Product Details

Tungsten components for sapphire crystal growth furnaces feature an ultra-high melting point exceeding 3410°C. The maximum sustainable operating temperature stands at 2000°C for tungsten parts and 1700°C for molybdenum counterparts, respectively.

Our sapphire furnace tungsten and molybdenum components deliver outstanding advantages including high purity, full density, mirror-smooth surfaces and precise dimensional accuracy.

Manufactured with ultra-low carbon, oxygen and iron content, these tungsten & molybdenum furnace components effectively improve crystal yield, stabilize crystal quality and extend service lifespan throughout the sapphire growth cycle.

We apply precision integrated forming techniques across the entire production workflow, which guarantees minimal machining tolerances for all custom tungsten and molybdenum furnace parts.

Applications：

1. Crucibles and other parts for Sapphire crystal growth and rare-earth melting
2. Sputtering Target
3. Parts of industrial furnace
