Aluminium-beryllium Master Alloy，Aluminium beryllium Alloy，AlBe Alloy，E FORU

**Product Datasheet: Aluminium-Beryllium Master Alloy (Al-Be Alloy)** **Version:** 1.0 | **Date:** 2025-04-02 --- ### **1. General Overview** Aluminium-Beryllium Master Alloy (Al-Be Alloy) is a specialized material primarily used to introduce beryllium into aluminium and other non-ferrous alloy systems. Beryllium acts as a potent grain refiner and oxide film modifier, significantly improving the fluidity, castability, and surface finish of aluminium alloys. It is particularly valuable in applications requiring reduced oxidation and improved melt quality. --- ### **2. International Standards** Al-Be master alloys are governed by several international standards: - **ASTM:** ASTM B85 (Aluminum-Alloy Die Castings) - **AMS:** AMS 7720 (Beryllium-Aluminum Alloy Castings) - **AWS:** A5.10 (Beryllium-containing aluminum welding electrodes) - **EU Directive:** 2011/65/EU (RoHS) - beryllium restrictions - **Typical Master Alloy Grades:** Al-5%Be, Al-10%Be, Al-15%Be --- ### **3. Chemical Composition (Weight %)** Typical composition ranges for Al-Be master alloy: | Element | Content (%) | Role & Remarks | |------------------|-------------------|------------------------------------------| | Beryllium (Be) | 2.0 – 15.0 | Primary modifying element | | Silicon (Si) | ≤ 0.20 | Impurity control | | Iron (Fe) | ≤ 0.25 | Impurity control | | Copper (Cu) | ≤ 0.05 | Impurity control | | Other Impurities | ≤ 0.15 total | — | | Aluminium (Al) | Balance | Base metal | --- ### **4. Physical Properties** | Property | Value / Range | |---------------------------|-----------------------------------| | Density | 2.6 – 2.8 g/cm³ (varies with Be content) | | Melting Range | 580 – 650°C | | Solidification Behavior | Forms Al-Be intermetallic phases | | Hardness (Brinell) | 40 – 70 HB (master alloy form) | | Thermal Conductivity | 150 – 200 W/m·K | | Electrical Conductivity | 40 – 50 % IACS | --- ### **5. Key Characteristics & Advantages** - **Oxidation Resistance:** Significantly reduces surface oxidation in molten aluminium - **Grain Refinement:** Produces fine, uniform grain structure in castings - **Improved Fluidity:** Enhances mold filling characteristics - **Surface Finish Improvement:** Produces superior casting surface quality - **Gas Reduction:** Helps minimize hydrogen absorption in melts --- ### **6.
