Aluminum Erbium Alloy AlEr Master Alloy For Refine Aluminum Alloy Grains
Name: Aluminum Erbium Alloy Molecular formula: AlEr
Size: according to user's requirements Er content: 10%, 20%, 30%(wt)
Description: The microstructure and properties of Aluminum Erbium Alloy are analyzed. It is considered that Er is another effective microalloying element after Al alloy relay Sc. the addition of micro Er can refine the as cast grains of the alloy, and can largely keep the elongation of the alloy unchanged It can hinder or delay the recrystallization process, and increase the recrystallization temperature of the alloy by about 50 ℃, which is conducive to the improvement of high temperature properties.

Package: Conventional packaging, 50kg per bag in iron drum packaging, also provide small package: 100g, 500g, 1kg, 5kg and other small packaging.
Used: Aluminum erbium alloy was used to refine the grain of aluminum alloy to improve the stress corrosion resistance and ductility of aluminum alloy. Adding a very small amount of erbium in aluminum alloy can obviously refine the grain, and the cost of aluminum erbium alloy is far lower than that of aluminum scandium alloy. If aluminum erbium alloy is used in industry instead of aluminum scandium alloy, it is of great significance from the economic point of view.
