On its upcasters, Lamifil produces a series of copper alloys. Some of these are used as special fine wire for high tech wires in aerospace, electronics and automotive, where high strength and good conductivity have to be combined with excellent flexlife.
Depending on whether strength or electrical conductivity is the most important, the appropriate alloy will be chosen. For one alloy, we can offer different quality ranges, thus offering a tailor-made solution for the customer’s requirements.
As you may expect from Lamifil, we continue to innovate and expand our product lines. That is why we are focusing our research both on new copper alloys and on optimisation of their characteristics.
CuMg
Copper magnesium was developed as an environmental friendly alternative to copper cadmium. The CuMg alloy can resist high tensions, on the other hand losing a bit in conductivity compared to CuCd. Lamifil can offer various subqualities of CuMg alloy, thus finding the most appropriate solution for each application.
CuCd
For certain applications copper cadmium is required because of its superior characteristics. CuCd combines high strength with good conductivity. The alloy has unsurpassed flex life, it is therefore used for certain, critical applications.
CuSn
Where the strength of CuMg is not required, copper tin may be an alternative. CuSn is relatively workable and has a good conductivity.
Cu – CuAg
For applications where the conductivity is of prime importance, electrolytic copper and copper silver are widely used. CuAg has virtually the same electrical and mechanical characteristics as ETP copper. The benefit is a better thermal stability, which is due to the higher recrystalisation temperature.
CuP
This alloy is used in special fine wire applications.
