Magnesium Yttrium Alloy MgY Master Alloy For High Temperature Strength Of Magnesium Alloy
Name: Magnesium Yttrium Alloy Molecular formula: MgY
Size: according to user's requirements Y content: 20%, 25%, 30%(wt)
Description: Yttrium can be used as additive in magnesium alloy. Therefore, the Mg-Y master alloy can not only reduce the oxidation loss and cost, but also has the advantages of convenient storage and transportation, simple operation, pollution-free, stable composition and reliable quality. Magnesium yttrium alloy has low specific gravity (no more than 1.9g / cm3) and high strength, so it is widely used in aerospace industry to improve the heat resistance, corrosion resistance and high temperature strength of magnesium alloy.

Package: Conventional packaging, 50kg per bag in iron drum packaging, also provide small package: 100g, 500g, 1kg, 5kg and other small packaging.
Used: It is widely used in the aerospace industry to improve the heat resistance, corrosion resistance and high temperature strength of magnesium alloys. Purification function, yttrium can remove impurities such as hydrogen, deoxidation and iron, reduce porosity and porosity of castings, and improve fluidity. The grain and dendrite are refined by modification. Yttrium has a high age hardening effect in magnesium alloy, which improves the room temperature strength. The addition of yttrium has better heat resistance and high temperature creep resistance than the addition of other rare earth elements. The working temperature is increased to 350℃. The addition of yttrium can improve the corrosion resistance of magnesium alloy.
