Tungsten Foil

Description and Specification of Tungsten Foil

A tungsten sheet is a super-thin slice of rigid Tungsten metal. It is strong, hard to break, and can handle high heat and rust. The tungsten dust is shaped into a bar and flattened to make these sheets. Afterward, methods like squeezing it in a vacuum, rolling it hot or cold, and baking it to get it super-thin are used. Making tungsten sheets is complex but worthwhile. It requires advanced equipment like specialized mills and presses to produce a sleek, dark, and delicate metal surface, sometimes just a fraction of a millimeter thick. Tungsten sheets come in various dimensions and shapes. The foil often looks like steel but can be finished to meet specific needs. Companies that produce tungsten foil serve many industries. It is perfect for hot furnaces, coating methods, and electronic parts. The extreme thinness of tungsten sheets allows to combine with other materials such as metal or glass. This universal product is vital in many manufacturing processes, from high-tech electronics to industrial machinery.

Features of Tungsten Foil

Silver Surface

Tungsten foil has a distinctive, lustrous silver shine on its surface. This aesthetic quality makes it visually appealing for various applications, especially in decorative or visible components.

Radiation Shielding

The foil provides radiation shielding properties comparable to lead plates. This feature makes the foil an excellent choice for medical and industrial applications where radiation protection is crucial.

Easy to customize

It is thin enough to cut with regular scissors. Therefore, it can be easily customized and integrated into various products and systems.

Highly Durable

It demonstrates excellent strength. It can withhold repeated bending, folding, and retraction without losing its integrity. This durability ensures long-lasting performance in demanding applications.

Environmentally Friendly

Tungsten is simple and does not pose considerable environmental hazards compared to other metals in similar applications, making it a preferable choice for industries.

High Thermal Plasticity

It can be easily molded into objects with cylindrical or intricately curved surfaces, which improves its application in manufacturing processes.

High Melting Point

Tungsten sheets stay strong even in extremely high temperatures without falling apart. This makes the sheets perfect for super-hot ovens and other places where regular metals would melt or weaken.

Low Vapor Pressure

The low vapor pressure of it makes it suitable for use in vacuum environments. This property is precious in applications such as vacuum furnaces and specific electronic components.

Applications

Tungsten foil is used in industrial furnaces because it can withstand high temperatures. Due to its high melting point and low vapor pressure, tungsten foil is also used in evaporation boats and semiconductor components. It is used as a base material for capacitors, vacuum tubes, and thin-film circuits in the electrical and electronics industries.

Tungsten foil is used to manufacture rocket nozzles, heat shields, and radiation protection for spacecraft in the aerospace and defense sectors. It is also used for X-ray targets, radiation shields, and surgical instruments. The energy sector, the automotive industry, jewelry making, and luxury goods production also use tungsten foil.

How to Use?

• Store the product in airtight containers at room temperature.
• Avoid exposure to light and moisture.
• Make sure there is enough ventilation.
• Use local exhaust ventilation or engineering controls to maintain exposure below occupational limits.
• Good housekeeping and sanitation must be followed.
• To prevent fire hazards, avoid dust collection.

Safety Guidelines

• Use NIOSH-approved dust respirator if permissible levels are exceeded
• Avoid creating and breathing dust or fumes
• To protect eyes, use safety glasses.
• Use impervious gloves and protective work clothing
• Wash hands thoroughly after every use and before using hands for eating.
• Provide ventilation and vacate the area if there is any leakage or spill.
• If there is leakage, immediately clean it to avoid dust formation.
