Rare Earth Aluminium Alloys: Strong & Heat Resistant
Product Features
Enhance the performance of your aluminum products with our Aluminum Rare Earth Alloy, featuring mixed rare earth elements such as lanthanum, cerium, praseodymium, and neodymium. These elements refine grains, purify melts, and improve both the strength and plasticity of alloys, leading to superior processing performance.
- Performance Improvement: Rare earth elements refine grains, purify melts, and enhance alloy strength and plasticity.
- Impurity Reduction: Minimize the harmful effects of silicon impurities on electrical properties in electrical aluminum.
- Deterioration and Purification Effect: Optimize the morphology and distribution of silicon, ensuring long-lasting effects that are inheritable through remelting and modification.
Usage and Dosage
Follow these operation steps for optimal results:
- Bake and dry the alloy before use.
- Ensure the adding temperature exceeds 720℃.
- Add 0.03-0.15% rare earth elements to the aluminum liquid, adjusted based on the alloy type and demand. Typically, use 0.3-1.5% relative to the aluminum being treated.
Operation Steps
- Place the alloy block into the aluminum liquid and stir evenly after melting.
- Let it stand for over 10 minutes, remove slag, and pour a test rod to inspect the fracture.
- Fracture Inspection: A normal fracture should appear silver-white with a velvety texture, fine and uniform grains, and no silicon bright spots.
Packing and Storage Methods
- Alloys are packaged with materials that prevent contamination and damage during transport and storage.
- Store in a dry, cool place to avoid moisture and deterioration.
Application Scenarios
- Aerospace: Ideal for high-temperature components like aircraft engine turbine blades.
- Automobile Industry: Perfect for manufacturing engine parts to enhance wear resistance, thermal stability, and energy efficiency.
- Chemical Industry: Used in manufacturing chemical equipment and pipelines for its corrosion-resistant properties.
- Electronic Technology: Suitable for electronic components, circuit boards, and connectors, especially in high-frequency electronic devices.
- Oil and Gas Extraction: Used for high-temperature and corrosion-resistant oil drill bits and pipelines.
- Medical Devices: Suitable for medical devices, artificial joints, and dental materials due to biocompatibility and corrosion resistance.
- Optical Devices: Ideal for manufacturing lasers, infrared sensors, and optical communication devices.
Preparation Methods
There are various preparation methods, each offering unique advantages:
- Smelting Method: The most traditional and common, involving melting, adding rare earth elements, stirring, and solidifying.
