In this interview with Metalverse Taiwanalloy gives an insight into their current technology break throughs and collaborations.

Metalverse: Taiwanalloy emphasizes a full value chain from raw material preparation to molding and processing in tungsten carbide. How do you manage the heat-treatment and sintering steps to ensure consistent microstructure and mechanical properties across such a vertically integrated process?

Taiwanalloy: In the tungsten carbide production process, quality control involves cross-checking data at each stage and adjusting production parameters based on the desired product characteristics. We implement strict control beginning at the powder stage, continuing through forming and sintering, and concluding with thorough product inspections to collect performance data. To ensure uniform quality, we place test samples in every sintering batch and conduct complete inspections on them after processing. This helps verify consistency and quality across all stages of production. It’s a comprehensive approach—we’re not just controlling one step, but the entire chain.

Metalverse: Your company collaborates with universities and research institutes on R&D. What new alloy systems or heat-treatment innovations are you developing to push the limits of hardness, toughness, or wear resistance in tungsten carbide products?

Taiwanalloy: We are committed to the development of new materials and the resolution of end-user challenges. This is where our industry-university-institute alliance really shows its value. We’ve successfully developed a composite alloy tungsten steel, and we’re proud to say we’ve successfully filed an invention patent application for it. This represents a significant innovation in complex alloys and demonstrates our core industrial technology capabilities.

Metalverse: You offer customized products with diameters up to 250 mm, which are quite substantial. What thermal challenges—such as temperature gradients, shrinkage, or residual stress—do you face with these large geometries, and how do you control them in the sintering and HIP stages?

Taiwanalloy: This is particularly relevant right now. Due to China’s tungsten export restrictions in 2025, we’ve received a significant number of new requests for custom products. When responding to new product requirements, we begin by thoroughly understanding the end-user’s application needs. We then produce samples and use detailed inspection results, along with recorded production parameters, to control each stage of the process and ensure the final product meets the required quality standards. Our approach is very methodical—understand the application, produce test samples, inspect rigorously, document everything, and use that data to control the full production process.

Metalverse: Speaking of process control, how do you monitor and control temperature uniformity and atmosphere in your furnaces during sintering, especially for complex or large geometries?

Taiwanalloy: With many years of production experience—40 years, in fact—we ensure product quality and yield through meticulous documentation of production parameters. We’ve integrated ERP systems into the manufacturing process, which allows us to track and control every parameter digitally. We’re also continuously advancing our smart equipment capabilities and strictly implementing inspection procedures at every stage. It’s this combination of experience, documentation, digital systems, and modern equipment that allows us to maintain the temperature uniformity and atmospheric control needed for consistent results.

Metalverse: As sustainability becomes more important globally, how are you optimizing heat-treatment cycles—for example, energy consumption and cooling rates—without compromising performance? What advances do you see ahead in low-energy thermal processing for carbide-based materials?

Taiwanalloy: Under the promotion of ESG concepts, energy-saving production methods are definitely the direction of our efforts. We see two main pathways for improvement: equipment upgrades in the sintering process and changes in tungsten carbide formulas. Both can significantly improve production energy consumption issues. The equipment side is more straightforward—newer furnaces are simply more energy-efficient with better insulation and control systems. But the formula development is equally important. By optimizing the alloy composition, we can sometimes reduce sintering temperatures or shorten cycle times without compromising the final properties. This is where our R&D collaboration with universities really pays off.

Metalverse: Looking at the bigger picture, how does Taiwanalloy position itself in the global tungsten carbide market, particularly as a 100% Taiwan-made manufacturer?

Taiwanalloy: Our philosophy is “there is no best, only better”—this is our entrepreneurial spirit. We’re rooted in Taiwan but based in the world. We want to showcase Taiwan to the world and demonstrate the progress of Taiwan’s industrial technology. With the recent export restrictions from China, there’s been increased global interest in alternative sources for high-quality tungsten carbide. We’re positioned to meet that demand with our vertically integrated capabilities, our precision customization, and our round-the-clock production. We cooperate with universities to develop new technologies and study the application needs of our customers to form an effective link between production and sales services.

Metalverse: You mentioned nurturing future talents. How important is that to Taiwanalloy’s long-term strategy?

Taiwanalloy: It’s fundamental to our corporate social responsibility. We provide support to related departments at universities and colleges with practical experience and resources to cultivate the future talents of our nation. We encourage our employees to pursue further education and create a lifelong learning blueprint for each of them. In the future, we’ll continue to make good use of resources from industry, government, and academia to actively cooperate in developing advanced tungsten carbide alloy core technologies, planning personnel training, and refining equipment. This will increase our production capacity and boost the international competitiveness of Taiwan’s metal industry.

Metalverse: Thank you for sharing your insights on tungsten carbide production and Taiwanalloy’s vision for the future.

Taiwanalloy: Thank you. We’re committed to refinement, bravery, and stamina in everything we do. That’s what “Made in Taiwan” means to us.
