Aluminum-magnesium engineering alloy

Aluminum-magnesium alloys are important metals in the automotive industry. Among other things, it improves fuel efficiency, reduces emissions and resists corrosive environments. Here is a quick overview of this material. You can also learn about the AZ91D, AM60B and AM50A. These alloys are extremely durable and can help you build the best car possible. But before you choose an alloy, make sure it's right for your project.

AZ91D

AZ91D is a two-phase alloy consisting of a phase and b phase. Phase a has a fine layered microcomponent (three in Figure 1), while phase b is characterized by large b objects interlocking to form a fine network. This makes the AZ91D an excellent choice for aerospace and defense applications.

Diffusion coating treatment is the process of combining two different processes to form a composite material. An aluminum alloy coating is a thin layer of metal coated with magnesium oxide. The coating is then formed in a vacuum chamber and cooled using high pressure gas. The Al-Mg ions react with each other to form a solid solution. As Al deposition continued, active Al atoms diffused into the AZ91D substrate. This process is driven by a chemical gradient, and the aluminum concentration in the composite surface layer increases over time.

AM60B

This article will discuss the differences between AZ91D and AM60B aluminum-magnesium engineering. The former has smaller granularity and is more durable than the latter. The former is suitable for Lamp Parts Factory low cycle applications. The AZ91D is a cheaper alternative, but not as versatile as the AM60B. Its elongation and tensile properties are closely related to fatigue strength and are therefore not recommended for structural use.

This alloy is not suitable for casting, but can be used for high performance parts that require low temperature hardness. The hardness of the alloy increases during cold rolling, thereby reducing the number of heat-treated parts. Thicker sections can be used for casting, but will be more expensive than thinner sections. The thicker the part, the harder it is.

AM50A

AM50A aluminum-magnesium engineering alloy is the best magnesium alloy for high-strength, light-weight applications. They exhibit better mechanical properties and lower grain size than other magnesium alloys. Tensile strength, tensile toughness and deformation resistance are some of the key properties of this alloy. These alloys can be used in a variety of applications.

AM50A Aluminum Magnesium Engineering has many uses, from aerospace to medical applications. The material's high strength and fatigue resistance make it a popular choice for composites. Its low density and resistance to heat and corrosion make it a valuable material for the aerospace and defense industries. AM50A aluminum-magnesium engineering can also be used to manufacture medical devices and other high-strength applications.

AM20

AM20 aluminum-magnesium engineering alloy is a high-strength cast magnesium alloy with constant Mn content. These alloys have different thermal conductivity and hardness values, depending on their composition. Their thermal conductivity increases with increasing temperature. Their coefficient of thermal expansion (CTE) depends on the temperature during the first thermal cycle. Their hardness values ​​decrease with increasing aluminum content.

Alloying elements can refine the grain size and improve the mechanical properties of AM magnesium alloys. For example, the AM50 alloy has an ultimate tensile strength of 233 MPa and a high elongation value of 16.3%. The AM60 alloy has a relatively high ductility of 18%. In addition, the inclusion of Ti or Sc has no effect on ductility. More sophisticated alloying methods can reduce the amount of metal used in the process and introduce better properties.

AM20B

AM20B aluminum-magnesium engineering alloy has been developed for use in composite materials. This alloy is characterized by a hard b-phase with reduced ductility. It also exhibits discontinuous patterns and forms networks around grain boundaries. The material is suitable for the manufacture of aerospace, automotive and marine components. AM20B is also useful in many other applications. However, its properties are mainly suitable for light weight, high strength and ductility applications.

Although magnesium alloys are the easiest structural metals to machine, machining them presents some risks, especially at high cutting speeds. This is because the magnesium alloy fragments must be heated near the melting point to cause ignition. This process also results in a raised undercut edge, which will be referred to as "side buildup".
