Why did my Zwilling Aluminium pan cookware surface corrode just after 1 month?

Seasoned Advice Asked by arab on May 23, 2021

On March 3 2021, I bought this Zwilling 33 cm / 13 inch Aluminium deep saute pan with lid. Please review pictures below, inside my red circle. The coating on the surface appears to have corroded! Why? What went wrong?

I was careful not to scratch or corrode the coating! I used sponges to clean. I used plastic heat resistant Turners.

This is not corrosion, this is damage to the non-stick surface.

Overheating the pan can damage non-stick coatings. As these marks are in the centre of the pan I suspect that there are two possibilities:

  1. The pan was heated too hot and damaged the coating
  2. The "corrosion" is actually damage to a layer of polymerized oils/fats analogous to seasoning on a cast-iron pan.
