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.

Surface quality

Free from scratches, pit marks, rolling bands

Applicable standards

ASTM - B - 209M, Aluminium association _ aluminium standards and data, Hindalco manufacturing limits (as applicable).

Packing

The circles are packed in boxes or pallets with interleave paper, polythene, foam / thermocol. Pallets and boxes are strapped with hoop iron and clips. Silica gel packets are placed in the boxes for moisture protection.
