Components from Elmedur

Our Elmedur materials are particularly versatile. We produce parts from them according to drawings - and of course also individual parts. All according to your wishes and requirements.

Electrodes

No matter which electrodes you need: Among our large selection of standard electrodes you will find the right one for your purposes. We manufacture electrodes from hardenable copper materials, which are very hard and at the same time highly conductive. They are ideal for applications in which high electrical currents are transmitted under high mechanical loads.

Components made of high-melting metals

From our refractory metals molybdenum, TZM, tungsten and tantalum we manufacture parts according to drawings as well as individual parts. As the metals are very easy to process, they are ideal for a wide range of applications.

For a more sustainable future in construction.

With its 100 % share of recycled material, the cuprolife copper tube makes a sustainable difference, and thus makes a significant contribution to the advancement of building and construction as well as building services. 

Every cuprolife tube from Wieland is manufactured in keeping with the mass balance approach – using a process with 100 % recycled copper. As the starting point when verifying cuprolife, TÜV SÜD tested the procedure for calculating the 100 % recycled content*.

The new standard in copper tubes: cuprolife^®.

Thanks to cutting-edge manufacturing techniques, cuprolife tubes exceed even the highest requirements. Optimal efficiency and reliability are guaranteed along with an exceptional service life. cuprolife tubes are universally usable. cuprolife is permanently in stock and can be supplied in any size from 6 x 1 mm to 159 x 3 mm.

K65 - 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). 
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”.

All Wieland K65 tubes are available in the soft condition (R300/O61) to ensure excellent bending / flaring and collaring properties.

Other dimensions and delivery forms such as level wound coils are offered for industrial processing, in particular manufacturing of CO2 heat exchangers (evaporator/gas cooler).
