Titanium

Introduction: Materials Driving the Future of Technology

The rapid growth of the global semiconductor and display industries is fueled by the rise of cutting-edge technologies like smartphones, autonomous vehicles, artificial intelligence (AI), cloud computing, and the Internet of Things (IoT). These advancements have triggered soaring demand for ultra-fine process technologies and highly integrated circuits. In response, the performance expectations for metal materials used in high-tech manufacturing equipment have reached new heights.


High-Performance Materials for Harsh Processing Environments

Semiconductor and display manufacturing typically occurs in extreme environments—high temperature, high pressure, and exposure to strong acids, bases, and plasma. As a result, materials used for internal components, chambers, gas injection nozzles, and piping must withstand harsh conditions while maintaining dimensional stability and chemical integrity.

Titanium (Ti) alloys and nickel (Ni)-based alloys are among the most reliable metals in this domain. Titanium’s lightweight structure, high corrosion resistance, and strength make it ideal for plasma etching, chemical vapor deposition (CVD), and wet etching processes. Titanium plates, tubes, and pipes minimize metal ion contamination and deliver low chemical reactivity, making them essential to precision semiconductor applications.

Nickel-based alloys such as Inconel, Hastelloy, and Monel offer excellent resistance to oxidation, corrosion, and high temperatures. These alloys are widely applied in high-heat zones of semiconductor and display systems, gas treatment units, and exhaust systems. Particularly, Hastelloy C-22 and C-276 are highly resistant to aggressive etching gases and halogen-based chemicals, making them vital to the fabrication of advanced chips.


Strengthening Supply Chain Independence Through Localization

Historically, high-performance corrosion-resistant alloys for semiconductor applications were imported from countries like Japan, the U.S., and EU nations. However, with supply chains being realigned and calls for domestic material sovereignty growing, South Korea is accelerating localization of titanium and nickel alloys.

Through focused R&D in high-purity refining, custom alloy development, and precision machining, Korean companies and research institutions are replacing imported materials with high-quality domestic alternatives. This effort not only supports the semiconductor industry’s stable operation but also enhances the country's global competitiveness in material technology.

Domestic suppliers are collaborating with specialized processors capable of precision machining corrosion-resistant alloys to meet exact industry requirements. As semiconductors continue to evolve toward higher miniaturization, integration, and speed, the role of advanced titanium and nickel alloys will grow even more significant.

Dong-A Special Metals is proud to contribute to this critical supply chain by offering precision-treated, recycled titanium and nickel-based alloy materials tailored for semiconductor and display applications. For Korean CNC and materials companies seeking reliable, sustainable alloy solutions, Dong-A Special Metals is a ready partner in resource circulation and technological independence.
