Aluminum alloy circle
Aluminum circles, also known as billets or discs, are widely used in making cookware such as pots, plates and cutlery due to their excellent thermal conductivity, light weight and corrosion resistance. The choice of aluminum alloy for kitchen aluminum circles depends on the specific requirements of the cookware, such as strength, machinability, thermal properties and surface finish.
Aluminum alloys for kitchen aluminum circle
Kitchen aluminum circles are mainly used to make cookware, cutlery, and other kitchenware because aluminum alloys have excellent thermal conductivity, chống ăn mòn, and formability. Among the 1000-8000 loạt hợp kim nhôm, which are the alloy grades that can be used for kitchen circles.

1XXX Series Aluminum Alloys
Alloy Grade: 1050, 1060, 1070, 1100
Composition: These alloys are almost pure aluminum (99% or more).
Features: Excellent corrosion resistance, excellent thermal conductivity, high ductility and excellent formability, making it easy to deep draw or spin into various cookware shapes. Lower strength compared to other series.
Application:
Best suited for lightweight cookware such as frying pans, stew pots and baking pans. Often used in anodized or coated cookware to improve surface durability.
3XXX Series Aluminum Alloys
Alloy Grade: 3003, 3105
Composition: 3000 series is mainly aluminum, with manganese (1-1.5%) as the main alloying element.
Features: Good corrosion resistance, especially to water and acidic environments, medium strength, with excellent formability. Improved hardness and scratch resistance compared to 1XXX series. Better mechanical properties at the same time, making it suitable for thicker or stronger cookware.
Applications:
Ideal for cookware that requires higher strength and deformation resistance, such as pressure cookers, heavy pots and pans. Often used for laminating or cladding cookware for enhanced durability.
5XXX Series Aluminum Alloys
Alloy Grade: 5052, 5005
Composition: Aluminum alloy alloyed with magnesium (2–5%).
Features:
5000 series aluminum alloy has excellent corrosion resistance, especially in marine or humid environments. Higher strength compared to 1XXX and 3XXX series. Good machinability, although slightly less ductile than 1XXX and 3XXX series. Excellent anodizing properties for an aesthetically pleasing finish and greater surface durability.
Applications:
For premium cookware requiring greater durability and strength.
For multi-layer or composite cookware with an aluminum-clad stainless steel core.
6XXX Series Aluminum Alloys
Alloy Grade: 6061
Composition: Aluminum alloy with magnesium and silicon.
Features: High strength and corrosion resistance, Not as ductile as 1XXX, 3XXX or 5XXX series, so not very suitable for deep drawing or spinning, Excellent machinability and weldability.
Applications: Occasionally used for specialty cookware requiring machinability or structural strength, such as heavy grills or lids.
What alloy is better for machining aluminum circles?
Alloys in the 1000 loạt và 3000 series are preferred for cookware due to their high ductility and ease of spinning, stamping or drawing into complex shapes. Both the 1000 loạt và 3000 series offer excellent corrosion resistance, trong khi 5000 series is better suited for harsher environments. For cookware that needs to withstand deformation or high loads, các 3000 loạt và 5000 series are more suitable than the 1XXX series.
Characteristics of aluminum alloy discs
For most kitchen aluminum discs:
1XXX series (1050, 1060, 1100): Best for lightweight, highly conductive cookware such as frying pans and baking pans.
3XXX series (3003, 3105): Great for more rugged cookware such as heavy pots and pressure cookers.
5XXX series (5052, 5005): Great for premium cookware that requires durability and enhanced surface properties.
Each alloy has its advantages, and the final choice depends on balancing cost, performance, and the characteristics required for the cookware.
