1201 Alloy,hot rolled sheet，E FORU

### **Product Datasheet: 1201 Aluminum Alloy, Hot Rolled Sheet** **1. General Overview** 1201 Aluminum Alloy is a commercially pure aluminum alloy (≥99.00% Al) known for its excellent electrical conductivity, outstanding corrosion resistance, and very high formability. When supplied as a hot-rolled sheet, it offers a great combination of these inherent properties with good structural integrity from the hot-working process. It is one of the most widely used alloys for electrical and general engineering applications where high conductivity is the primary requirement. **2. International Standards** The 1201 alloy is recognized under several key international standards, ensuring global consistency. * **ISO:** Al99.0 (ISO 209) * **ASTM:** ASTM B209 (Standard Specification for Aluminum and Aluminum-Alloy Sheet and Plate) * **AA:** AA 1201 (Aluminum Association designation) * **EN (European Standard):** EN AW-1200 [Al99.0] * **UNS:** UNS A91201 * **JIS:** A 1200 (JIS H 4000) **3. Chemical Composition (Weight %)** The composition is characterized by a very high aluminum content and strict limits on impurities, particularly iron and silicon, to maximize electrical conductivity. | Element | Content (%) | | :--- | :--- | | **Aluminum (Al)** | ≥ 99.00 (Balance) | | **Iron (Fe)** | ≤ 0.70 | | **Silicon (Si)** | ≤ 0.50 | | **Copper (Cu)** | ≤ 0.10 | | **Zinc (Zn)** | ≤ 0.10 | | **Manganese (Mn)** | ≤ 0.10 | | **Other Elements** | ≤ 0.15 each; ≤ 0.05 total | *Note: The low levels of alloying elements, especially the (Fe+Si) content, are critical for achieving high electrical conductivity.* **4. Physical Properties** The physical properties are typical of commercially pure aluminum, with high conductivity being a standout feature. | Property | Value / Description | | :--- | :--- | | **Density** | 2.71 g/cm³ (0.098 lb/in³) | | **Melting Range** | ~ 655 °C (1211 °F) | | **Coefficient of Thermal Expansion (20-100°C)** | 23.6 x 10⁻⁶/°C | | **Thermal Conductivity** | ~ 222 W/m·K (57% of Copper IACS) | | **Electrical Conductivity** | ~ 59-62% IACS (International Annealed Copper Standard) | | **Modulus of Elasticity** | 70 GPa (10.2 x 10⁶ psi) | **5. Mechanical Properties (Typical for Hot Rolled Sheet, H14 Temper Common)** While often supplied in the "as-hot-rolled" condition (which can resemble an H14 temper), properties can vary with the final rolling reduction and thermal history. The H14 temper (work hardened and partially annealed) is a common specification for sheet products. | Property | Typical Value (H14 Temper) | | :--- | :--- | | **Tensile Strength** | 110 - 145 MPa (16,000 - 21,000 psi) | | **Yield Strength (0.2% Offset)** | 95 - 120 MPa (14,000 - 17,500 psi) | | **Elongation at Break** | 10 - 20 % (in 50 mm / 2 inches) | | **Hardness, Brinell** | ~ 35 HB | *Note: For the "O" (Annealed) temper, tensile strength is typically 85-115 MPa with elongation over 25%.* **6. Key Characteristics & Advantages** * **Excellent Electrical Conductivity:** Its primary advantage, making it the alloy of choice for electrical busbars, conductors, and rotor windings. * **Superior Corrosion Resistance:** The high purity gives it excellent resistance to atmospheric corrosion, similar to pure aluminum. * **High Formability:** It can be easily bent, stamped, and formed into complex shapes, especially in the annealed (O) condition. * **Good Weldability:** It can be readily welded using common methods like TIG, MIG, and resistance welding. * **High Thermal Conductivity:** Suitable for heat exchanger applications and heat sinks. * **Non-magnetic and Non-sparking:** Ideal for applications in sensitive electronic or hazardous environments. **7. Product Applications** 1201 Hot Rolled Sheet is utilized in a wide range of industries where its conductive and corrosive properties are critical. * **Electrical Engineering:** * Busbars and electrical connectors * Transformer windings and coils * Electrical enclosures and housings * **Heat Exchangers:** * Fin stock for air conditioning and refrigeration * **General Engineering & Architecture:** * Chemical equipment linings and tanks * Sheet metal work, nameplates, and decorative parts * Reflectors for light and heat * **Food and Chemical Processing:** * Equipment and piping due to its non-toxic nature and corrosion resistance. **8. Available Forms & Processing** * **Primary Form:** Hot Rolled Sheet / Coil. * **Common Tempers:** O (Annealed), H14, H16, H18. * **Fabrication:** Excellent for deep drawing, spinning, and bending. It can be brazed and soldered with standard techniques. --- **Disclaimer:** The information provided is typical and intended for reference purposes.
