Uses of tungsten rhenium wire

Tungsten-rhenium filament is a high-performance alloy wire made by adding a small amount of rhenium to tungsten. It perfectly inherits the high melting point and high strength of tungsten, and achieves revolutionary improvements due to the “rhenium effect”: it does not become brittle after recrystallization, has higher high-temperature strength, and a longer lifespan. This makes it a key material for extreme environments, primarily used in the following high-end fields: 1. The “Heart” of Electrovacuum and Electric Light Source Devices This is the most classic application area for tungsten-rhenium filament. In high-temperature vacuum environments, pure tungsten filament is prone to brittleness and has a short lifespan, while tungsten-rhenium filament exhibits irreplaceable advantages: Filaments and Cathodes: Widely used in high-reliability electron tubes, high-power magnetrons (such as microwave oven cores), X-ray tubes, etc. Its anti-sagging and shock-resistant properties can withstand the thermal shock of repeated power-on and power-off cycles, greatly extending the lifespan of the device. Special Light Sources: Used in cinema projection lamps, searchlights, etc., it can operate stably at higher temperatures, providing brighter and whiter light. 2. A “Scale” and “Heat Source” in Ultra-High Temperature Environments Thermocouples (Temperature Measurement): Tungsten-rhenium thermocouples are the preferred tool for measuring ultra-high temperatures of 1600℃...

The Silent Foundation of Diamond Growth: Exploring Molybdenum Circular Diamonds in CVD Technology

A molybdenum wafer is a disc-shaped base made of high-purity metallic molybdenum, typically with a mirror-like surface. In CVD diamond growth equipment, it sits quietly within the vacuum reaction chamber, enduring temperatures approaching 1000 degrees Celsius. This unassuming component provides the initial support for diamond growth. The diamond growth environment is extremely harsh, and the material properties of the molybdenum wafer perfectly meet this requirement. Its most prominent advantage lies in its extremely high melting point of 2620°C, which allows it to maintain structural stability even at the high temperatures of 800-1200°C required for diamond growth. More importantly, molybdenum and carbon atoms can form a stable molybdenum carbide thin layer on the surface. This property prevents carbon atoms from diffusing further inward and provides an ideal adhesion interface for the diamond nucleus. In actual production, the molybdenum wafer plays multiple crucial roles. It is the carrier of the diamond seed crystal—fixing carefully selected diamond flakes onto the surface of the molybdenum wafer as a template for crystal growth. Under the influence of microwave plasma, carbon-rich gas decomposes above the molybdenum wafer, and carbon atoms are deposited in an orderly fashion according to the crystal structure of the seed crystal, like...

Uses of tungsten plates

Tungsten steel plates, with their high density, high melting point, and excellent radiation shielding capabilities, have become key materials in the nuclear energy and medical fields. They are widely used in the manufacture of shielding components for nuclear reactors, linings for nuclear fuel storage containers, and collimators and protective components in CT scanners and radiotherapy equipment, achieving superior protection compared to lead with thinner thicknesses. In high-temperature industries and electronics, the high-temperature resistance of tungsten steel plates is irreplaceable. They are commonly used in heating plates in semiconductor manufacturing, gates and supports for vacuum electronic devices, and heating elements and heat shields in vacuum sintering furnaces and sapphire crystal growth furnaces, maintaining structural stability and performance in extreme environments exceeding 2000°C. Furthermore, the high density and strength of tungsten steel plates make them a core material for manufacturing armor-piercing projectile cores in the military. Their excellent corrosion resistance also makes them crucial components in plasma welding, special smelting, and chemical equipment, serving as resistant to molten metal and highly corrosive media.

Is tungsten-nickel-iron alloy magnetic?

In summary: Yes, WNiFe alloy is magnetic. The magnetic properties of tungsten-nickel-iron alloy primarily come from its two key components: nickel and iron. Nickel and iron are both typical ferromagnetic elements. This means they can be strongly magnetized at room temperature, making them important raw materials for manufacturing magnets and magnetic materials. Tungsten itself is paramagnetic. Paramagnetic materials exhibit only a weak degree of magnetism in the presence of a strong external magnetic field; when the field is removed, the magnetism disappears. It does not possess the strong magnetic properties of iron. When tungsten is sintered with nickel and iron through powder metallurgy to form a dense alloy, the alloy’s microstructure no longer consists of its individual elements, but rather forms a new phase. In this alloy, iron and nickel provide the foundation for ferromagnetism, giving the entire alloy a macroscopically magnetic appearance.
