1050A Aluminum alloy,Aluminum 1050A alloy,E FORU

Of course. Here is a comprehensive English product introduction for 1050A Aluminum Alloy. --- ### **1050A Aluminum Alloy Product Introduction** **1. Overview** 1050A aluminum alloy is a commercially pure, non-heat-treatable aluminum grade from the 1xxx series. It is characterized by an excellent combination of properties, including very high corrosion resistance, superior electrical and thermal conductivity, excellent workability, and a high reflectivity. With a typical aluminum content of 99.5%, it offers a balance of formability and moderate strength, which can be enhanced through cold working. It is one of the most versatile and widely used aluminum alloys for general-purpose applications. **2. Chemical Composition (Typical, % by Weight)** The composition conforms to standards such as EN 573-3 and ASTM B491. | Element | Content (%) | | :--- | :--- | | **Aluminum (Al)** | **99.50 min** | | **Iron (Fe)** | 0.0 - 0.40 | | **Silicon (Si)** | 0.0 - 0.25 | | **Copper (Cu)** | 0.0 - 0.05 | | **Manganese (Mn)** | 0.0 - 0.05 | | **Zinc (Zn)** | 0.0 - 0.07 | | **Other Elements (Each)** | ≤ 0.03 | | **Other Elements (Total)** | ≤ 0.10 | *Note: The "A" in 1050A (per EN standards) indicates a controlled impurity limit for iron and silicon, ensuring consistent performance, especially for anodizing.* **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** | 222 W/m·K | | **Coefficient of Thermal Expansion** | 23.5 µm/m·K (20-100°C) | | **Modulus of Elasticity** | 69 GPa (10,000 ksi) | **4. Mechanical Properties (Typical)** Mechanical properties are dependent on the temper (condition). | Temper | Tensile Strength (MPa) | Yield Strength (0.2% Offset, MPa) | Elongation (% in 50mm) | | :--- | :--- | :--- | :--- | | **O (Annealed)** | 75 - 105 | 25 - 35 | 35 - 45 | | **H14 (Work Hardened)** | 120 - 145 | 110 - 130 | 5 - 10 | | **H18 (Full Hard)** | 155 - 180 | 145 - 165 | 2 - 5 | *Key Characteristics:* * **Excellent Corrosion Resistance:** Its high purity makes it highly resistant to atmospheric corrosion, forming a protective oxide layer. * **High Formability:** In the annealed (O) condition, it is extremely ductile and ideal for deep drawing, spinning, and complex bending. * **Superior Finishing Qualities:** It is exceptionally well-suited for anodizing, producing a bright, clear, and uniform surface finish. It also polishes to a high luster. * **Good Weldability:** Can be readily welded using all common methods. **5. Product Applications** 1050A aluminum is supplied in various forms, including sheet, strip, plate, foil, wire, and extruded sections. Its applications are diverse: * **Architectural & Decorative:** Roofing, wall cladding, ceiling panels, decorative trim, and nameplates, often after anodizing or painting. * **Chemical & Food Industry:** Tanks, vessels, and piping for handling chemicals and food products due to its non-toxicity and corrosion resistance. * **Electrical Components:** Busbars, conductors, and capacitor shells where good conductivity is required. * **Heat Exchangers & Radiators:** Fins and components benefiting from its thermal conductivity. * **Reflectors:** For light fixtures, solar concentrators, and thermal insulation due to its high reflectivity. * **General Sheet Metal Work:** Kitchen utensils, signs, and enclosures. * **Packaging:** Foil stock for packaging applications. **6. International Standards** 1050A aluminum is recognized under various international standard systems. It is important to note the difference between 1050 and 1050A, primarily in the EN system. | Standard System | Equivalent Designation | | :--- | :--- | | **ISO** | Al 99.5 (ISO 209) | | **EN (Europe)** | **EN AW-1050A** [Al99.5] | | **ASTM (USA)** | ASTM B491 (Wire), 1050 (The "A" is an EN designation) | | **UNS (USA)** | UNS A91050 | | **JIS (Japan)** | A1050 | | **GB (China)** | 1050A | --- **Summary:** **1050A Aluminum Alloy** is a fundamental, high-purity aluminum grade valued for its **excellent all-round performance**. It offers an optimal balance of **very good corrosion resistance, high formability, and superior surface finishing qualities**, making it a first-choice material for architectural, decorative, and general industrial applications. Its specific controlled composition (1050A) ensures consistency and reliability, particularly for critical anodized finishes.
