This is a type of product is a widely used in general welding material with the magnesium of 5%, which can be use in jointing oe overlay  forging and casting alloys processing.And this product is of high toughness, good forgeability, and well anti-corrosiveness. Furthermore, this is a good chioce for colour-match in welding after anodic process.
product useageship-building, space shuttle, etc
