AZ91D has excellent corrosion resistance. Its ingot most commonly used magnesium die casting alloy.

XI'AN YUECHEN METAL PRODUCTS CO., LTD. (XYMCO) produces the semi-continuous cast billet and slab from the primary AZ91D ingot.

Semi-continuous Cast magnesium alloy billet and slab is manufactured as the starting material for other magnesium products, such as plate, forgings and extrusions. However, it has been frequently found that the cast billet and slab is suitable for machining into prototypes, thus avoiding expensive tooling, and in some cases for production where the size of the finished items is outside economic casting or extrusion dimension or minimum economic production.

Semi-continuous Cast Magnesium Alloy Billet and Slab is supplied to clients on the compositional and homogenized condition.

For AZ91D cast billet: OD 90 – 800mm, length is 2000mm

For AZ91D cast slab: max. 350 x 1100 x 3000mm

Both the billet and slab, we can cut to size as per customer’s requirement
