High mechanical strength
Its grain refiner ensures an extremely fine grain size, facilitating even distribution of force throughout the entire structure. The result: strength and hardness otherwise only known in steel, even with thin, weight-reducing wall thicknesses.
Improved casting
Thanks to its fine-grained structure, Ecocast is ideal for filigree components.
Reduced waste
In every situation where you were previously dependent on red brass for filigree shapes, the high amount of waste of this conventional material is eliminated with Ecocast.
Excellent machinability
Ecocast and its special chemical composition also makes reworking cast parts through machining, grinding, polishing, or coating safe, precise, and cost-effective.
Top-rate corrosion resistance
The fine-grained structure through and through also means minimal dezincification on the surface due to touching, oxidation, or cleaning.
The future is lead-free
Secure your market lead: with Ecocast you can design and equip your products for the future, too. After all, many countries and various customers are already implementing strict regulations concerning the use of lead-free materials.
Universal
Ecocast can be cast both in ingot molds and in sand. The material is standardized under CC768S in EN 1982.
Ecocast: The New Material for Sanitary Installations
Ecocast is the perfect material for sanitary installations, not just for meeting drinking water regulations in the future, but also mainly for meeting current cost-efficiency requirements. Thanks to its high mechanical strength, Ecocast achieves wall thicknesses that help significantly reduce weight and save on materials and costs without compromising on stability. Moreover, Ecocast can handle forces (or moments) that until now have only been reserved for steel. The fine-grained structure and lack of lead produce surfaces that are aesthetically impeccable when Ecocast parts are coated.
Functional Properties, Long-Lasting Look
The extremely corrosion-resistant brass material Ecocast has a premium golden surface that is especially long -lasting, making it suitable even for frequently used objects and room fixtures made from cast parts. Ecocast also has high color stability and resistance to degradation caused by contact, air humidity, or intensive cleaning, which increases hygiene safety in hospitals, clinics, and nursing care institutions. - The innovative cast material from Wieland retains its functional properties even with heavy day-to-day use.
Ingots produced by continuous casting are superior to classical ingots. This can be seen at many steps of further processing.
We can now also offer these as standard for aluminium bronzes.
Aluminium bronze properties
Higher output
Solidification of the ingots in the cooler without contact with oxygen prevents oxide formation and gas inclusions in the ingots. This significantly reduces the amount of dross in further processing.
Reduced scrap
The purer the base material used in the casting process, the lower the reject rate due to foreign bodies or oxide inclusions.
Thin casting skin
Thinner casting skins are formed during further processing into semi-finished products or components. Casting close to final dimensions and reduced machining oversizes are possible. This reduces machining times and saves production costs.
Uniform material properties
Continuously cast ingots minimize foreign inclusions and inhomogeneities in the component. The mechanical properties are more uniform.
Our continuous cast ingots save costs where the end products take shape - in your production!

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.
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.
Here you will find detailed information on ecoline water – please contact us if you have any questions.
All current Guidelines for lead-free materials are summarised in the Regulations.

K65 - Sustainable and efficient
Sustainable and efficient – two keywords that have had a decisive impact on our time and have gained in relevance in recent years, especially in refrigeration. Increased environmental awareness in society and industry has therefore led to a kind of renaissance of natural refrigerants, especially CO2. Wieland supports this turnaround with a tube system that meets the high requirements of CO2 as a refrigerant.
Wieland K65 tubes have been designed for CO2 applications in the commercial field, especially that of supermarket refrigeration systems. Wieland K65 alloy provides the mechanical strength high enough to withstand the high operating pressures of CO2. At the same time, K65 tubes have outstanding processing properties, similar to those of standard copper (Cu-DHP/C12200).
All Wieland K65 tubes are available in the soft condition (R300/O61) to ensure excellent bending / flaring and collaring properties.
Wieland K65 tubes are offered from stock in two pressure ranges, 80 bar and 120 bar, and in dimensions ranging from 3/8” up to 2-1/8”.
Moreover, K65 tubes are also available in individual dimensions and different delivery forms.
For industrial processing, in particular CO2 heat exchanger (evaporator / gas cooler) manufacturing, level wound coils (LWC) are offered.

In electrical and electronic applications, contact resistance plays a crucial role. The formation of oxide layers can compromise this severely and may cause contact failure. As a rule, therefore, at least the contact zones are coated. The most common coatings are of tin or tin alloys. Our products are treated on ultra modern hot dip tinning plant. A range of tin plated variants are possible, depending on the customer’s requirements.
We can also offer strips with full or selective silver or nickel plating. These strips you can purchase directly from us as a single source. They are finished at external partner companies.
