Sand permanent-mold, and die casting are all well developed for magnesium alloys, die casting being the most popular. Although magnesium is about twice as expensive as aluminium, its hot-chamber die-casting process is easier, more economical, and 40% to 50% faster than cold-chamber process required for aluminium. Forming behavior is poor at ...
Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand—known as casting sand—as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries. In 2003, over 60% of all metal ...
Haley Industries (originally known as Light Alloys Limited) was founded in 1952 in Haley Station, Ontario (approximately 100 km west of Canada's capital city Ottawa).It was set up with the support of the Canadian government in order to contribute to the development of Canada's fledgling aerospace industry.

The casting is usually a fine-grained casting with an especially fine-grained outer diameter, due to the rapid cooling at the surface of the mold. Lighter impurities and inclusions move towards the inside diameter and can be machined away following the casting. Casting machines may be either horizontal or vertical-axis. [1]
Semi-solid metal casting (SSM) is a near net shape variant of die casting. [1] The process is used today with non-ferrous metals, such as aluminium , copper , [ 2 ] and magnesium . It can work with higher temperature alloys that lack suitable die materials.
An engine block with aluminum and magnesium die castings. Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process.
A lot of companies continued production after the 1960s, although in lower quantities. Modern scientific and engineering developments led to significant improvements in the quality of magnesium wheels, including high-tech anti-corrosion treatment that extends the lifecycle of a wheel to match or even exceed the life cycle of comparable ...
Permanent mold casting. Permanent mold casting is a metal casting process that employs reusable molds ("permanent molds"), usually made from metal. The most common process uses gravity to fill the mold, however gas pressure or a vacuum are also used. A variation on the typical gravity casting process, called slush casting, produces
