W5000 precision brass rods
The Wieland WICONNEC brand offers a range of copper materials in the form of rods and wires that are ideal for machined sockets and pins for plug connectors. This material portfolio also offers brass materials in addition to specially developed copper alloys for complex turned plug connectors.
Materials
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.

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.
