99.95% Niobium Nb Round Disc

Product Description

Niobium Disc is a disc-shaped material made from the metal element niobium (Nb). It has a high melting point (2468℃), good corrosion resistance, excellent superconductivity, and anti-magnetism. These characteristics make niobium discs irreplaceable in high-end industry, scientific research and special technology fields.

99.95% Niobium Nb Round Disc Features

• The density is between copper and iron, the tensile strength is close to stainless steel, and the elastic modulus is better than titanium alloy.
• Excellent superconducting properties, zero resistance and complete anti-magnetism in a liquid helium environment.
• Resistant to corrosion by acids, alkalis and molten salts, with a natural oxide film on the surface and strong self-repairing ability
• Easy to perform plastic processing and high-precision processing, which can meet the customized requirements of different customers.
• The melting point is higher than that of most metals, with high thermal conductivity and a low thermal expansion coefficient.

99.95% Niobium Nb Round Disc Application

• Aerospace: Replace nickel-based alloys in engine combustion chambers, rocket nozzles and other parts, reduce weight by 15%-20%, and withstand high temperatures above 1500℃
• Electronic communications: Used for heat dissipation substrates and radio frequency components. Use niobium's high thermal conductivity and low dielectric constant to improve signal transmission efficiency
• Optical instruments: Used as a target to sputter and deposit niobium films as an anti-reflection layer for infrared filters or laser lenses, which can improve clarity and transmittance.
• Medical industry: Used as structural support or superconducting coil frames for magnetic resonance imaging equipment, which is conducive to improving imaging speed and resolution.

99.95% Niobium Nb Round Disc Process

1. The purity of niobium is increased to above 99.95% by Electron beam melting or zone smelting technology
2. The as-cast structure defects were eliminated and the grains were refined by the processes of cogging, upsetting and drawing at the high temperature of 1200-1400 °C.
3. After hot rolling, the plate is thinned gradually to the required thickness of the disk by cold rolling (the precision can reach ± 0.005 mm) .
4. Vacuum annealing should be carried out after cold working to eliminate internal stress and prevent deformation in use.
5. EDM (Electrical discharge machining grinding) or ultra-precision grinding techniques are used to ensure that the finished product can meet the assembly requirements of optical-grade or superconducting devices.
6. After the completion of all processing will be a comprehensive quality inspection to ensure that products meet international standards.
