Rare-earth master alloys for aerospace lightweight components>

Our Magnesium-Samarium master alloy is independently vacuum-melted in our Ganzhou factory. It is a high-stability rare earth magnesium master alloy, designed to improve the thermal stability and mechanical fatigue resistance of magnesium alloys. It features uniform samarium element distribution and stable modification effect.

We provide standard industrial grades and support customized samarium content to meet personalized R&D and production needs. All samarium raw materials are 3N/4N high-purity heavy rare earth metals, ensuring ultra-low impurity content and stable batch quality.

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