- | | **ISO** | Al 99.35 (ISO 209) | | **ASTM (USA)** | ASTM B479 (Sheet/Strip/Foil), 1035 | | **EN (Europe)** | EN AW-1035 [Al99.35] | | **UNS (USA)** | UNS A91035 | | **JIS (Japan)** | A1035 | | **GB (China)** | 1035 (Similar to L4) | --- **Summary:** **1035 Aluminum Alloy** is the go-to choice for applications demanding the fundamental properties of pure aluminum: **excellent conductivity, outstanding corrosion resistance, and superior formability**. While its low mechanical strength limits its use in structural applications, it excels in electrical, thermal, decorative, and packaging industries. Its compliance with major international standards ensures its global availability and consistency.
