More info

Magnesium-yttrium casting alloy is made by melting metal magnesium and metal yttrium. The common alloy ratio is 20-70% magnesium, and the ratio can also be customized. The magnesium-based master alloy has a uniform and stable composition, which can meet the requirements of magnesium alloy composition, microstructure regulation, and performance improvement. Our master alloys are produced in adherence to strict quality control practices, utilizing an induction melting and alloying process followed by static mold or direct chill (DC) continuous casting. Static cast finished products are available in a variety of forms including full or cut waffle ingot and notch bar ingot. MagnesiumYttrium (Mg-Y) Master Alloy is also available in the shot, screened, and sized to specification, and in bagged shots.

Magnesium Yttrium Master Alloy Properties

Property	Value/Description
Atomic Number (Primary Elements)	Mg: 12, Y: 39
Appearance	Silvery-metallic, often cast as ingots, rods, or shot
Crystal Structure	Hexagonal close-packed (HCP) for Mg, modified by Y addition
Density	~1.8–2.5 g/cm³ (Mg: 1.738 g/cm³, Y: 4.47 g/cm³, depends on Mg:Y ratio)
Melting Point	~600–1000°C (lower than pure Y: 1522°C, higher than Mg: 650°C, varies with Y content)
Boiling Point	Not well-defined for alloy; Mg: 1090°C, Y: 3338°C
Electrical Conductivity	Moderate, lower than pure Mg (~38% IACS) due to Y addition
Thermal Conductivity	~50–100 W/(m·K) (Mg: 156 W/(m·K), reduced by Y addition)
Hardness	Higher than pure Mg; Vickers hardness ~60–120 HV (depends on Y content and processing)
Tensile Strength	~135–285 MPa (varies with composition and heat treatment)
