Advantages of 1920 aluminum alloy
1920 aluminum alloy combines relatively high strength with relatively low density, making it suitable for industrial projects that require weight reduction, load-bearing capacity, and processing adaptability. Its main advantages include:
- High strength and light weight, suitable for projects that require both weight reduction and load-bearing capacity.

- Good welding and processing performance, making it convenient for extrusion, forming, and subsequent structural processing.
- Suitable for manufacturing complex profiles and able to meet various cross-sectional and structural design requirements.
- Stable overall performance, suitable for long-term applications that require material reliability.
- Good electrical conductivity and processing adaptability, suitable for various industrial components and functional parts.
Limitations of 1920 aluminum alloy
- Limited heat resistance. It is generally not recommended for long-term use in working conditions above 150°C.
- Processing must be properly controlled. Otherwise, the risk of intergranular corrosion may increase.
- There are few international equivalent grades, so material conversion can be more difficult in some export or substitution projects.
Similar grades in other countries and guidance on alternative material selection
1920 aluminum alloy (B92 / В92) does not have a widely recognized one-to-one equivalent grade in commonly used international standard systems such as ISO, EN, and ASTM.
1920 belongs to the Al-Zn-Mg high-strength wrought aluminum alloy series, core standard based on OST 1-92014-90.
Material substitution usually cannot be made directly based only on the grade name.
Points to check carefully:
- Whether the chemical composition is close.
- Whether the mechanical properties meet the application requirements.
- Whether the supply condition and heat treatment condition are consistent.
- Whether corrosion resistance, weldability, and processing adaptability match.
- Whether the applicable standards, certification system, and actual application scenario allow substitution.
For projects that require international standard conversion or approximate material selection, it is recommended to carry out a comprehensive evaluation based on composition, properties, condition, and specific application in order to select an alternative material that is closer to the project requirements.
