Aluminum foil or rolls in specific alloys and tempers, with thickness ranges adequate for fin manufacturing for heat exchanger applications. This fin stock will have a thickness of less or equal to 0.800 mm or greater than 0.060 mm.

Typical Applications

Automotive applications. Heat exchangers and radiator fins.

Standard Format

Rolls and strips

Applicable Standards
Aluminum Standards and Data,
The Aluminum Association.

ASTM B-479

 

Relevant Characteristics

• High resistance to corrosion.
• Good ductility.
• Good thermal conductivity.

All tolerances conform to Standard AA. However, the plant is able to provide narrower tolerances in some cases (including 1/2 ASTM or AA), previous verification of orders.
