The properties of aluminum circles (or shaped blanks) make them ideal for use in a number of markets including the cookware, automotive and lighting industries:
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
5. Good reflectivity
6. High strength-to-weight ratio
7. Durability and resistance to corrosion
Signi aluminum offers circles and shaped blanks in a wide range of alloys, tempers, thicknesses and diameters to meet all likely customer requirements.
