Manufacturing Process

Precision Manufacturing Process of Niobium C103

Our Niobium C103 sheet and foil undergo carefully controlled manufacturing stages to meet specified material, dimensional and quality requirements.

01

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.

02

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.

03

Hot Rolling

The ingot is heated to precise temperatures and rolled to reduce thickness while enhancing mechanical properties through controlled deformation.

04

Cold Rolling & Annealing

Precision cold rolling achieves final thickness with tight tolerances, followed by vacuum annealing to optimize mechanical properties and remove residual stresses.

05

Quality Inspection & Testing

Each sheet undergoes rigorous testing including chemical analysis, mechanical property verification, ultrasonic inspection, and dimensional checks to ensure compliance.

C103 Sheet / Foil Processing & Technical Requirements

Explore the key processing requirements for C103 niobium alloy sheet and foil, including rolling, forging, surface cleaning, heat treatment, and the overall manufacturing sequence

ROLLING / 01

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 / 02

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 / 03

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, 90%-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 / 04

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.
