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!
Optimized processing of scrap into high-quality ingot materials is ensured by well-qualified employees and state-of-the-art system technology, from ball mills and drum melting furnaces to continuous cast systems.
As a certified company, we manufacture the majority of our products in accordance with special customer requirements and the DIN EN 1982:2017 standard.
Certifications:
- DIN EN ISO 9001:2015
- DIN EN ISO 14001:2015

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.

W5000 precision brass rods
The closer the input stock approaches the end product, the higher the efficiency of downstream machining. The Wieland E5006 precision hexagon rod fulfils these expectations in a quite special way: It presents the precise outer contours of a workpiece. Unlike machined multiedge cross sections, drawn edged rods are characterised by extremely smooth, plane, and compacted surfaces. Moreover, they lend the workpiece a continuous grain structure of high impact toughness. Obvious material savings are yet another benefit.

Wieland recognized the potential of environmentally friendly, lead-free machining brass at a very early date, and adopted the pioneering role in Europe by developing ECOBRASS. This proved to be a farsighted course into the future. Today, ECOBRASS is marketed worldwide over a cooperation network and available, even in smaller quantities, from trade partners. We also market this material under the name “CUPHIN” for sanitary products.

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.

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.

From Europe’s largest copper alloy foundry in Vöhringen/Iller (Germany), we can offer you far in excess of a hundred different copper materials. These include not only a wide range of continuous castings like tubes and rods, but also shaped rods and sections of complex geometries. At the same time, our flexibility ensures the prompt realisation of your special custom wishes.
Materials

Wieland hot stamping rods
Good forging results can be obtained only when all links in the process chain have been matched to each other to the optimal effect. With Wieland hot stamping rods you are offered a forging stock which comprehensively fulfils these requirements. Your benefits: uniform dark surface for reproducible processing properties, tight diameter tolerances in the drawn size range, and hence precise configuration of the slug weight.
