Research presentation 2008/03/18

 

In our presentation, we introduced the fact that we have developed equipment and technology that allows for molten metal rolling of an alloy (AZ61 alloy) that has excellent corrosion resistance and strength, and in order to emphasize its practicality, we also introduced the fact that we have been able to press, nickel-plate, and weld samples of AZ61 magnesium alloy plate manufactured by our company outside the company. These products were actually brought to the venue, and visitors were able to see that it was confirmed that our plate materials could be processed without any problems.

 

In addition, when we listened to presentations by other magnesium molten metal rolling manufacturers, all of them, including our company, cited three key points for future development in magnesium sheet manufacturing: "workability," "corrosion resistance," and "cost." However, we could sense the unique characteristics of each company in the path they took to reach these points.

 

Until now, the only wrought material that had been mentioned was AZ31, but this lecture also included several reports on AZ61, which was a boost to our research, which specializes in AZ61 alloy. According to the reports, AZ61 alloy has many advantages in addition to those that have been mentioned so far, such as its crystal structure remaining stable even when the material is heated during pressing compared to AZ31 alloy.

 

Other lectures mentioned the possibility of room temperature pressing of magnesium, which was previously thought to be impossible, and it became clear that there are still many unexplored areas of magnesium. Based on this, I would like to continue working hard on future developments without being bound by conventional wisdom.

 

Summary of this seminar

 

AZ61 alloy is better than AZ31
　-High strength.
　-Good corrosion resistance.
　- The crystal structure does not easily enlarge even at high temperatures.
