Ecobrass, also known as lead-free brass, is an environmentally friendly alternative to traditional brass alloys that typically contain lead. It is designed to meet stringent environmental and health regulations, particularly those concerning lead content in materials that come into contact with drinking water and food.

Key Characteristics of Ecobrass


Ecobrass usually consists of a mix of copper (Cu), zinc (Zn), and silicon (Si). The silicon is used as a replacement for lead to improve machinability and corrosion resistance.


  • Corrosion Resistance: Ecobrass exhibits excellent resistance to dezincification and stress corrosion cracking, making it suitable for plumbing applications.
  • Machinability: The inclusion of silicon improves machinability, which is essential for manufacturing precision components.
  • Mechanical Strength: It retains good mechanical properties, including tensile and yield strength, similar to traditional leaded brass.
  • Thermal Conductivity: While slightly lower than traditional brass, Ecobrass still offers adequate thermal conductivity for many applications.


  • Plumbing and Water Fittings: Due to its compliance with drinking water regulations, it's widely used in valves, faucets, and other plumbing fixtures.
  • Automotive Components: Used in various automotive parts due to its durability and machinability.
  • Electrical and Electronic Components: Employed in connectors and terminals for its excellent conductivity and corrosion resistance.
  • Medical Devices: Utilized in certain medical applications where biocompatibility and compliance with health standards are critical.

Environmental and Health Benefits

  • Lead-Free: Eliminates the health risks associated with lead exposure, making it safer for use in products that come into contact with humans.
  • Recyclability: Ecobrass can be recycled efficiently, contributing to reduced environmental impact.
  • Compliance: Meets global regulations such as the EU's RoHS (Restriction of Hazardous Substances) directive and the U.S. Safe Drinking Water Act, which limits lead content in materials.

Manufacturing and Market Considerations

Manufacturers adopting Ecobrass benefit from aligning with regulatory requirements and consumer preferences for safer, greener products. However, the shift to Ecobrass might involve higher initial material costs and adjustments in machining processes to accommodate the different properties compared to traditional brass. Despite these challenges, the long-term benefits in terms of regulatory compliance and market acceptance often outweigh the drawbacks.
