“The turret is of aluminum alloy armor construction. ”I was quite shocked when I saw this paragraph.
A lot of news is currently highlighting the similarity of the turret to the Abrams tank,but they don't even mention that it's aluminum armor.
I haven't paid attention to MPF, so I'm surprised to know this.Now I can understand why the U.S. Army is unwilling to call MPF a tank.
In the discussion on Zhihu, many people ridiculed that Americans should use design schemes based on T-55 or T-64.
From what I found about aluminium alloy armor:
"Crystallized aluminum oxide, better known as corundum, is a surprisingly feasible armor choice. It's extremely strong, the definition of a 9/10 on the Mohs scale. Normal steel has a hardness of 4-4.5 and hardened steel has a hardness of 7.5-8. What this means is that a steel blade, even a tempered one, wouldn't scratch the armor. In fact, the armor would be more likely to scratch it!"
