How is magnesium alloy plate produced？

Magnesium alloy plate can be produced through a process called casting or extrusion. Here are the general steps involved in each of these methods:

Casting Method:

a. Melting: Magnesium alloy, typically in the form of ingots or chips, is melted in a furnace at temperatures around 700-750 degrees Celsius (1300-1380 degrees Fahrenheit). Magnesium alloys are used to enhance the mechanical properties of pure magnesium.

b. Refining: During the melting process, refining agents are added to remove impurities and improve the quality of the molten metal.

c. Mold Preparation: A mold is prepared with the desired shape and dimensions of the magnesium plate. The mold can be made of steel or other materials suitable for casting.

d. Pouring: The molten magnesium alloy is poured into the mold. Care must be taken to ensure proper filling of the mold to avoid defects.

e. Solidification: The molten metal cools and solidifies within the mold, taking the shape of the mold cavity. Cooling rates and controlled solidification techniques may be employed to optimize the material properties.

f. Removal and Finishing: Once the metal has solidified, the mold is opened, and the magnesium plate is removed. The plate may undergo further processing steps, such as trimming, grinding, or surface treatment, to achieve the desired final dimensions and surface finish.

Extrusion Method:

a. Billet Preparation: Magnesium alloy is first cast into billets, which are cylindrical or rectangular bars of solid metal. The billets are typically larger in cross-section than the desired plate thickness.

b. Heating: The billet is heated to a specific temperature, usually around 350-450 degrees Celsius (660-840 degrees Fahrenheit), to make it more malleable for the extrusion process.

c. Extrusion: The heated billet is pushed through a specially designed die using a hydraulic press or an extrusion machine. The die has an opening with the shape and dimensions of the desired magnesium plate.

d. Cooling and Cutting: The extruded magnesium plate is cooled and cut into the desired lengths. The cooling process can be controlled to achieve the desired material properties.

e. Finishing: The cut magnesium plates may undergo additional processing steps, such as heat treatment, surface treatment, or machining, to meet specific requirements.

It's important to note that the exact production process may vary depending on the specific requirements, equipment, and techniques used by different manufacturers.
