Improved lead-free brass products by optimization along the value chain (OptiBrass)

Reference number
Coordinator RISE KIMAB AB - RISE KIMAB
Funding from Vinnova SEK 5 000 000
Project duration October 2019 - April 2022
Status Ongoing
Venture The strategic innovation programme for Metallic material
Call Metallic materials - high and secured product performance in a value chain perspective

Purpose and goal

Brass is traditionally alloys with lead to improve machinability and casting. However, due to health and environmental hazards, lead is foresight to be banned within the coming decade. Implementation of existing lead-free alloys is very limited due to higher material cost, casting problems and poor machinability. The goal of the project is not only to reduce the lead content in brass in order to meet or exceed current and future regulations, but even to achieve this with increased properties of the final product with minimal environmental and economic impact.

Expected results and effects

As a result of the project, high performance cost-efficient products and components based on lead-free brass will be introduced to the market in a competitive way through the whole value chain. This will allow for a successful transition to lead-free material, giving the Swedish brass industry prospects for growth and international technological leadership. The lead-free brass products will become a main alternative for a conventional material selection and thus replace the conventional leaded brass.

Planned approach and implementation

The project is a collaboration between three research organizations and ten companies and within three work packages. The companies cover the entire value chain of the brass industry. How the different steps of the value chain are correlated to each other and influence the final properties of the products will be clearly defined in the initial work. Adapted tools will be put together and further developed to efficiently determine the optimal alloying and processing parameters needed to obtain desired product properties. Based on these, extensive industrial trials will be done.
