Pure Tungsten Plate - Kingdon manufactures 99.95% pure tungsten plates in thicknesses from 0.05 mm to 50 mm, conforming to ASTM B760 and GB/T 3875. Every plate is lot-controlled and ships with a material certificate (MTC).
Of all metals in pure form, tungsten has the highest melting point (3410 °C / 6192 °F), the lowest vapor pressure (below detectable limits above 1650 °C), and the highest tensile strength at elevated temperatures. This makes pure tungsten plate the material of choice for ultra-high-temperature furnaces, high-vacuum applications, semiconductor base plates, and X-ray shielding.
Purity ≥ 99.95% ｜ Density 19.3 g/cm³ ｜ Melting point 3410 °C ｜ Standards ASTM B760 / GB/T 3875 ｜ MOQ: 1KGS ｜ Custom cut-to-size available.
Why Pure Tungsten?
Lowest thermal expansion of any pure metalTungsten's coefficient of thermal expansion (CTE, 4.5 × 10⁻⁶/K) closely matches semiconductor materials such as Si, GaN, and GaAs, and it remains dimensionally stable at high temperature - ideal for electronic packaging, heat sinks, and hermetic seals. |
Low electrical resistivity among refractory metals5.65 × 10⁻⁸ Ω·m at 20 °C, critical for high-temperature furnace electrodes and heating elements. |
Exceptional density of 19.3 g/cm³With high X-ray and gamma-ray absorption, making tungsten plate an effective radiation shielding material where lead is not acceptable. |
Superior high-temperature strengthTungsten retains its tensile strength at temperatures where most metals have already lost theirs, and its low vapor pressure ensures a clean vacuum environment. |

FAQ - Pure Tungsten Plate
|
Q1: What is a pure tungsten plate? A pure tungsten plate is a flat-rolled product made from tungsten with a purity of 99.95% or higher, manufactured by pressing and sintering tungsten powder and then rolling. It offers a melting point of 3410 °C and a density of 19.3 g/cm³, and is used in high-temperature furnaces, semiconductor equipment, and radiation shielding. |
Q2: What standards does your tungsten plate comply with? Our pure tungsten plate conforms to ASTM B760 (international) and GB/T 3875 (Chinese national standard). A material test certificate is provided with every lot. |
|
Q3: What thickness and size range do you offer? Thickness 0.05–50 mm, width 50–600 mm, length 100–2000 mm. Custom cut-to-size plates are available from your drawing. |
Q4: What is the difference between tungsten plate and tungsten sheet? In common industry usage, tungsten sheet refers to thinner gauge material (typically below 0.5 mm), while tungsten plate refers to thicker flat products. We manufacture both. |
|
Q5: Can you supply custom tungsten plates with special dimensions or tolerances? Yes. We cut tungsten plate to size from 1 pc and can machine to your drawing, including drilled, ground, and polished finishes. MOQ is 1KGS. |
Q6: What is the lead time for a tungsten plate order? Normally 10–20 working days depending on size and quantity. In-stock sizes can ship sooner - contact us for current availability. |
|
Q7: How do you pack and ship tungsten plates? Standard export packing in plywood cases with cushioning to protect edges and surfaces. We ship worldwide by air or sea freight, DHL/FedEx/UPS for samples. |
Q8: Can I get a sample of your pure tungsten plate? Yes, samples are available. Contact us with your required size and we will respond within 24 hours. |
