Fabrication and synthesis of alloy
The metal material with metal characteristics formed by alloying process (melting, mechanical alloying, sintering, vapor deposition, etc.) of two or more metal elements or adding other non-metallic elements based on metal is often called alloy. However, the alloy may contain only one metal element, such as steel. (Steel is a general term for ferroalloys with carbon content between 0.02% and 2.00% by mass)

Physical classification of alloys
According to the name of the main metal with large content in the alloy, it is classified as a certain alloy. For example, the copper alloy with high content of copper mainly maintains the properties of copper. Type of alloy (1) mixture alloy (eutectic mixture): when liquid alloy is solidified, each component of the alloy is crystallized separately, such as soldering tin, bismuth cadmium alloy, etc;

Difference between wrought aluminum alloy and cast aluminum alloy
The fundamental difference between wrought aluminum alloy and cast aluminum alloy can be explained by the phase diagram of aluminum base binary alloy: the alloy with composition to the left of point B 'belongs to wrought aluminum alloy. When heated to a temperature higher than the solution line (BD), it can obtain single-phase α Solid solution, with good plasticity, is suitable for cold and hot pressure processing. Due to the development of melting and casting technology, the composition of some deformed aluminum alloys has expanded to F point. The alloy with composition to the right of point E belongs to cast aluminum alloy.

Features of aluminum alloy products
The alloy based on aluminum with other alloying elements is one of the light metal materials. In addition to the general characteristics of aluminum, aluminum alloys have specific characteristics of some alloys due to the different types and quantities of alloying elements. The density of aluminum alloy is 2.63 ～ 2.85g/cm3, with high strength（ σ B is 110~650MPa), the specific strength is close to that of high alloy steel, and the specific stiffness is higher than that of steel. It has good casting performance and plastic processing performance, good electrical conductivity and thermal conductivity, good corrosion resistance and weldability, and can be used as structural materials. It has a wide range of applications in aerospace, aviation, transportation, construction, electromechanical, light chemical and daily necessities.
