Magnesium-Lanthan Main Alloy Description
Magnesium-Lanthan main alloy is a specialised alloy composed of magnesium (Mg) with an elevated concentration of lanthanum (La). It is produced under controlled processes to enhance the performance metrics of magnesium alloys. The addition of lanthanum improves mechanical properties, including tensile strength, ductility and corrosion resistance. This master alloy is used in the production of lightweight, high-strength components for the aerospace, automotive and electronics industries.

Application of Magnesium-Lanthan Master Alloy
Rare earths (RE) have been alloyed with magnesium (Mg) successfully. The addition of rare earths refines grain size and reduces anisotropy. This process improves the ductility of magnesium alloys. RE elements form a dispersion of thermally stable precipitates with melting points exceeding 620 °C. Given that precipitates in the Mg-Zn system melt at approximately 340 °C, they show poor thermal stability and increase the risk of hot cracking.
Packaging of Magnesium-Lanthan Master Alloy
The Magnesium-Lanthan master alloy produced by SAM is handled with care. This is done to minimise damage during storage and transport, thereby preserving product quality in its original form.
