I have some the anodized Calphalon, and I know that if I scratch it with stainless steel utensils, the scrape is shiny aluminum.
Don't store the tomatoes in the pan--you will have pitting--but I wouldn't worry a minute about cooking in it. There is an urban legend that aluminum causes Alzheimers, but that has been disproven.
I don't know about having a claim against them.
I just haven't been the same
since that house fell on my sister.
