Important results from the project
A solution that meets all requirements from the various parts along the value chain, focusing on corrosion, casting, and processing, has not been identified. However, promising concepts exist beyond the individual alloys listed on the first EU positive list for materials in contact with drinking water. Active and innovative work on the entire machining process has contributed to new solutions to challenges that previously could only be solved with more powerful and flexible machines.
Expected long term effects
The perception among project partners is that they are well-prepared compared to others within the EU and globally. This is based on having an updated understanding of the new requirements and being technically advanced in addressing the challenges generally associated with lead-free brass. The partners belivies that transition to lead-free brass is completed by the end of the transition period in 2032. However, there is some uncertainty regarding the economy, circularity, and climate impact.
Approach and implementation
9 different companies along the brass value chain and 2 research institutes formed the consortium. Lab tests were alternated with industrial trials. E.g. casting trials were conducted at one partner´s facility with participants from others. Studies of microstructure, defects, and corrosion were performed. Discussions on approaches to address challenges in processing were conducted openly and mutually, and partners reported saving months compared to if all parts had been carried out individually
