1100/1200/3003 DC/CC Aluminium Circle for cookware/speaker
Signi supplies aluminium disc in a wide variety of sizes and alloys. Two state of the art disc blanking presses combined with open shear processing enable our facilities to supply a diverse range of markets. Aluminium circles are specialized products that are mostly used in the production of cookware,trafficsignals, gas containers, automobile brakes and antennae. Our metallurgical processes ensure availability of deep drawing quality specifications that match these demanding applications.
The properties of aluminum disc (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.
