Sialon Ceramics presents a new generation of advanced Sialon extrusion and drawing dies – a superior class of technical ceramics that outperforms traditional silicon nitride (Si₃N₄). These high-precision dies are specially engineered for the extrusion and drawing of non-ferrous alloys such as copper, brass, and similar metals in the metal extrusion industry.
The revolutionary ultrasonic extrusion dies technology, when paired with our Sialon ULTRA™ ceramic dies, achieves up to 70% faster production speeds compared to conventional non-ultrasonic methods while delivering superior surface finish, reduced tool wear, and extended die life. Thanks to the unique Sialon composition (Si₃Al₃O₃N₅) – where silicon is partially substituted by aluminum and nitrogen by oxygen – these dies offer exceptional hardness, fracture toughness, thermal shock resistance, and wear resistance far beyond pure silicon nitride.
Key advantages include the best price/performance ratio on the market, extremely low maintenance and cleaning costs, virtually maintenance-free operation, and optimized performance for non-ferrous extrusion processes. Fully custom-made to your drawings with fast quotation turnaround (typically 4 weeks) and competitive pricing.
All Sialon ULTRA™ grades (ULTRA-001 to ULTRA-004) share these properties:
Part of our technical ceramics range since 1986, these dies complement our full portfolio for molten non-ferrous metal handling. View Sialon Extrusion Dies – upload your drawing today for a custom quote. Quality warranty included (12-month coverage against defects).
