In the world of advanced manufacturing, products define performance. For over half a century, Qingdao Bortome Import & Export Co., Ltd. has stood at the center of tungsten carbide (wolfram carbide) advancement. Established in 1972 and based in the commercial hub of Qingdao, China, the company runs as a wholly-owned subsidiary of Tongyu Heavy Industry Co., Ltd. (Stock Code: 300185)– an openly noted giant and one of China’s leading 10 cemented carbide producers. Leveraging the robust capacities of its parent company, incorporated with the rich resources of its subsidiary network, and maximizing Qingdao’s calculated location and talent pool, Bortome is committed to developing a first-rate venture concentrating on the study, design, manufacture, and after-sales solution of a detailed variety of tungsten carbide products.
** A Tradition of Manufacturing Quality **.
Bortome’s trip started in 1972, making it one of China’s leaders in tungsten carbide production. Today, the company runs large production areas furnished with modern centers, including two dedicated sintering heater workshops. With a total amount of 36 sintering furnaces, among which are progressed PVA sintering furnaces imported from Germany, the company guarantees regular thermal efficiency throughout every manufacturing set. These innovative systems guarantee the architectural integrity, density, and homogeneity that are critical to producing premium-quality wolfram carbide products.

A foundation of Bortome’s quality assurance is its dust-free pushing workshop. This specialized center plays a critical role in handling the cemented carbide production procedure by ensuring absolute product purity during the pressing stage. By preventing impurities and destructive impurities from penetrating the item, the workshop safeguards the high criteria demanded by industries varying from aerospace to mining. Journalism equipment’s capability extends an outstanding variety– from one gram for micro-components to 50 kgs for large-scale industrial parts– using unmatched adaptability to fulfill varied customer demands.
** Micro‑Level Accuracy Machining **.
With a fleet of 192 machining devices– consisting of grinders, lathes, milling machines, machining centers, and cutting machines– Bortome supplies precision that rivals the globe’s finest. The company achieves ** h5 machining accuracy ** for tungsten carbide rods, a tolerance that makes certain perfect fit and efficiency in high-speed cutting tools. For mining equipment and oil industry materials, surface roughness accuracy reaches an extraordinary ** 0.01 micrometers **, prolonging part life and minimizing friction in the most abrasive atmospheres. This commitment to micron-level precision is what sets Bortome in addition to common suppliers.
** Unmatched Mechanical Features– Compressive, Tensile, and Yield Strength **.
Tungsten carbide is renowned for its phenomenal firmness and wear resistance, yet its mechanical strength specifications are just as critical for design applications. Bortome’s products are crafted to deliver exceptional ** compressive strength **, usually going beyond 5,000 MPa, making them perfect for tools subjected to extreme pressure, such as mining buttons and stamping passes away. The ** tensile strength ** of our grades usually ranges from 1,500 to 2,500 MPa, making sure resistance to crack under pulling pressures, while ** yield strength ** worths are tailored to maintain dimensional stability under lots. These properties are carefully regulated with strict sintering cycles and cobalt binder optimization, allowing Bortome to generate custom grades that match or go beyond worldwide criteria like ISO K20, P30, and M20.
** Comprehensive Item Portfolio– Engineered for each Industry **.
Bortome’s substantial item lineup covers practically every application where tungsten carbide succeeds. Below is a detailed review of our core offerings:.
** 1. Tungsten Carbide Rods & Solid Carbide Rods **.
As one of China’s leading rod manufacturers, Bortome produces solid and coolant‑hole rods in diameters from 2 mm to 50 mm and lengths approximately 400 mm. Our rods are readily available in ground (h5/h6 resistance) and unground versions, with straight or helical coolant openings. They are extensively utilized for end mills, drills, reamers, and other rotary cutting tools. Annual production capability goes beyond 1,000 statistics tons, and we supply to significant markets across 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, bending strength ≥ 1,900 MPa, and effect toughness of 2.6 J/cm TWO– providing 40% higher machining effectiveness on cast iron contrasted to high‑speed steel and extending tool life by five times over traditional steel dies. YG8 (WC‑8% Co), equal to ISO K20, accomplishes 89– 90 HRA firmness, 1,500 MPa flexing strength, and preserves high firmness also at 900– 1,000 ° C, making it suitable for heavy‑duty percussion drilling and high‑speed milling of rough materials.
