Sintered Tungsten Crucible

 

Types of Tungsten Machined Parts

The tungsten machined parts produced by our company mainly include the following types:

 

Sintered Tungsten Crucible
Rare earth tungsten crucible is mainly formed by sintering tungsten powder and then processed on a lathe.
Due to the high melting point and boiling point of tungsten, good high temperature strength, wear resistance and corrosion resistance, high thermal conductivity, small thermal expansion coefficient, and good hardenability, tungsten sintered crucibles are widely used in rare earth smelting, quartz glass, electronic spraying, crystal growth and other industries.

 

Tungsten Crucible For Evaporation Coating
Tungsten crucible is a crucible made of metal tungsten, which has the characteristics of high melting point, high strength and hardness, good high temperature performance, low resistivity, small expansion coefficient, and small electronic work function. Crucible is one of the important containers of evaporation coating equipment and optical coating equipment, mainly used for gold plating materials.

 

Benefits of Tungsten Machined Parts
 

Resistance to high temperatures
Of all metals in their purest form, tungsten has the highest melting point (3422°C). This can be hugely beneficial in certain situations (particularly when compared to other more common metals). For example, it makes tungsten an excellent material for high-temperature environments – and this is why it is so widely used in the aerospace, automatic and construction industries.

 

High-density
Tungsten benefits from a very high density. In fact, at 19.3 g/cm3, it is amongst the highest of all metals, with tungsten’s density measuring approximately 19.3 times higher than that of water and 1.7 times higher than that of lead.

 

Low thermal expansion
Tungsten machined parts has the lowest coefficient of thermal expansion of all pure metals. Compared to common manufacturing materials (e.g. steel), this gives it the benefit of added stability under extreme heat.

 

Corrosion-resistance
Tungsten machined parts is highly resistant to corrosion and can be used in a range of corrosive environments and outdoor applications. For example, it is particularly useful when prolonged exposure to corrosive substances – such as water, acid, or solvents – is likely.

 

Strength in fabrication
Tungsten is an extremely robust metal, with the highest tensile strength of all pure metals. While this can make it brittle under certain circumstances, when it comes to the process of metal fabrication, tungsten’s rigidity means that it can be drawn into very thin wires without fracturing.

 

Process Flow for the Machining of Tungsten Machined Parts
 

Smelting Process (if applicable)

Batching and Mixing: Tungsten powders are carefully selected and mixed to specified ratios.
Crushing and Drying: The mixture is then crushed and dried to achieve uniformity and optimal flowability.
Binder Addition and Granulation: Binders are added, followed by additional drying and sieving. This granulated mixture is then ready for pressing.

 

Sintering and Inspection

Sintering: The pressed tungsten is sintered in a vacuum low-pressure sintering furnace to form solid blanks.
Quality Inspection: These blanks undergo rigorous inspections, including ultrasonic testing and dimensional checks, to ensure they meet quality standards.

 

Molding and Machining

Molding: The sintered blanks are molded into the desired shapes and sizes.
Machining: This includes various high-precision mechanical operations such as:
Wire EDM (Electrical Discharge Machining)
CNC lathe machining
Turning, milling, and drilling
Grinding (surface, contour, internal, and external)
EDM machining

 

Heat Treatment

Though not always necessary, heat treatment is sometimes applied to:
Eliminate internal stresses
Achieve specific hardness tolerances

 

Surface Treatment

To enhance wear resistance and achieve fine surface finishes, surface treatments are applied:
Mirror Polishing: To attain extremely fine surface roughness.
PVD Coating: Commonly used to further enhance wear resistance and hardness.

 

Quality Testing

After each processing step, stringent quality testing ensures that the product adheres to all specifications. Tests measure:
Dimensional accuracy
Surface quality
Hardness
Mechanical properties

FAQ

 

Q: What Are the Applications of Tungsten Crucible?

A: Thanks to tungsten’s high melting point, high-temperature strength, great pyro conductivity, and good hardenability, tungsten crucible can be used under vacuum and inert gases below 2600℃. Tungsten crucible is widely used in industries including rare earth metallurgy, quartz glass, MOCVD equipment, and electronic spraying. In addition, tungsten crucibles can be used for sapphire crystal growth furnaces due to their high-temperature resistance, low pollution, and other excellent characteristics.

Q: Are tungsten crucibles good?

A: Tungsten crucibles offer unmatched advantages in high-temperature and corrosive environments, making them indispensable in both scientific and industrial applications. Their exceptional durability, resistance to extreme temperatures, and corrosion-resistant properties ensure consistent performance and reliability.

Q: Is tungsten scratch proof?

A: Tungsten is highly scratch-resistant but not entirely scratch-proof. It is one of the hardest metals, making it very durable and resistant to everyday scratches.
