We are essential. And remain modest at the same time. 

From telephone lines in the 19th century to ultra-modern components for aerospace and medical technology today: our products have been an elementary part of countless value chains since our foundation - and although we usually remain in the background, many things would stand still without us. We are aware of this relevance and accept it as our deep responsibility. It is our incentive to constantly reinvent ourselves and deliver sustainable solutions that move us and our customers forward.

We are sovereign. And therefore reliable.

We act with calm and clarity, even when the world around us is turbulent. Our +200-year history has taught us to face challenges with integrity and foresight. This self-confidence is the basis for our actions - as a reliable partner who knows about their strengths and remains open to new ideas. Our confident attitude extends security and orientation to our customers, no matter how complex the task.

3

We are highly experienced. And set standards.

Our expertise is the foundation on which we combine innovation and precision. We understand our customers' challenges down to the last detail and have the knowledge and skills to create excellent solutions. This technological and technical expertise drives us to shape markets and set standards. For us, it is a matter of course to demonstrate our skills every day - visible in every product, every partnership, every step.

Our basic conviction

We believe that economic success, human interaction, credibility and optimism are not a contradiction in terms - but rather the basis for sustainable action and healthy, stable growth.
