Primary aluminum ingots are used to create aluminum semi-fabricated products, such as rolled coils, casted components, or extrusions for further aluminum product manufacturing.
- Aluminum products are often made from both primary and recycled ingots
- There is no relevant chemical composition difference between primary and secondary ingots if both are governed by the same alloy designation and chemical composition limit standards
- The service life of the final product depends on its application, but is typically long due to aluminum’s excellent corrosion resistance
- For that same reason, maintenance needs during use are usually low.
