Component Specifications

Definition
The alloy matrix in high-purity magnesium alloy billets refers to the continuous metallic phase that forms the bulk of the material, composed primarily of magnesium with carefully controlled alloying elements such as aluminum, zinc, manganese, or rare earth elements. This matrix determines the fundamental mechanical, thermal, and corrosion properties of the billet, serving as the foundation for subsequent processing into finished products.
Working Principle
The alloy matrix functions as the structural backbone of magnesium alloy billets through solid solution strengthening and intermetallic phase formation. It provides load-bearing capacity, thermal stability, and corrosion resistance by maintaining a homogeneous metallic structure with controlled grain boundaries and minimal impurities.
Materials
High-purity magnesium (≥99.8%) with alloying elements: Aluminum (3-9%), Zinc (0.5-2%), Manganese (0.2-0.8%), and trace rare earth elements (<0.5%). Impurity limits: Iron <0.005%, Nickel <0.002%, Copper <0.05%.
Technical Parameters
  • Density 1.74-1.85 g/cm³
  • Hardness 60-85 HB
  • Elongation 8-15%
  • Grain Size ASTM 5-8
  • Melting Point 650-700°C
  • Yield Strength 150-250 MPa
  • Tensile Strength 200-320 MPa
Standards
ISO 16220, ASTM B107, DIN 9715, GB/T 5153
