8 Piece Gemstone Aluminum Black Battery

Food-safe aluminum must be 99.5% pure.
Aluminum offers the best cooking quality and cost ratio. That’s because it is affordable and a good heat conductor (as long as the base is thick enough).
Aluminum is not very tough: it can be easily dented by just falling off the worktop. It may react to some foods which is why it is advisable to purchase the anodized version or make sure it has a non-stick coating.

Anodized aluminum is treated with an electrochemical process that increases its mechanical and corrosion resistance.
This material possesses excellent features that make it perfect for cooking: firstly, very high heat conductivity rated around 250 W/mK. Secondarily, it is intrinsically easy to varnish, making it suitable for preliminary treatments. It is also very resistant to corrosion. Lastly, it offers the great advantage of being suitable for two molding techniques: forging and die casting. The first molding method initially uses discs in diameters and thicknesses that depend on the item to be made. They are then pressed into a reverse mold by a forming punch. Die casting makes it possible to obtain more complex shapes because it uses molten metal. On the whole, this process is more complex.
