1050-H16 Aluminum alloy,Aluminum 1050-H16 alloy,E FORU

Of course. Here is a comprehensive English product introduction for **1050-H16 Aluminum Alloy**. --- ### **1050-H16 Aluminum Alloy Product Introduction** **1. Overview** 1050-H16 is a specific strain-hardened temper of the commercially pure 1050 aluminum alloy. As part of the 1xxx series, it is a non-heat-treatable alloy whose strength is derived primarily from cold working. The "H16" temper designation indicates a strain-hardened level that is three-quarters hard (i.e., strength halfway between H14 and H18). This temper offers a higher strength and stiffness compared to H14, while still retaining a degree of formability, making it suitable for applications requiring a more rigid sheet without resorting to the full-hard condition. **2. Chemical Composition (Typical, % by Weight)** The base composition is that of 1050 aluminum, conforming to international standards. | 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 high minimum aluminum content (99.5%) is responsible for the alloy's excellent corrosion resistance, electrical and thermal conductivity, and workability.* **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 for H16 Temper)** The "H16" temper defines the mechanical properties, which are achieved through a specific degree of cold reduction after annealing. | Property | Value | | :--- | :--- | | **Tensile Strength** | 140 - 165 MPa | | **Yield Strength (0.2% Offset)** | 125 - 150 MPa | | **Elongation (% in 50mm)** | 4 - 8 % | | **Hardness (Brinell)** | ~ 39 HB | *Key Characteristics of H16 Temper:* * **Higher Strength than H14:** Provides greater resistance to bending and denting, offering improved structural rigidity. * **Good Corrosion Resistance:** Maintains the excellent corrosion resistance inherent to the 1050 base alloy. * **Limited, but Sufficient Formability:** While less formable than H14 or O tempers, it remains suitable for moderate bending and simple forming operations. It is not recommended for severe drawing or spinning. * **Excellent Surface Quality:** The surface is ideal for anodizing, painting, and other finishing processes. **5. Product Applications** 1050-H16 aluminum is predominantly supplied as sheet and strip. Its key advantage is providing a stiffer, more robust panel than H14, which is critical for many flat and semi-structural applications. * **Architectural Cladding & Roofing:** Where increased rigidity is required for larger spans or to resist wind loading. * **Sheet Metal Work:** For enclosures, cabinets, and covers that require less flex and more dimensional stability. * **Signage & Nameplates:** Providing a flat, stable, and durable base for printing and engraving. * **Reflectors & Light Fittings:** Where a stiffer sheet is needed to maintain shape and form. * **Partitions & Ceiling Panels:** In construction and interior design. * **General Engineering Components:** Used for blanks, shims, and spacers where specific strength and flatness are required. **6. International Standards** 1050-H16 is recognized under various international standard systems. The temper designation (H16) is consistent across them. | Standard System | Equivalent Designation | | :--- | :--- | | **ISO** | Al99.5 H16 (ISO 209) | | **EN (Europe)** | EN AW-1050A H16 | | **ASTM (USA)** | ASTM B491 (Sheet/Strip), Alloy 1050 H16 | | **UNS (USA)** | UNS A91050 H16 | | **JIS (Japan)** | A1050 H16 | | **GB (China)** | 1050A H16 | --- **Summary:** **1050-H16 Aluminum Alloy** is a **three-quarters hard temper** that occupies a critical position in the aluminum temper spectrum. It delivers **significantly higher strength and stiffness than the H14 temper**, making it the preferred choice for applications where the added flexibility of H14 is insufficient and the limited formability of H18 is not required. It combines this enhanced mechanical performance with the classic benefits of pure aluminum: excellent corrosion resistance, good surface finish, and high conductivity. It is an essential material for architectural and industrial applications demanding a rigid, yet workable, aluminum sheet.
