2037 Aluminum alloy,Aluminum 2037 alloy,E FORU

### **Product Datasheet: 2037 Aluminum Alloy** **1. Overview** 2037 Aluminum Alloy is a high-purity, high-conductivity aluminum-copper alloy. It is part of the 2xxx series (Al-Cu) of aluminum alloys, which are known for their excellent strength and machinability. Unlike alloys like 2024 or 2014, 2037 is characterized by its relatively high aluminum content and controlled levels of impurities, making it particularly suitable for applications requiring superior electrical conductivity combined with good mechanical properties. It is often supplied in various tempers to suit specific application needs. **2. International Standards** 2037 Aluminum alloy is recognized under several major international standards systems: * **UNS:** UNS A92037 * **ASTM:** ASTM B211 (Standard Specification for Aluminum and Aluminum-Alloy Bar, Rod, and Wire) * **SAE:** SAE J454 (Recommended Practice for Chemical Compositions of Wrought Aluminum Alloys) * **AA (Aluminum Association):** AA 2037 (The defining standard for composition and temper) * **AMS:** AMS 4119 (Aerospace Material Specification for wire and rod) *Note: Specific forms (sheet, plate, wire) may be governed by other ASTM standards such as B209.* **3. Chemical Composition (Weight %)** The composition conforms to the limits set by the Aluminum Association (AA). | Element | Content (%) | | :--- | :--- | | **Aluminum (Al)** | Balance | | **Copper (Cu)** | 0.20 - 0.50 | | **Iron (Fe)** | ≤ 0.50 | | **Silicon (Si)** | ≤ 0.30 | | **Manganese (Mn)** | ≤ 0.10 | | **Magnesium (Mg)** | ≤ 0.10 | | **Zinc (Zn)** | ≤ 0.10 | | **Chromium (Cr)** | ≤ 0.10 | | **Titanium (Ti)** | ≤ 0.15 | | **Others (Each)** | ≤ 0.05 | | **Others (Total)** | ≤ 0.15 | **4.

Mechanical Properties (Typical Values)** *Mechanical properties are highly dependent on the temper. The following are typical ranges.* | Property | O (Annealed) | H18 (Full Hard) | | :--- | :--- | :--- | | **Tensile Strength (Ultimate)** | 95 - 125 MPa (14 - 18 ksi) | 185 - 220 MPa (27 - 32 ksi) | | **Tensile Yield Strength (0.2% Offset)** | 35 - 70 MPa (5 - 10 ksi) | 170 - 200 MPa (25 - 29 ksi) | | **Elongation at Break** | 20 - 30% | 2 - 6% | | **Modulus of Elasticity** | 70.0 - 71.0 GPa (10,150 - 10,300 ksi) | | **Shear Strength** | ~ 75 MPa (O) / ~ 110 MPa (H18) | | **Fatigue Strength** | ~ 55 MPa (For 500 million cycles) | **6. Key Characteristics & Advantages** * **Excellent Electrical Conductivity:** Its high purity and specific composition give it conductivity significantly higher than many other 2xxx series alloys, making it a lightweight alternative to copper in some electrical applications. * **High Machinability:** 2037 aluminum exhibits excellent machinability, often rated as "Good" to "Excellent," allowing for high-speed machining and good surface finish. * **Good Strength:** While not as strong as high-performance alloys like 7075 or 2024, it offers a good balance of strength and conductivity, especially in strain-hardened tempers (H1x). * **Light Weight:** Like all aluminum alloys, it offers a significant weight advantage over copper and steel. * **Good Corrosion Resistance:** It demonstrates better general corrosion resistance than higher-copper 2xxx series alloys, though it is not as resistant as 3xxx or 5xxx series alloys. **7. Product Applications** 2037 Aluminum Alloy is commonly used in applications that leverage its unique combination of conductivity, machinability, and strength. * **Electrical Components:** Bus bars, conductive terminals, and electrical connectors. * **Machined Parts:** Screw machine products, fittings, and fasteners where good machinability is critical. * **General Manufacturing:** Hardware, hinges, and various small structural components. * **Automotive:** Certain non-critical electrical and structural parts. **8. Availability** 2037 is typically supplied as: * Wire, Rod, and Bar (for machining) * Sheet and Strip --- **Disclaimer:** The information provided herein is for reference purposes only.
