In the world of advanced manufacturing, materials define efficiency. For over half a century, Qingdao Bortome Import & Export Co., Ltd. has stood at the forefront of tungsten carbide (wolfram carbide) advancement. Established in 1972 and based in the industrial hub of Qingdao, China, the company runs as a wholly-owned subsidiary of Tongyu Heavy Industry Co., Ltd. (Stock Code: 300185)– a publicly detailed giant and among China’s top ten cemented carbide producers. Leveraging the robust abilities of its parent company, integrated with the rich sources of its subsidiary network, and making the most of Qingdao’s critical place and skill pool, Bortome is devoted to developing a first-rate business concentrating on the study, design, manufacture, and after-sales solution of a detailed variety of tungsten carbide products.
** A Tradition of Production Excellence **.
Bortome’s trip began in 1972, making it among China’s pioneers in tungsten carbide manufacturing. Today, the company operates large production areas furnished with cutting edge facilities, consisting of two committed sintering heater workshops. With a total amount of 36 sintering furnaces, among which are advanced PVA sintering heaters imported from Germany, the company makes sure consistent thermal performance throughout every production set. These advanced systems assure the structural stability, thickness, and homogeneity that are important to generating premium-quality wolfram carbide items.
** Precision Begins with Purity– The Dust-Free Pressing Workshop **.
A keystone of Bortome’s quality control is its dust-free pressing workshop. This specialized facility plays a pivotal duty in handling the cemented carbide manufacturing procedure by making certain absolute material purity throughout journalism stage. By protecting against impurities and damaging pollutants from infiltrating the item, the workshop safeguards the high criteria required by industries ranging from aerospace to mining. The pressing equipment’s capability extends a remarkable array– from one gram for micro-components to 50 kgs for large-scale industrial parts– offering unmatched adaptability to satisfy varied client demands.
** Micro‑Level Precision 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 ideal. The company attains ** h5 machining accuracy ** for tungsten carbide rods, a resistance that ensures best fit and performance 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 reducing friction in the most rough atmospheres. This dedication to micron-level accuracy is what establishes Bortome in addition to normal providers.
** Unmatched Mechanical Residences– Compressive, Tensile, and Yield Strength **.
Tungsten carbide is renowned for its amazing hardness and wear resistance, yet its mechanical strength specifications are similarly vital for design applications. Bortome’s products are crafted to deliver remarkable ** compressive strength **, frequently surpassing 5,000 MPa, making them ideal for tools subjected to severe stress, such as mining buttons and marking passes away. The ** tensile strength ** of our grades usually varies from 1,500 to 2,500 MPa, making certain resistance to fracture under pulling pressures, while ** yield strength ** worths are tailored to maintain dimensional stability under tons. These properties are carefully controlled via stringent sintering cycles and cobalt binder optimization, enabling Bortome to create custom grades that match or surpass international criteria like ISO K20, P30, and M20.
** Comprehensive Product Portfolio– Engineered for each Industry **.
Bortome’s extensive item schedule covers practically every application where tungsten carbide excels. Below is a thorough overview of our core offerings:.
** 1. Tungsten Carbide Rods & Solid Carbide Rods **.
As one of China’s leading rod makers, Bortome generates solid and coolant‑hole rods in sizes from 2 mm to 50 mm and lengths as much as 400 mm. Our rods are offered in ground (h5/h6 resistance) and unground variations, with straight or helical coolant openings. They are widely utilized for end mills, drills, reamers, and other rotary cutting tools. Annual production capability goes beyond 1,000 statistics tons, and we provide to major 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, flexing strength ≥ 1,900 MPa, and impact strength of 2.6 J/cm ²– delivering 40% higher machining efficiency on cast iron compared to high‑speed steel and prolonging tool life by 5 times over traditional steel dies. YG8 (WC‑8% Co), comparable to ISO K20, achieves 89– 90 HRA solidity, 1,500 MPa flexing strength, and maintains high hardness even at 900– 1,000 ° C, making it optimal for heavy‑duty percussion drilling and high‑speed milling of unpleasant materials.
** 3. Tungsten Carbide EDM Blocks **.
Utilized extensively in stamping molds and electrical discharge machining, our EDM blocks offer superb electric conductivity and wear resistance. They are precision‑ground to limited resistances, guaranteeing reliable efficiency in high‑volume manufacturing.
** 4. Tungsten Carbide Plates, Strips, Sheets, and Square Bars **.
Offered in custom dimensions, these flat products act as wear plates, overview rails, and substrates for cutting inserts. Our plates are sintered with consistent density to lessen bending, and we offer both basic and custom sizes.
