The metal labial pipes are made of different tin-lead alloys. We match the alloys to the room acoustics according to the sound requirements.
Over the past 20 years, we have gained groundbreaking insights through the reconstruction of historical alloy compositions in cooperation with the University of Potsdam.
The alloy “English Tin” with a tin content of 96 percent was analyzed and reconstructed by us. This metal is very hard and shows excellent tonal properties, especially in the response behavior of the deep 16′ and 8′ registers, as well as a stability that prevents the pipe feet and bodies from sagging in the labia area.
In addition, there is a sustainable material saving of around 60 percent compared to the alloys previously used. From the casting of the metal plates to the pre-intoned pipes, we have created the possibility to produce everything in our own workshop.
Due to our 25 years of practical experience with this processing method, we give our customers a 25-year warranty for the stability of these pipes.
