Hard Anodized Nonstick

Advantages of Hard anodized Aluminum


Anodized aluminum is lighter weight
and non conductivity. Anodize means
that aluminum is immersed in sulfuric
acid known as electrolyte. Then it runs
through a low voltage electric current
through the acid solution. When the
electric current increases significantly
and the acid solution is freezed it is
called as hard anodizing. Hard
anodized aluminum is 30% harder than
stainless steel. They have a extremely
long life span. Its surfaces do not chip
or peel and non toxic. It is chemically
stable and does not decompose. Even in high heat level the anodized finish will not be damaged
because it has a melting point of 1,221degree F.

Hard anodizing is mostly used for industrial purposes. Non stick coating is processed through
regular anodized aluminum but aluminum cookware is processed through hard anodized
aluminum. Hard anodizing aluminum has a thick coating than regular anodize.
Aluminum sheets passing through hard anodizing has a dark brown or black surface. The benefits
of hard anodizing are it has lower cost and weight. The aluminum cookware would resist harsh
climate and salt sprays because it is processed through hard aluminum. Automobile industry and
commercial cookware have benefited from hard anodizing. Even automobile parts have benefited
from it. It has also benefited the medical field. In prosthetic joints also hard anodizing aluminum is
used because it can resist blood. Hard anodizing and sulfuric anodizing may have certain things in
common but their process will give a different result. The hard anodize is little more expensive
than regular anodized aluminum.


While buying a new aluminum cookware see whether it is a anodized aluminum or hard anodized.
The surfaces are stick resistant. Aluminum is present in many products like in cookware and
utensils, baking powder, toothpastes, sunscreens, cosmetics, vaccines, cake mix and in many
more things. Anodized aluminum is used in grills, coolers etc. The cookware surface does not
have pores because it has a hard anodize finish. If there are pores in the cookware the food gets
stuck while cooking but if it does not have pores the food does not stick. Black is the most famous
color in anodizing. This color gets the highest price. Other colors can be easily achieved. These
colors are also used in different aluminum utensils. Anodizing can be done at home also with the
help of sulfuric acid.
