Bio-medical magnesium alloys

Bio-medical magnesium alloys refer to magnesium alloys with biodegradability and biocompatibility, used in the manufacturing of medical devices or implants such as vascular stents, bone internal fixation devices, and bone repair materials.

Bio-medical magnesium alloys and their grades

Rare Earth-Containing Magnesium Alloys: These alloys involve the addition of rare earth elements such as yttrium (Y), lanthanum (La), cerium (Ce), neodymium (Nd), etc., to enhance the mechanical properties and corrosion resistance. Examples of rare earth-containing magnesium alloy grades include WE43, WE54, LAE442, EK20, JDBM, and others.

Zirconium-Containing Magnesium Alloys: The addition of zirconium (Zr) in magnesium refines grain size and improves corrosion resistance. Examples of zirconium-containing magnesium alloy grades are ZK60, ZK61, ZE10, ZE21, ZC63, and others.

Aluminum-Containing Magnesium Alloys: The addition of aluminum (Al) in magnesium improves its strength and hardness. Examples of aluminum-containing magnesium alloy grades include AZ31, AZ61, AZ80, AZ91, AM50, AM60, and others.

Manganese-Containing Magnesium Alloys: These alloys incorporate manganese (Mn) to enhance corrosion resistance and antioxidation properties. Examples of manganese-containing magnesium alloy grades are M1A, M2A, M4A, M5A, M6A, and others.

Calcium-Containing Magnesium Alloys: The addition of calcium (Ca) in magnesium enhances biocompatibility and degradation rate. Examples of calcium-containing magnesium alloy grades include Mg-Ca, Mg-Ca-Zn, Mg-Ca-Sr, Mg-Ca-Mn, and others.

Our company can supply calcium-containing magnesium alloys, which exhibit strong stamping formability and comply with the national food safety standard GB9684-2011. These alloys can be used for manufacturing heart stents, medical bone nails.

Performance characteristics of Mg-Ca alloys:

Biocompatibility: The addition of calcium enhances the biocompatibility of the alloy in the body.

Biodegradability: The alloy can gradually degrade into non-toxic ions in the body, eliminating the need for a second surgery for implant removal.

Mechanical Properties: Mg-Ca alloys have good strength, with specific mechanical properties depending on the calcium content and other added elements in the alloy.

Degradation Rate: The degradation rate of Mg-Ca alloys can be controlled by adjusting the calcium content, with higher calcium content generally leading to faster degradation.

Corrosion Resistance: Mg-Ca alloys typically exhibit good corrosion resistance
