Precision Manufacturing Process of Niobium C103
Our Niobium C103 Sheet & Foil undergo a rigorous manufacturing process to ensure the highest quality and performance standards.
1. Alloy Preparation
High-purity niobium, hafnium, and titanium are precisely measured and blended according to the C103 specification (Nb-10Hf-1Ti) to ensure exact chemical composition.
2. Vacuum Arc Melting
The alloy is melted in a high-vacuum environment to eliminate gas impurities and ensure homogeneous composition, creating a uniform ingot structure.
3. Hot Rolling
The ingot is heated to precise temperatures and rolled to reduce thickness while enhancing mechanical properties through controlled deformation.
4. Cold Rolling & Annealing
Precision cold rolling achieves final thickness with tight tolerances, followed by vacuum annealing to optimize mechanical properties and remove residual stresses.
5. Quality Inspection & Testing
Each sheet undergoes rigorous testing including chemical analysis, mechanical property verification, ultrasonic inspection, and dimensional checks to ensure compliance.
Rolling requirements of C103 Sheet/Foil
Usually cold rolling is used, the total processing rate is controlled at 80%-90% of the slab thickness, and the pass processing rate is controlled at 6%-8% of the slab thickness. In order to ensure the surface quality of the plate, the forged slab blank is required to be free of defects, pollution, and the roller surface is smooth.
Forging requirements of C103 Sheet/Foil
Forging billeting is best to use press cold forging, the temperature rise of the forging should not exceed 400°C (the surface of the forging is blue at 400°C), and the uniformity of the material is good, which can reduce the pollution of gas impurities.
Cleaning requirements of C103 Sheet/Foil
Before annealing, the surface contamination layer must be removed by pickling. The pickling solution is configured with 65%-68% nitric acid, 9%-98% sulfuric acid and not less than 40% hydrofluoric acid in a volume ratio of 5:5:2, and rinse with water after pickling.
Heat treatment specification of C103 Sheet/Foil
In the vacuum state of 1×10^(-3)Pa, heat up to 800°C with the furnace, keep for 1 hour, C103 heat up to 1100-1600°C at no more than 20°C/min, keep the temperature for 2.5 hours, cut off and cool down It is baked at not more than 60°C.
