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:
Low anisotropy, which facilitates deep drawing
Strong mechanical properties
High and homogeneous heat diffusion
Ability to be enameled, covered by PTFE (or others), anodized
Good reflectivity
High strength-to-weight ratio
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.
