The composition of common magnesium alloy models generally includes elements such as magnesium, silicon, aluminum, zinc, manganese, and titanium. The magnesium element comes from magnesium ingot, usually Mg Ingot 99.9 or Mg Ingot 99.95. The silicon element comes from Silicon Metal. The aluminum element can be aluminum ingots or electrolytic aluminum. Zinc element generally uses zinc ingots. Manganese element uses electrolytic manganese flakes.
Common magnesium alloy models include:
Mg-Al-Zn series Mg Alloy Models
AZ31B is a commonly magnesium alloy model, it composed of 3% aluminum and 1% zinc, and its weight is about 30% lighter than aluminum alloy. AZ31B has good corrosion resistance, good processability and strength, and is capable in aerospace, automotive, electronics and other fields. AZ61A
AZ61A is an aluminum-zinc-magnesium alloy that is stronger than AZ31B. It is also suitable in aviation, automobiles, medical and other fields because of its lightweight, high strength and other properties.
AZ91D
AZ91D is also a regular magnesium alloy grade, consisting of 9% aluminum and 1% zinc, which is stronger and more corrosion-resistant than AZ31B. Application areas include automobiles, electronics, tools, etc.
Mg-Ca series Magnesium Alloy Models
Mg-Ca30
Mg-Ca30 is a magnesium-calcium alloy consist of 30% calcium and 70% magnesium. In brief, it has high strength, low density and excellent mechanical properties. Its application fields include aerospace, automobiles, ships, etc.
Mg-Ca50
Mg-Ca50 is more tough and stretch-resistant than Mg-Ca30, and is suitable for manufacturing high-speed friction tools, pneumatic plugs and other fields. Because of its mechanical properties are better than international standards.
Mg-Y series Alloy Common Models
WE43
WE43 is composed of 4% yttrium, 2% rare earth metals, 0.5% zinc and the remainder of the alloy. Compared with AZ91D, WE43 has better strength and fracture toughness. As a result, it is widely used in aerospace components, artillery shells, engine components and other fields.
Mg-Y-Zr
Mg-Y-Zr contains of 4% yttrium, 3% zirconium and 0.5% zinc. So it has higher strength and better mechanical properties and is applying in lightweight design, high-load skeletons and structures.
In conclusion, the above are several common magnesium alloy grades. Each alloy has its own unique characteristics and application fields. The appropriate alloy can be selected according to specific needs.
