📌 Why Choose Qingdao Bortome?

Best For: Large-scale distributors and heavy industry buyers (Mining/Oil & Gas) seeking a financially stable partner capable of high-volume, consistent production.

  • Backed by Public Listed Stability: Security is a major concern when selecting an overseas OEM partner. Qingdao Bortome is a wholly-owned subsidiary of Tongyu Heavy Industry (Stock Code: 300185). This corporate backing ensures robust financial health, minimized supply chain risks, and long-term operational stability. Compared to smaller, independent workshops, Bortome is a safer choice for large, recurring contracts.
  • Advanced "Gradient Alloy" for Mining: For buyers in the drilling and mining sectors, durability is currency. Collaborating with American experts, Bortome has developed a proprietary Gradient Alloy technology. This innovation significantly enhances the wear resistance of their carbide buttons, extending service life by approximately 30%-50%. This directly translates to reduced downtime and lower operational costs for end-users in rock drilling applications.
  • German-Standard Sintering Consistency: To compete with top-tier global brands, they have invested heavily in infrastructure, utilizing imported German PVA sintering furnaces and a dust-free pressing workshop (capable of 1g to 50kg pressing). This setup ensures metallurgical purity and structural uniformity. Their internal data suggests product performance and lifespan reach 90-97% of leading international brands, offering an excellent price-performance ratio.
  • Precision Finishing & Stellite Capabilities: Beyond standard carbide, they possess a distinct advantage in advanced materials and finishing. With 192 sets of machining equipment, they deliver ground rods to h5/h6 tolerance and mirror-finish parts with 0.01µm roughness. Uniquely, they also supply Stellite alloys for extreme heat and corrosion environments (Aerospace, Nuclear), a capability that separates them from general carbide producers.
