Our production begins with premium-grade niobium feedstock sourced from certified suppliers. We use electron beam melting technology in ultra-high vacuum conditions to achieve exceptional purity levels.
The melting process occurs at temperatures exceeding 2400°C. This removes volatile impurities and creates a homogeneous microstructure. After solidification, we perform hot working operations to achieve your desired dimensions.
Cold drawing and precision machining ensure tight dimensional tolerances. Each high purity niobium bar undergoes stress relief annealing to optimize mechanical properties and remove residual stresses.
Our controlled atmosphere throughout production prevents contamination and maintains the ultra-clean composition you need.
Every batch receives comprehensive testing to verify composition and properties. We use inductively coupled plasma mass spectrometry for trace element analysis. Oxygen, nitrogen, and carbon levels are measured using dedicated gas analyzers.
Mechanical testing includes tensile strength, yield strength, and elongation measurements. Ultrasonic inspection detects internal defects. Surface quality inspection ensures smooth, defect-free finishes.
Dimensional verification confirms all bars meet your specified tolerances. We provide complete test certificates with every shipment documenting all measured properties.
We protect your bars during transport using specialized packaging designed for reactive metals. Each high purity niobium bar is individually wrapped in protective film and placed in custom foam inserts.
Moisture-resistant containers prevent oxidation during shipping. Proper labeling ensures safe handling and customs clearance. We work with trusted logistics partners to ensure timely, damage-free delivery worldwide.
For air-sensitive applications, we offer vacuum-sealed packaging options. Rush orders receive priority processing and expedited shipping when needed.
