3104 aluminum is a member of the 3000 series aluminum alloys, with manganese as its primary alloying element. It has the lowest electrical conductivity in the 3000 series and is commonly used for primary forming and forging products.
Aluminum Alloy Series
Series: 3000 series
Main Alloying Element
3104 aluminum is a 3000 series aluminum alloy, the main alloy additive is manganese, and the strength is higher than the 1000 series. 3104 alloy aluminum plate has good deep drawing performance and is suitable for thinning and stretching to reduce the amount of lightweight materials.
3104 aluminum adds other trace elements to give it better elongation, corrosion resistance, and processing performance. It can be processed into different states with different hardness.
3104 aluminum plate is an alloy that cannot be heat-treated. Its strength is slightly stronger than the 1 series pure aluminum used in industry, so cold processing is required to improve its mechanical properties. The elongation of the aluminum plate can reach 20%.
