As a mechanical engineer, buyer or designer, you may be familiar with the confusion that comes with the various material numbering systems used in the EU and US. The material numbering system is essential for identifying and organizing raw materials used in manufacturing processes. In this blog post, we will focus on the aluminum material numbering system and the difference between the European Numbering System (ENS) and the Unified Numbering Systems (UNS) used in the EU and US, respectively. We will also list aluminum materials with their corresponding ENS and UNS numbers to help you better understand and navigate the aluminum material world.
European Numbering System (ENS)
The European Numbering System or ENS is used in the EU to identify and categorize raw materials. The ENS includes a four-digit number followed by a letter symbolizing the material type group. The first two digits represent the material type while the last two digits signify its alloy composition. For instance, 1050 aluminum corresponds to 1xxx group (un-alloyed aluminum series), 6061 aluminum corresponds to 6xxx group (aluminum-magnesium-silicon series) while 7075 aluminum corresponds to 7xxx group (aluminum-zinc-magnesium-copper series).
Unified Numbering System (UNS)
On the other hand, the Unified Numbering System or UNS is used in the US to identify raw materials. The UNS numbering system comprises a combination of letters and numbers representing material type and alloy content, respectively. For example, an aluminum material with UNS of A97075 is equivalent to aluminum material in the 7075 series. The UNS and ENS material numbering systems are quite similar, and the only difference lies in the letter symbolizing the material type group.
List of common aluminum materials with their corresponding ENS and UNS Numbers
Conclusion:
In conclusion, the aluminum material numbering system can be used to standardize the identification, and organization of aluminum materials. The ENS and UNS are the common numbering systems used in the EU and US, respectively, to classify raw materials such as aluminum. Understanding the material numbering system in your region is critical in sourcing and selecting raw materials that meet the intended design and manufacturing specifications. By providing you with a list of common aluminum materials and their corresponding ENS and UNS numbers, we hope to help you navigate the world of aluminum materials with more ease and confidence.
