Demand Rises for Heat-Resistant Nickel Alloys in Electronics and Industrial Equipment

As electronic devices and industrial equipment become smaller and more powerful, heat generation increases significantly. If not controlled properly, this heat can cause performance drops, shorten lifespan, or even trigger fires. This challenge is driving demand for high-performance metal materials with excellent heat dissipation properties. Among these, nickel-based alloys stand out for their stable performance at high temperatures.

Nickel-based alloys offer outstanding oxidation resistance, mechanical strength, and thermal conductivity. Alloys such as Inconel and Hastelloy retain their physical integrity at temperatures ranging from several hundred to nearly 1,000°C. This makes them ideal for heat sinks, heat spreaders, and cooling blocks used in servers, electric vehicles, and power semiconductors. Their low thermal expansion and superior creep resistance enhance durability under thermal stress.


Applications in Electronics, Aerospace, and Chemical Industries

Inconel alloys, long used in aerospace and power plants, are now applied in heat dissipation for data centers and high-power electronics. These include server cooling housings, heat-dissipation ducts, and high-temperature drive module frames. Their ability to resist deformation and cracking under repeated thermal cycling ensures long-term durability in demanding environments.

Meanwhile, Hastelloy C-22 and C-276, nickel-molybdenum-based corrosion-resistant alloys, provide excellent high-temperature stability and are resistant to chemicals such as chlorine and sulfur. These properties make Hastelloy ideal for semiconductor manufacturing equipment, chemical process lines, and any heat dissipation application requiring both thermal and chemical resistance.

Dong-A Special Metals processes nickel-based alloys into plates, strips, foils, and complex housings. Thin, wide plates are especially useful for heat spreaders and cooling panels due to their efficient heat dispersion. The materials are easily formed into complex geometries, making them suitable for vehicle inverter housings and server cooling frames.

Beyond performance, these alloys also support sustainable practices. Containing valuable rare metals like nickel and molybdenum, they are ideal for high-purity recycling. Dong-A Special Metals actively participates in recycling end-of-life heat dissipation components. By refining and purifying scrap, the company contributes to carbon neutrality and strengthens the domestic alloy supply chain through a recycling-based system.
