Aluminum-Samarium (Al-Sm) Master Alloy | High-Stability Rare Earth Aluminum Alloy

Our Aluminum-Samarium master alloy is independently vacuum-melted in our Ganzhou factory. It is a high-stability rare earth aluminum intermediate alloy, specially used to improve the thermal stability, fatigue resistance and long-term service performance of aluminum alloys. Samarium elements are evenly distributed with stable modification effect.

We supply standard industrial grades and support customized samarium content. Adopting high-purity 3N/4N samarium raw materials, our products feature ultra-low impurities and consistent batch quality.

Important Notice: This product contains controlled heavy rare earth element (Samarium). Export from China requires official dual-use item export license.

Custom samarium content and special specifications are available.
