Family: Aluminum Alloy
Manganese Alloy (Al-Mn). AA designation 3003.
Overview
The most widely used of the aluminium–manganese alloys, AA 3003 carries 1.0–1.5% manganese that lifts strength modestly above pure aluminium while preserving excellent corrosion resistance and workability. Non-heat-treatable, it responds well to cold working and forms readily into complex shapes. That balance of formability and durability suits cooking utensils, heat exchangers, chemical equipment, building products, and food packaging.

Description
AA 3003 is the most widely used aluminum-manganese alloy, containing 1.0–1.5% manganese that provides moderate strength improvement over pure aluminum while retaining excellent corrosion resistance and workability. It is non-heat-treatable but responds well to cold working, and offers outstanding formability for complex shapes. Common applications include cooking utensils, heat exchangers, chemical equipment, building products, and food packaging.
