Molybdenum and Tungsten Crucibles
Elmet produces molybdenum and tungsten material and components for leading sapphire growth furnace OEMs and crystal growers around the world. Elmet provides a variety of crucibles for sapphire growth furnaces, as well as many other components for these furnaces. Corrosion resistance, creep resistance, and high-temperature performance make molybdenum and tungsten crucibles ideal for use in high-temperature crystal growth processes. Crystal growth is at the foundation for many cutting edge technologies such as Sapphire touch screens, LED lighting parts, solar cells, and high power lasers. Elmet is continually improving manufacturing and materials processes to meet the evolving requirements of this industry. From raw material to finished product, Elmet’s integrated manufacturing process, quality systems, and metallurgical expertise ensure we deliver quality components for the crystal growth industry.
Pressed and Sintered Crucibles
- Powder is pressed and sintered to final shape geometries to meet the requirements of each furnace design
- Large molybdenum plate blanks are hot spun formed to the specified product geometry
- Elmet has experience in a wide variety of molybdenum crucible sizes up to 20″ diameter
- Material blanks are machined to the final product geometries
Elmet works closely with leading furnace OEMs and crystal growers across the globe to continually improve the yield and throughput of their growth process through improved crucible design. As a result, Elmet is on the leading edge of crucible manufacture and fabrication. Contact us to help address the challenges in improving your current and next-generation growth processes.
Given our position as a well-established manufacturer of Mo and W products for over 80 years, Elmet offers a stable partner and supply of products to our customers that enable them to achieve their aggressive growth targets and capture market share as competitors struggle to deliver.
About our process
Since 1929, Elmet Technologies has provided our customers with innovative, high-quality molybdenum and tungsten products. We have been a long-time supplier to the high-temperature furnace industry and we are ramping up production at our new location in Covington, GA to better serve the sapphire growth industry. Our Covington facility operates large capacity pressing, sintering, rolling, and spinning equipment for efficient volume production of both spun, pressed and sintered crucibles. The equipment at this location comprises the largest fully integrated crucible manufacturing plant in North America. In addition to crucibles, Elmet produces hot zone components and mill products, and also offers assembly and machining services. As a fully integrated manufacturer of molybdenum and tungsten — from the metal powder to the final product — we maintain full control throughout the manufacturing process to ensure consistent, reliable product quality.
