A Comprehensive Guide to Tungsten Sheet in China
China is a global leader in tungsten production, boasting approximately 60% of the world’s tungsten ore reserves. This abundance, coupled with advanced manufacturing capabilities, makes China a primary source for tungsten sheet globally. This guide delves into the intricacies of tungsten sheet, exploring its properties, applications, and the diverse types available from Chinese suppliers.
Understanding Tungsten Sheet
Tungsten sheet, also known as tungsten plate or foil, is a versatile material prized for its exceptional properties. Its high melting point (over 3400°C), high density, and excellent corrosion resistance make it ideal for demanding applications. Companies like iTop Metal (www.itopmetal.com) highlight its use in high-temperature furnace components, radiation shielding, and heat dissipation in electronics. The material’s high tensile strength and low coefficient of thermal expansion further enhance its value. These characteristics are crucial in aerospace, military, and medical industries.
Technical Features of Tungsten Sheet
The specific properties of tungsten sheet vary depending on the manufacturing process and alloying elements. Purity levels greatly influence performance characteristics. Advanced techniques such as vacuum melting and precision rolling, as employed by iTop Metal, ensure uniformity and high purity. BJHS Metal (www.bjhsmetal.com) and other manufacturers offer various grades catering to specific needs. The following table compares key features:
| Feature | Pure Tungsten Sheet | Tungsten-Copper Alloy Sheet | Tungsten-Molybdenum Alloy Sheet | Tungsten Heavy Alloy Sheet |
|---|---|---|---|---|
| Density (g/cm³) | ~19.3 | Varies (depending on composition) | Varies (depending on composition) | 17-19 (depending on composition) |
| Melting Point (°C) | ~3422 | Lower than pure tungsten | Lower than pure tungsten | Lower than pure tungsten |
| Tensile Strength (MPa) | High | High | High | Very High |
| Ductility | Low | Improved | Improved | Moderate |
| Corrosion Resistance | Excellent | Excellent | Excellent | Excellent |
| Electrical Conductivity | High | High (due to copper content) | High | Lower than pure tungsten |
| Thermal Conductivity | High | High (due to copper content) | High | Lower than pure tungsten |
| MaChinability | Difficult | Easier than pure tungsten | Easier than pure tungsten | Easier than pure tungsten |
Types of Tungsten Sheet
Several types of tungsten sheet are available, each tailored to specific application requirements. The choice depends on factors like desired density, strength, ductility, and cost. Kedipu (www.kdpmetal.com) and other suppliers offer a range of options. The following table outlines the differences:
| Type of Tungsten Sheet | Composition | Key Properties | Typical Applications |
|---|---|---|---|
| Pure Tungsten Sheet | >99.95% Tungsten | High melting point, high strength, excellent corrosion resistance | Electronics, aerospace components, high-temperature furnaces |
| Tungsten-Copper Alloy | Tungsten + Copper | High thermal conductivity, good electrical conductivity, improved maChinability | Heat sinks, electrical contacts, high-temperature applications |
| Tungsten-Molybdenum Alloy | Tungsten + Molybdenum | Improved toughness, high-temperature resistance | High-temperature furnace components, thermocouple protection tubes |
| Tungsten Heavy Alloy | Tungsten + Nickel + Iron/Copper | Very high density, high strength, radiation shielding | Radiation shielding, counterweights, armor-piercing cores |

FAQs
1. What are the main applications of tungsten sheet?
Tungsten sheet finds applications in diverse sectors, including electronics (heat sinks, semiconductor components), aerospace (radiation shielding, counterweights), and medical (X-ray shielding). Its high melting point and corrosion resistance make it vital for high-temperature furnace parts.
2. What are the differences between pure tungsten sheet and tungsten alloy sheets?
Pure tungsten sheet boasts superior high-temperature properties, but is less ductile and harder to machine. Tungsten alloys, like tungsten-copper or tungsten-molybdenum, offer improved maChinability and other properties tailored to specific needs.
3. How can I find a reliable tungsten sheet supplier in China?
Online B2B platforms like TradeWheel are helpful. Directly contacting manufacturers’ websites is another option. Thorough due diligence, including checking certifications and customer reviews, is crucial for selecting a trustworthy supplier.
4. What are the typical thicknesses and sizes available for tungsten sheet?
Thicknesses range from fractions of a millimeter to tens of millimeters, while width and length can vary greatly depending on the manufacturer and specific order. Customized sizes are often available.
5. What are the common payment methods for purchasing tungsten sheet from China?
Telegraphic Transfer (TT) is a prevalent method, often requiring an advance payment. Letters of Credit (L/C) and other methods might also be accepted depending on the supplier and buyer agreement.
