Cold Rolled Aluminum Sheet Circle

Quick Detal:

1. Low anisotropy, which facilitates deep drawing
2. Strong mechanical properties
3. High and homogeneous heat diffusion
4. Ability to be enameled, covered by PTFE (or others), anodized

Description:

Commercially pure aluminum (1000-series aluminum, which is 99.9%+ pure) has the highest of thermal conductivity all aluminum alloys, but due to the “orange peel effect” where bonded pure aluminum can form bumps and ridges similar to orange peels due to the nature of its grain, it is not viable to use ONLY pure aluminum as the core of a cladded material (few customers would accept bumpy-looking cookware).  Thus, typically you will see a construction like so: stainless steel, a very thin bonding layer of pure aluminum, a core of 3003 or 3004 aluminum, a very thin bonding layer of pure aluminum, and stainless steel. 3003/3004 aluminum has significantly lower thermal conductivity than pure aluminum, but you also avoid the orange peel effect.

If you are wondering why cookware manufacturers use 3003/3004 aluminum instead of some other aluminum alloys that have slightly higher thermal conductivity, it is because 3003/3004 aluminum is inexpensive, is easily formed (i.e., made into different shapes and sizes of cookware), has durability/strength good enough for kitchen cooking, and is more corrosion-resistant than many other aluminum alloys. That last factor is very important, since commercial and residential cookware is continually being banged into drawers/sinks/stovetops and being left with water, saltwater, and acids in them at all sorts of temperatures.

Aluminum circles is widely used in electronics, comestic, medicine, auto parts, home appliances, machine manfacturing, moulding, building and printing, especially for cookware, like non-stick pan, pressure cooker, and hardware, like lampshade, jacketing shall. Aluminum circle disc is the most widely used deep drawing products of aluminum alloy strip.
