In the mechanical and metalworking industry, choosing the right grade of aluminum (aluminum alloy) for each application is a decisive factor in performance, durability and production costs. However, in many cases, some aluminum product codes can be interchangeable while still ensuring technical requirements and product quality.
1. Aluminum group commonly used in mechanical processing
The most popular aluminum grades today include: A1050, A1100, A3003, A5052, A6061, A6063 , and A7075 . Each type has its own characteristics:
- A1050 / A1100: High purity aluminum, soft, ductile, suitable for decorative details, electrical and thermal conductivity.
- A3003: With added manganese, increases strength and corrosion resistance, suitable for making plates, pipes, tanks.
- A5052: More durable, resistant to marine environments, often used for equipment housings, automotive and marine parts.
- A6061 / A6063: Easy to machine, easy to weld, heat treatable, widely used in precision mechanics, aluminum structures.
- A7075: High-grade aluminum alloy, super durable, used in aviation, molds, and high-load components.
2. The aluminum code pairs can be replaced with equivalent ones.
| Original aluminum code |
Equivalent replacement code |
Note |
| A1050 ↔ A1100 |
Can be replaced directly |
Nearly equivalent in purity, conductivity |
| A3003 ↔ A5052 |
Can be replaced in products requiring corrosion resistance |
A5052 is more durable, suitable for harsh environments |
| A6061 ↔ A6063 |
Can be used as a substitute for aluminum structures, frames, and tubes. |
A6061 is harder, A6063 has a more beautiful surface |
| A7075 ↔ A6061 |
Can be replaced depending on load bearing requirements |
A7075 is stronger, A6061 is more economical |
When selecting an alternative aluminum code, it is necessary to consider the working environment, processing method, mechanical requirements and cost to ensure both technical and economic optimization.
