Advance Magnesium Die Casting Supplier In China


It all starts with you. Our goal is to make your ideas come to life one layer at a time

In Die Casting Process,Magnesium alloy Corrosion and mechanical properties have many characteristics: fast heat dissipation, light weight, good rigidity, certain corrosion resistance and dimensional stability, impact resistance, wear resistance, good attenuation performance and easy recycling; in addition, It has the characteristics of high thermal and electrical conductivity, non-magnetic, good shielding and non-toxic.

The Advantage Of Magnesium Die Casting

  • Although the specific gravity of magnesium alloy is heavier than plastic, its strength and elastic modulus per unit weight are higher than that of plastic. Therefore, with the same strength parts, magnesium alloy parts can be made thinner and lighter than plastic. In addition, since the specific strength of magnesium alloy is higher than that of aluminum alloy and iron, the weight of aluminum or iron parts can be reduced without reducing the strength of the parts.
  • Magnesium alloy has the highest relative strength (ratio of strength to mass). The specific stiffness (ratio of stiffness to mass) is close to aluminum alloy and steel, much higher than engineering plastics.
  • In the elastic range, when magnesium alloy is subjected to impact load, the energy absorbed is half larger than that of aluminum alloy parts, so magnesium alloy has good shock resistance and noise reduction performance.
  • The melting point of magnesium alloy is lower than that of aluminum alloy, and its die-casting performance is good. The tensile strength of magnesium alloy castings is equivalent to that of aluminum alloy castings, generally up to 250 MPa, up to more than 600 MPa. Yield strength and elongation are not much different from aluminum alloys.
  • Magnesium alloy also has good corrosion resistance, electromagnetic shielding performance, and radiation protection performance, which can be 100% recycled and reused.
  • Magnesium alloy parts have higher stability. The casting line of die casting parts has high dimensional accuracy and can be processed with high precision.
  • Magnesium alloy has good die-casting forming performance, and the minimum wall thickness of die-casting parts can reach 0.5mm. It is suitable for manufacturing all kinds of die-casting parts of automobiles.
  • However, the coefficient of linear expansion of magnesium alloy is very large, reaching 25~26 μm/m℃, while that of aluminum alloy is 23 μm/m℃, brass is about 20 μm/m℃, structural steel is 12 μm/m℃, and cast iron is about 10 μm/m. m℃, rock (granite, marble, etc.) is only 5-9 μm/m℃, and glass is 5-11 μm/m℃.

Looking for precision magnesium alloy parts customized by an experienced and reliable die casting components manufacturer? Be-cu’s custom die casting services can be your ideal choice. We are very experienced in magnesium casting including magnesium die casting. With strong capability of casting a wide variety of magnesium steel alloys such as AZ91D, AM60B and AM50, we provide custom magnesium casting parts and components for industries and applications including automotive, food & dairy, machinery, medical, plumbing, watering, mining, petrochemical, electrical, energy, aerospace, submarine and others. We can assure you high quality magnesium castings. All of our magnesium alloy die casting components are subject to our rigorous inspection regime with designated inspectors, in-process inspection and a full final inspection completed on every part.

  • AZ91D: Most commonly used alloy for high pressure die casting. Offers good strength to weight ratio, very good corrosion resistance and excellent castability. This alloy is typically used for power-train and mechanical components where toughness is more important than deformation capability.
  • AM60B: Commonly used for automotive die castings for safety components such as instrument panel structures and seat frames. This alloy offers excellent ductility, energy absorbing properties, strength and castability.
  • AM50: With a lower aluminum content than AM60 this alloy offers a further increase in ductility but at a slightly reduced strength and a slight reduction in castability. It is typically used where the performance requirements demand elongation properties beyond that of AM60.
