❓ Frequently Asked Questions
💬
What is the tungsten purity of Yunjie Pure Tungsten Plates?
Yunjie Pure Tungsten Plates (Model W1) are manufactured with a tungsten content of ≥ 99.95%, ensuring ultra-high purity with virtually no impurities. This level of purity is critical for applications that demand consistent material performance and reliable electrical or thermal conductivity.
💬
What manufacturing process is used to produce these tungsten plates?
The plates are produced through a three-stage process: Powder Metallurgy (sintering tungsten powder into billets), followed by Pressure Processing (forging or rolling to achieve the desired thickness and density), and finally Vacuum Annealing to relieve internal stress and improve ductility. This combination ensures high density (19.3 g/cm³) and excellent mechanical properties.
💬
What surface treatment options are available for the tungsten plates?
Three surface treatment options are available: Polished Surface (smooth, mirror-like finish for precision applications), Pickled Surface (chemically cleaned to remove oxides and scale), and Rolled Surface (as-rolled finish suitable for general industrial use). Custom surface requirements can be discussed upon inquiry.
💬
Can Yunjie provide custom-shaped or precision-machined tungsten parts?
Yes. In addition to standard flat plates, Yunjie offers comprehensive processing services including Precision Cutting, Drilling, Bending, Welding, Machining, and Surface Polishing. Special-shaped parts can be manufactured on demand based on customer drawings or specifications, making it suitable for highly customized industrial and scientific applications.
💬
What is the minimum order quantity (MOQ) for Pure Tungsten Plates?
The minimum order quantity is 1 piece or 3 kg, whichever applies based on your actual order. This flexible MOQ policy makes it accessible for both prototype development and large-scale industrial procurement. Please contact us with your specific dimensions and quantity requirements for an accurate quotation.
💬
In which industries are Pure Tungsten Plates commonly used?
Pure Tungsten Plates are widely used in industries that require extreme heat resistance and structural stability, including aerospace (heat shields and rocket nozzle components), semiconductor manufacturing (sputtering targets and diffusion barriers), medical radiation shielding, high-temperature furnace components, electrical discharge machining (EDM) electrodes, and military and defense applications. The combination of high density, high melting point, and excellent conductivity makes tungsten an irreplaceable material in these fields.
