ecoline: lead-free solutions for a sustainable future
Specialized. Reliable. Ecological.
Wieland ecoline is our answer to enable your future business: the lead-free product line fulfills your individual needs for an efficient production and future oriented product development. And is, of course, compliant with the latest requirements of legislative directives on lead-free materials.
For many years we have been researching how we can provide machinability and formability as well as electrical and thermal conductivity, relaxation and corrosion resistance in alloys with less and less lead. Today, we have proven answers to this and provide the market with a number of different alloys: optimized specifically to the requirements of different applications, like automotive, drinking water applications, electrical components and high-value accessories. We understand each application has a special need - and we care, for making your business run while being responsible and responsive. Also, we are your partner to understand and interpret legislative requirements concerning lead-free materials.
3 compelling reasons for ecoline
- specialized. Find your solution partner who considers the best processes and understands your needs.
- reliable. Count on flexible supply and best services - with a stable quality level of high-grade alloys.
- ecological. Do not only be compliant with standards but responsively shape the future.
ecoline. applications.
4 applications of ecoline cover a broad portfolio and highest requirements on machinability and formability – compliant with the most important regulations and legislative directives.
ecoline water
High requirements on processability, corrosion resistance and hygiene. For all tubes, joints and components in contact with drinking water.
ecoline connect
Outstanding properties - machinable, cold formable and conductive. For all current and signal-carrying components.
ecoline drive
A wide range of solutions for every requirement and various components: drive train components, hot pressed parts and turned parts.
ecoline accessories
The lowest possible lead content is particularly important for goods in daily use.
ecoline. properties.
Each application needs components with different characteristics - from abrasion resistance to conductivity and temperature resistance as well as machining properties. We optimized our ecoline portfolio to four basic applications. Find here the exact specifications - and please, get in touch with us for more.
ecoline water
Drinking water is our most important food. The quality of drinking water must be of such a high standard that it can be enjoyed without restriction throughout life. For this reason, ever stricter requirements are being imposed worldwide on materials that come into contact with drinking water. The appropriate selection of materials and products for drinking water installations is therefore extremely important. Technical, economic, but especially hygienic and health aspects play a major role.
Copper alloys have proven themselves technically and hygienically billions of times worldwide in drinking water installations and will therefore continue to be the basis for clean drinking water in the future.

ecoline connect
For sockets and pins for connectors and other electrical components, we provide rods, wires and profiles, made of the copper alloys with the most suitable characteristics. In addition to low-cost brass materials, the materials portfolio includes specially developed copper materials for demanding applications of turned connectors.
Depending on the technical requirements, materials with high electrical conductivity or high mechanical strengths as well as a combination of both of these properties will be applied.
