Sintered Tungsten Bar

Sintered tungsten rod features a uniform silver-gray metallic luster on its entire surface with smooth texture and no obvious defects such as cracks, pores or oxidation spots. Adopting medium-frequency sintering furnace as core production equipment, the product is manufactured via indirect heating sintering technology under a constant and uniform temperature field. This precise production process ensures consistent internal structure, stable density and excellent overall performance of the tungsten rod, effectively avoiding performance deviation caused by uneven heating.

Benefiting from the inherent physical and chemical properties of high-purity tungsten materials and standardized sintering process, the sintered tungsten rod boasts superior comprehensive properties: ultra-high melting point, extreme hardness, excellent wear resistance and outstanding high-temperature mechanical stability. It maintains stable working performance and structural integrity under long-term high-temperature service conditions. In addition, the product features high density, efficient thermal conductivity, extremely low vapor pressure and low thermal expansion coefficient, with minimal deformation and performance attenuation in high-temperature, high-pressure and extreme working environments. It is widely applicable in high-temperature furnace accessories, electronic industry, metallurgy, aerospace and other fields.

Sintered tungsten slab is a flat tungsten profile processed by powder metallurgy and integral sintering technology, matching the advanced medium-frequency uniform temperature field sintering process of sintered tungsten rods. The product presents a uniform silver-gray metallic appearance with flat and smooth surface, neat edges and corners, and dense and uniform internal tissue without loose layers, bubbles or impurity inclusions. It is formed by integral high-temperature sintering of high-purity tungsten powder, with reliable structural consistency and excellent flatness, solving the problems of poor uniformity and low stability of traditional welded tungsten plates.

Inheriting the superior characteristics of tungsten materials, sintered tungsten slab has all the core advantages of sintered tungsten rods, with more prominent planar structural stability. It has ultra-high melting point and hardness, strong friction and impact resistance, and can withstand long-term high-temperature oxidation and corrosion. With high bulk density, stable thermal conductivity, low vapor pressure and low thermal expansion coefficient, the slab has excellent dimensional stability at variable temperatures, hardly expanding or deforming in extreme high-temperature environments. Relying on its flat structural advantage and reliable high-temperature performance, it is mainly used as high-temperature furnace lining plates, heat insulation plates, electrode base plates, bearing plates for high-temperature sintering equipment, and key wear-resistant and high-temperature resistant structural parts in precision industrial equipment.
