Aluminium-Scandium(AL-Sc) Details

This product is an aluminum scandium master alloy containing scandium. It is a powerful grain refiner and an effective recrystallization inhibitor of aluminum alloy, which can effectively improve its strength, hardness, welding performance, corrosion resistance, etc., and is applied to aerospace, transportation and other fields.

Aluminium-Scandium(AL-Sc) Scope of application

It is suitable for long-term modification of eutectic and hypereutectic Al Si alloy (metal mold casting) or addition of Scandium element.

Aluminium-Scandium(AL-Sc) Usage

1. Bake and dry before use.

2. Adding temperature: 720 ～ 760 ℃.

3. Dosage of this product: the dosage of Scandium Sc is 0.1-0.5% (generally 0.2-0.3%), and the dosage of master alloy is converted accordingly.

4. Adding method: after refining treatment, raise the temperature to the required temperature, remove the scum, lightly put the product into the aluminum liquid, stir evenly, stand for 10-20 minutes, remove the slag and pour the test rod. When the fracture inspection is normal, pour it.

5. Fracture inspection: size of test bar in front of furnace Φ twelve × 100, normal fracture is gray white velvet, with dense structure and no silicon bright spot
