Product Overview

High Purity Tungsten Crucible for Extreme Temperature Applications

ZSWMO manufactures high purity tungsten crucibles for demanding high-temperature environments including sapphire crystal growth furnaces, vacuum furnaces and semiconductor processing equipment.

Tungsten is one of the most reliable refractory metals due to its extremely high melting point of 3422°C, excellent thermal stability and outstanding resistance to deformation under high temperatures.

Our tungsten crucibles are produced using high purity tungsten materials and precision manufacturing processes to ensure excellent dimensional accuracy, structural stability and long service life.

We provide standard and customized tungsten crucibles according to customer drawings, furnace models and application requirements.
