Chapter 1 Basic Concepts and Development History of Tungsten Alloy Plates
1.1 Definition and basic characteristics of tungsten alloy plate
Tungsten alloy plate is a sheet-like alloy material made primarily of tungsten (W) with appropriate amounts of nickel (Ni), iron (Fe), copper (Cu), cobalt (Co), or other elements added through powder metallurgy, hot rolling, cold rolling , or additive manufacturing . Due to tungsten’s inherently high melting point (3422°C), excellent density (19.25 g/cm³), good thermal conductivity, and radiation resistance, tungsten alloy plate is widely used in a variety of key applications, including aerospace, nuclear power, protective armor, medical equipment, high-temperature structures, and electronic thermal management .
- Definition of Tungsten Alloy Plate
From the perspective of materials science, tungsten alloy plates are mainly composed of a high proportion of tungsten powder, supplemented by a small amount of bonding phase metal (usually Ni-Fe, Ni-Cu or Ni-Co system) to form a dense multiphase alloy system. Its form is usually a rectangular or special-shaped flat metal plate with a thickness of 0.1 mm to 50 mm and customizable length and width. Compared with traditional tungsten rods or tungsten wires, tungsten alloy plates have a larger surface area, are easier to cut, and can be used for multifunctional purposes such as covering, shielding, and structural parts manufacturing.
- Main Composition and Classification of Tungsten Alloy Plates
According to different alloy composition, forming method and application, tungsten alloy plates can be divided into the following categories:
- Classification by alloy system :
- W-Ni-Fe alloy plate (common type, high strength, high density, good mechanical properties)
- W-Ni-Cu alloy plate (non-magnetic type, used in electronics and medical fields)
- W-Cu alloy plate (high thermal conductivity, suitable for electronic heat dissipation and electrode applications)
- W-Co alloy plate (enhanced wear and corrosion resistance)
- Nano tungsten alloy plate (using nanoparticle strengthening technology to improve toughness and micro stability)
- Classification by production process :
- Powder metallurgy sheet (molding/isostatic pressing + sintering + hot processing)
- Rolled tungsten alloy plate (hot rolled/cold rolled and then processed)
- Additive manufacturing of tungsten alloy sheets (new technologies such as laser melting and 3D printing)
- Composite tungsten alloy plates (such as W-Cu sandwich structures, tungsten-titanium composite plates, etc.)
- Classification by function :
- Structural tungsten alloy plate : structural components that bear static loads and impact loads
- Functional tungsten alloy plate : has specific physical functions such as thermal conductivity, anti-magnetic, and anti-radiation
- Shielding tungsten alloy plate : used for radiation protection, medical radiotherapy equipment, etc.
- Key Performance Characteristics of Tungsten Alloy Plate
- High density : The density of a typical tungsten alloy plate is between 17.0 and 18.5 g/cm³, which is 2.2 times that of steel of the same volume. It is effectively used for inertial loads, dynamic balance and radiation shielding.
- Excellent mechanical properties : It has high tensile strength (usually up to 700-1000 MPa), good impact toughness and processability, and is suitable for manufacturing parts with complex shapes.
- High temperature stability : Tungsten-based alloys can maintain stable structure and performance above 1000°C, and are suitable for vacuum high-temperature furnaces and thermal field systems.
- Good thermal and electrical conductivity : Especially in the W-Cu alloy system, the thermal conductivity can reach 170-220 W/ m·K , and is widely used in heat dissipation structures and electronic substrates.
- Excellent radiation resistance : Tungsten’s high atomic number and high density give it excellent X-ray and gamma-ray shielding effects, far superior to traditional lead plates.
- Good chemical stability and corrosion resistance : Stable in neutral and weakly acidic environments, and outperforms other heavy metals in high temperature or strong oxidizing environments.
- Overview of the shape and specifications of tungsten alloy plates
Tungsten alloy plates are usually customized in size according to user requirements. Typical specifications are as follows:
- Thickness range: 0.1 mm ~ 50 mm
- Width range: 10 mm to 600 mm
- Length range: 10 mm to 2000 mm
- Surface condition: lathing, grinding, polishing, chemical plating, PVD coating, etc.
Some high-precision applications (such as particle accelerators and nuclear magnetic equipment) also require a surface roughness Ra < 0.2 μm and a thickness tolerance within ± 0.01 mm.
- Comparative advantages of tungsten alloy plates and traditional metal plates
| Performance parameters | Tungsten Alloy Plate | stereotype | Steel Plate | Copper Plate |
| Density (g/cm³) | 17.0～18.5 | 11.3 | 7.8 | 8.9 |
| Melting point (°C) | 2700+ | 327 | 1500 | 1083 |
| Shielding capability | Very strong (gamma/neutron) | General (X/γ) | weak | generally |
| Thermal conductivity | good | Difference | generally | Excellent |
| High temperature stability | Excellent | Difference | generally | Difference |
| Environmental protection | High (non-toxic) | Low (toxic) | high | high |
Tungsten alloy plates are gradually becoming an alternative material to lead and steel in special functional fields due to their strength, density, thermal properties and environmental protection attributes.
In summary, tungsten alloy plate, as an advanced material with high density, high strength, high temperature stability and excellent shielding ability, shows important value in modern high-end manufacturing and precision applications. With the continuous advancement of preparation technology and the reduction of process costs, its application scope is gradually expanding from the military and nuclear energy fields to a wider industrial system such as electronics, medical, aerospace, etc.
1.2 Brief History of the Formation and Development of Tungsten Alloy Plates
an important high-performance metal material, the development of tungsten alloy plate is closely accompanied by the progress of powder metallurgy technology, the strategic development of tungsten resources and the continuous pursuit of material performance in extreme environments in high-end industrial fields. From early experimental applications to today’s widespread deployment in key fields such as nuclear industry, aerospace, and medical protection, the development history of tungsten alloy plate is not only a microcosm of the evolution of metal material technology, but also reflects the global manufacturing industry’s leap from conventional metals to ultra-high performance functional materials.
- Discovery and early research of tungsten materials
Tungsten (W) was first known to humans in the mid-18th century. In 1781, Swedish chemist Carl Wilhelm Scheele first extracted tungsten oxide from sodium tungstate, and a few years later, the Spanish Elhuyar brothers (Juan José and Fausto Elhuyar ) successfully separated metallic tungsten. Tungsten is known for its extremely high melting point (3422°C) and density (19.25 g/cm³), and it was quickly used in incandescent filaments, electrical contacts and high-temperature alloys.
However, due to the inherent brittleness and difficulty in processing tungsten , traditional metallurgical methods have made it difficult to form it into thin sheets or plates. Therefore, early attempts at “tungsten alloy plates” remained largely at the laboratory research stage, and its actual engineering application did not gradually emerge until the mid-20th century.
- The rise of powder metallurgy technology and the realization of sheet metal forming
In the early 20th century, with the rapid development of **powder metallurgy** technology, scientists began to try to process high-melting-point refractory metals (such as tungsten and molybdenum ) into structural parts through pressing and sintering. This technology was studied intensively before and after World War II, especially in the military industrial systems of the United States, Germany, the Soviet Union and other countries, and eventually promoted the actual production of products such as tungsten alloy plates.
1950s to the 1970s , with the development of atomic energy and aerospace technology, the demand for high-density, high-strength, and radiation-proof materials increased sharply, and high-density tungsten alloy systems such as W-Ni-Fe and W-Ni-Cu were systematically established. During this period, tungsten alloy plates were mainly prepared by pressing sintering + hot rolling process, and the industrial production of thin plate parts was initially realized, mainly used for:
- Shielding plates and neutron absorbers for atomic reactors;
- Aircraft and missile counterweight systems;
- X-ray/gamma ray shielding components in the medical field.
- Technology maturity driven by applications (1980s-2000s)
In the 1980s , with the popularization of medical radiotherapy equipment, the rapid development of the electronics industry, and the urgent requirements of environmental regulations for “lead substitutes”, the demand for tungsten alloy plates increased sharply. During this period, the development of tungsten alloy plate technology showed the following important trends:
- Precision rolling and cold processing technology significantly improves the thickness control accuracy and surface quality of the plate;
- Developed non-magnetic W-Ni-Cu alloys to solve the magnetic interference problem in medical magnetic resonance imaging and some aerospace equipment;
- Composite structural plates (such as W-Cu sandwich structures) have emerged to achieve multi-performance integration;
- The quality management system is becoming increasingly standardized, and many national and industry standards have been introduced, such as ASTM B777, GB/T 3879, etc.
At this time, tungsten alloy plates have gradually evolved from early structural materials to integrated materials with both structure and function. They are widely used in many high-end fields such as precision instruments, thermal management systems, radiation protection shielding, and high-temperature furnace wall panels.
