Key benefits at a glance

Our crucibles are made from refractory metals and alloys such as molybdenum, tungsten, tantalum or rhenium. They are designed for the highest thermal loads and guarantee even heat distribution, excellent corrosion resistance and a long service life. Thanks to precise manufacturing and certified materials, we offer solutions for laboratory, industrial and high-performance applications.
High temperature resistance
Stable up to over 3,000 °C - ideal for melting, evaporation and crystal growing processes.
Excellent material purity
Our crucibles are made of metals with purities of up to ≥ 99.95 % and ensure contamination-free melting.
Made to measure according to specification
Whether cylindrical, conical or complex in shape - we manufacture crucibles exactly according to drawings or samples.

Technical properties

Our crucibles are available in different geometries, wall thicknesses and materials. They are manufactured using precise forming, turning or deep-drawing processes and are suitable for vacuum, induction or resistance heating systems. On request, we can supply variants with lids, drains, holes or adapted rims – including material certificate and traceability.
