Strong metals. Strong products.
Whether in modern flat screens, energy-saving LEDs or environmentally responsible fuel
cells, whenever conventional materials come up against their limits, molybdenum,
tungsten, tantalum, niobium and chromium take over.
What makes our metals so special?
Tungsten, tantalum and molybdenum are the metals with the greatest heat resistance. Whereas iron and steels start to feel the heat even at 1 600 degrees Celsius, these temperatures leave our materials cold. With their high melting point, they are suitable for use as heaters in high-temperature furnaces or as incandescent filaments in lamps. In electrical switch contacts, they are valuable because of their excellent electrical and thermal conductivity. As electrically conductive film in flat screens and solar cells, our alloys are remarkable for their low coefficient of thermal expansion. In this way, they bring astonishingly sharp image quality to our living rooms and provide us with clean energy.
From the raw material to the finished product.
We use powder metallurgical methods to manufacture our refractory metals and composite materials. To make sure that nothing is left to chance, we start at the very beginning: with the raw material taken directly from the mine. We reduce this to form pure metal powder. We then press and sinter this. With the world's largest hot rolling mill for refractory metals, we form our metals to produce exceptionally rugged materials.
