Magnesium Alloy Sheet Grades

Magnesium alloy sheets are thin, flat sheets made from magnesium alloys. Similar to magnesium alloy plates, magnesium alloy sheets offer the advantages of lightweight construction, good strength-to-weight ratio, and corrosion resistance. They are used in various industries, including aerospace, automotive, electronics, and general engineering.

The selection of magnesium alloy sheet grades depends on the specific requirements of the application. Here are some commonly used magnesium alloy sheet grades:

AZ31: This magnesium alloy grade, with approximately 3% aluminum and 1% zinc, is widely utilized in sheet form. It offers good formability, weldability, and moderate strength. AZ31 sheets find applications in aerospace, automotive, and electronics industries. $10 to $18 per kilogram.

AZ91: AZ91 magnesium alloy sheets contain approximately 9% aluminum and 1% zinc. They provide higher strength compared to AZ31, making them suitable for applications that require increased load-bearing capacity. AZ91 sheets are used in automotive components, electronic devices, and sporting goods. $12 to $20 per kilogram.

AM50 and AM60: These magnesium alloy grades, containing aluminum and manganese, offer good strength, castability, and corrosion resistance. AM50 and AM60 sheets are used in automotive parts, such as instrument panels, dashboards, and structural components.The price of AM60 wrought magnesium alloy sheets and strips can range from $13 to $22 per kilogram.

ZK60: ZK60 is a magnesium alloy grade with approximately 6% zinc and a small amount of zirconium. It exhibits excellent strength and impact resistance. ZK60 sheets find applications in the aerospace industry, as well as sporting goods and electronic devices.$14 to $24 per kilogram.

Secifications and Properties 

The specifications and Properties of magnesium alloy sheet

Sheet Thickness: Magnesium alloy sheets are available in various thicknesses, typically ranging from a few millimeters to a millimeter. The specific thickness required will depend on the application and the desired balance between weight and strength.

Sheet Dimensions: The dimensions of magnesium alloy sheets can vary based on the application and manufacturing capabilities. Standard sheet sizes typically range from small dimensions for specific components to larger sheets suitable for structural applications.

Surface Finish: The surface finish of magnesium alloy sheets can be specified based on the desired appearance and functional requirements. Common finishes include mill finish (as-produced), polished, or coated with protective films to enhance corrosion resistance or facilitate further processing.

Mechanical Properties: The mechanical properties of magnesium alloy sheets include tensile strength, yield strength, elongation, and hardness. These properties can be tailored by alloy composition and heat treatment processes to meet specific application requirements.

Corrosion Resistance: Magnesium alloys exhibit moderate corrosion resistance. However, additional protective coatings or surface treatments can be applied to enhance their resistance to corrosion in specific environments.
