Tungsten copper board file is a file fitter filing of tool steel, steel file sub-flat, round, square, angular, five and a half, flat to flat file also challenge the filing, circle is round file, square is square file, triangular file angle, half semicircle filing, the board filing can also be called flat file.

Tungsten copper support plate means it is used as a key foundation dedicated integrated circuit card module encapsulation material, primarily protects the chip and the role of integrated circuit chips and external interface as in the form of the strip, the surface will be gold-plated gold yellow.

Tungsten copper labtech combines the advantages of tungsten and copper, because of its high thermal conductivity so that electric panels can heat rapidly. Compared to other metal materials, tungsten copper with superior thermal performance, long life, can greatly reduce costs.

15×100×200mm tungsten copper plate with 8mm thickness, width is 100mm, and length is 200mm, general tolerance of thickness is ±0.2mm, length and width tolerance is 0 to +2mm. It can be applied to heavy-duty sliding friction, high-speed and moving solid seals. Various instruments require non-magnetic, low expansion, high elastic modulus, shielding and other special requirements.

10×100×200mm tungsten copper plate with 8mm thickness, width is 100mm, and length is 200mm, general tolerance of thickness is ±0.2mm, length and width tolerance is 0 to +2mm. An important use of high-density tungsten copper plate is as high-temperature components such as gas rudders, nozzles, throat linings, and nose cones that are ablated and washed by high-temperature, high-speed airflow such as rockets and missiles.

8×100×200mm tungsten copper plate with 8mm thickness, width is 100mm, and length is 200mm, general tolerance of thickness is ±0.2mm, length and width tolerance is 0 to +2mm. Which with excellent electrical and thermal conductivity, uniform microstructure, high temperature resistance, high strength, arc erosion resistance and high density.

5×100×200mm tungsten copper plate with 5mm thickness, width is 100mm, and length is 200mm, general tolerance of thickness is ±0.2mm, length and width tolerance is 0 to +2mm. With excellent electrical and thermal conductivity, uniform microstructure, high temperature resistance, high strength, arc erosion resistance and high density.

16×100×100mm tungsten copper plate has a thickness of 16 mm, a width and length of 100 mm, a conventional thickness tolerance of ±0.2 mm, and a length and width tolerance of 0 to +2 mm. As a contact material, it has very good machinability and thermal shock resistance. Due to arcing during contact and breaking, the contact material will rise by several thousand degrees Celsius in a fraction of a second.

10×100×100mm tungsten copper plate has a thickness of 10 mm, a width and a length of 100 mm, a conventional thickness tolerance of ±0.2 mm, and a length and width tolerance of 0 to +2 mm. It not only has excellent mechanical strength, but also has excellent resistance to arc ablation. It is widely used in vacuum electrical contacts, transformer switch contacts and some electric and electric forging industries in practical applications.

CCTV's first large-scale popular science program broadcasts a section on the contents of China's tank armor-piercing projectiles: China's 59-type tank armor-piercing projectile instantly penetrates ten layers of steel plates, with a total wear depth of 1500mm. Therefore, for the most advanced 99A tanks in China, which are superior to the performance of the 59-2 tank, if it is a 125mm tungsten alloy armor-piercing projectile, the piercing depth should be greater than 1500mm.
