不是铝, 是氧化铝,其坚硬程度相当高,而且和大多数酸碱都不翻译。不信你到实验室里去看,盛硝酸的瓶子都是铝的,就是因为上面有氧化铝保护膜。
各位可以放狗搜一下,hard anodized cookware safety。

, I knew already anodized aluminum is different from aluminum before i made my previous comment
From internet:
Anodized Aluminum Cookware Manufacturers and industry lobbyists all claim it is safe. Their biggest argument is that the amount of aluminum leached from hard anodized aluminum cookware is a mere 35 micrograms. That is a small amount. By itself, as a single dose, it is not harmful. Therefore, my recommendation is this:
If you are not concerned with aluminum toxicity, or use anodized aluminum cookware with other cookware materials, anodized aluminum cookware is fine to use. However, if part of your normal health routine is to minimize your exposure to metals, or you sometimes do a heavy metal detox diet, I recommend avoiding hard anodized aluminum cookware. The issue is not about the small single dose. It is about the cumulative effect it can have. Just like eating a single chocolate bar is not going to cause a serious disease. However, 3-6 chocolate bars a day every day, will have an impact on your body. If most meals are cooked with anodized aluminum frypans, saute pans, sauce pans, and stockpots, the cumulative effect, along with the aluminum you already get from other items in our environment, may cause a health issue.
My thinking is: adults will probably die earlier than to be poisoned by it, kids still have a very long life to go
