Title:

MAGNESIUM-BASED ALLOY AND METHOD FOR THE PRODUCTION THEREOF

Document Type and Number:

WIPO Patent Application WO/2003/056049

Kind Code:

A1

Abstract:

The inventive magnesium-based alloy comprises the following components: 2.6-3.6 mass % of aluminium, 0.11-0.25 mass % of zinc, 0.24-0.34 mass % of manganese, 0.8-1.1 mass % of silicium, 0.05-0.10 mass % of calcium, the rest being magnesium. The inventive method for producing said alloy consists in loading alloying components of aluminium, zinc, manganese and silicium in the form of a ready-made solid master alloy of aluminium-zinc-manganese-silicium, casting molten magnesium, introducing a titanium-containing fusion cake together with a flux agent and continuously agitating said cake. Said titanium-containing fusion cake being introduced, magnesium is cooled and calcium is loaded under the layer of magnesium. Afterwards, the alloy is soaked and casted. Said invention makes it possible to produce the alloy provided with mechanical properties suitable for high-pressure casting.
