professional pure W1 plate tungsten sheets surface polished  manufacturer

The production method of pure tungsten flakes with polished surfaces usually involves several steps. Here’s a general overview of the process:

Raw material selection: High-purity tungsten ingots are selected as raw materials for the production of tungsten flakes. Melting and Casting: Tungsten ingots are melted and cast into the desired shape, such as a slab or billet. Hot Rolling: Cast tungsten material undergoes a series of hot rolling processes to obtain the required sheet thickness and size. Annealing: Annealing is usually done to eliminate internal stress and improve the ductility of the tungsten sheet. Surface Grinding and Polishing: Tungsten discs are surface ground to remove any imperfections and achieve a smooth surface finish. Polishing techniques such as mechanical or chemical polishing are then used to further refine the surface to the desired level of smoothness and reflectivity. Quality Control: Finished tungsten sheets undergo quality control inspections to ensure they meet specified surface finish requirements and dimensional tolerances. 

Pure tungsten sheets with polished surfaces have numerous applications in different industries. The polished surface of tungsten wafers enhances their appearance, improves their corrosion resistance, and allows for better performance in certain applications. Here are some common uses for polished surface pure tungsten sheets: Industrial furnaces: Surface-polished tungsten sheets are often used as heating elements in industrial furnaces due to their high melting point and excellent thermal conductivity. The polished surface helps reflect heat efficiently and extends the life of the heating element. Aerospace and Defense: In aerospace and defense applications, pure tungsten sheets with polished surfaces are used in components such as heat shields, structural supports and radiation shielding due to their high density, strength and ability to withstand high temperatures. Electronics and Semiconductor Industry: Polished tungsten sheets are used in the production of sputtering targets, X-ray tubes and other electronic components due to their high density, stability and good electrical conductivity. Medical devices: Polished tungsten sheets can be used in medical devices such as radiation shields, collimators and counterweights due to their radiation resistance and biocompatibility. Lighting Industry: Surface-polished tungsten sheets are used to make light bulb filaments due to their ability to withstand high temperatures and provide reliable performance. Vacuum Furnace Industry: Polished tungsten flakes are used as heating elements, heat shields and supports in vacuum furnace applications due to their high purity, low vapor pressure and excellent thermal stability at high temperatures.

The polished surface of tungsten discs plays a key role in improving performance and durability in these applications. The smooth and reflective properties of the polished surface help mitigate oxidation, improve thermal efficiency and ensure consistent performance in demanding environments.
