In the world of advanced manufacturing, products define efficiency. For over 50 years, Qingdao Bortome Import & Export Co., Ltd. has stood at the center of tungsten carbide (wolfram carbide) development. Established in 1972 and based in the commercial hub of Qingdao, China, the company operates as a wholly-owned subsidiary of Tongyu Heavy Industry Co., Ltd. (Stock Code: 300185)-- a publicly detailed giant and one of China's top 10 cemented carbide producers. Leveraging the robust capacities of its parent company, incorporated with the abundant resources of its subsidiary network, and making the most of Qingdao's calculated location and skill swimming pool, Bortome is devoted to developing a first-rate enterprise concentrating on the research study, design, manufacture, and after-sales solution of a detailed variety of tungsten carbide items.
** A Tradition of Production Excellence **.
Bortome's journey began in 1972, making it one of China's pioneers in tungsten carbide manufacturing. Today, the company runs extensive production areas furnished with cutting edge centers, consisting of two committed sintering furnace workshops. With a total amount of 36 sintering heaters, amongst which are progressed PVA sintering furnaces imported from Germany, the company makes sure consistent thermal performance across every production batch. These advanced systems assure the architectural integrity, density, and homogeneity that are vital to creating premium-quality wolfram carbide products.
** Accuracy Begins with Purity-- The Dust-Free Pressing Workshop **.
A cornerstone of Bortome's quality control is its dust-free pressing workshop. This devoted center plays an essential function in handling the cemented carbide manufacturing process by making sure absolute material purity during the pressing stage. By avoiding impurities and harmful pollutants from infiltrating the item, the workshop safeguards the high criteria required by industries ranging from aerospace to mining. Journalism equipment's ability covers a remarkable array-- from one gram for micro-components to 50 kilos for large commercial parts-- supplying unmatched adaptability to satisfy varied customer requirements.
** Micro‑Level Accuracy Machining **.
With a fleet of 192 machining systems-- consisting of grinders, turrets, milling machines, machining centers, and cutting machines-- Bortome supplies accuracy that rivals the world's best. The company accomplishes ** h5 machining accuracy ** for tungsten carbide rods, a tolerance that ensures best fit and performance in high-speed cutting tools. For mining equipment and oil industry products, surface roughness precision reaches a remarkable ** 0.01 micrometers **, extending element life and decreasing friction in one of the most rough settings. This commitment to micron-level accuracy is what sets Bortome in addition to regular providers.
** Unmatched Mechanical Characteristics-- Compressive, Tensile, and Yield Strength **.
Tungsten carbide is renowned for its remarkable firmness and wear resistance, yet its mechanical strength parameters are just as essential for engineering applications. Bortome's products are crafted to provide superior ** compressive strength **, frequently exceeding 5,000 MPa, making them excellent for tools based on severe stress, such as mining buttons and stamping dies. The ** tensile strength ** of our grades generally varies from 1,500 to 2,500 MPa, ensuring resistance to fracture under drawing pressures, while ** yield strength ** worths are customized to maintain dimensional security under lots. These residential properties are meticulously managed with rigorous sintering cycles and cobalt binder optimization, allowing Bortome to generate custom grades that match or go beyond global standards like ISO K20, P30, and M20.
** Comprehensive Product Portfolio-- Engineered for every single Industry **.
Bortome's comprehensive product schedule covers practically every application where tungsten carbide excels. Below is a thorough introduction of our core offerings:.
** 1. Tungsten Carbide Rods & Solid Carbide Rods **.
As one of China's leading rod manufacturers, Bortome generates solid and coolant‑hole rods in sizes from 2 mm to 50 mm and lengths up to 400 mm. Our rods are available in ground (h5/h6 resistance) and unground versions, with straight or helical coolant holes. They are commonly used for end mills, drills, reamers, and various other rotary cutting tools. Annual production capacity surpasses 1,000 statistics tons, and we provide to significant markets throughout Europe, Americas, Asia, and Australia.
** 2. Tungsten Carbide Buttons & Inserts for Mining and Construction **.
Our ** YG6 ** and ** YG8 ** grades are the industry requirement for rock drilling, oil drilling, and coal mining. YG6 (WC‑6% Co) provides a solidity ≥ 89.5 HRA, flexing strength ≥ 1,900 MPa, and effect durability of 2.6 J/cm TWO-- supplying 40% greater machining performance on cast iron compared to high‑speed steel and extending tool life by 5 times over traditional steel passes away. YG8 (WC‑8% Co), tungsten carbide seal rings to ISO K20, attains 89-- 90 HRA firmness, 1,500 MPa bending strength, and maintains high hardness also at 900-- 1,000 ° C, making it excellent for heavy‑duty percussion drilling and high‑speed milling of unpleasant materials.
