Aluminum oxide dispersion strengthened copper (ODS)
Aluminum oxide dispersion strengthened copper (ODS) is a conductive material with heat resistance that resists softening even at temperatures of 800℃ Celsius compared to other copper alloys and high conductivity of over IACS 80%. Since ODS has high strength and high conductivity characteristics that are contrary to other copper alloys, it has been used as electrode materials for resistance welding and spot welding of electric vehicles, relay contacts, various electronic parts such as heat-resistant substrates, and reinforcing materials.
Our strength lies in plastic work technology of aluminum oxide dispersion strengthened copper (ODS). Various sizes can be processed from large diameter to small diameter and irregular shape.

Alumina-dispersed strengthened copper (ODS) is a metallic material with excellent high-temperature strength and resistance to softening
Ideal for thermal management components and highly resistant to high-current and high-temperature environments
Comparison of Material Properties Between ODS and Copper Materials
ODS materials (oxide dispersion-strengthened alloys) are alloys in which fine oxides (such as aluminum oxide and titanium oxide) are uniformly dispersed in copper.
Unlike beryllium copper, chromium copper, and oxygen-free copper (which has extremely low impurities), ODS alloys maintain high electrical conductivity while excelling in high-temperature strength, corrosion resistance, and creep properties. Specifically, while beryllium copper is expensive, chromium copper excels in hardness and heat resistance but softens at higher temperatures than ODS, and oxygen-free copper excels in workability and thermal conductivity, ODS offers even higher strength at elevated temperatures and superior heat resistance, making it highly reliable and suitable for electrical conductive components.
Contributing to next-generation fields through miniaturization, weight reduction, irregular shapes, and cladding
High-strength copper enables thinner and smaller materials while delivering performance equivalent to oxygen-free copper, contributing to cost reduction and the miniaturization and weight reduction of products. Leveraging our plastic forming technology, we manufacture a wide range of ODS pipe and bar materials, from large and small diameters to irregular shapes. We contribute to the development and application of various structural and functional materials used in harsh environments across next-generation energy fields (nuclear power, fuel cells, etc.), automotive (resistance welding electrodes), aerospace, and high-performance electronic components.

New Possibilities Opened by Alumina-Dispersed Strengthened Copper
The alumina-dispersed reinforced copper we propose offers a new alternative to the limitations of conventional materials. By dispersing nano-sized alumina particles within pure copper, we have achieved "superior heat resistance" and "mechanical strength" while maintaining "high electrical conductivity" even at elevated temperatures. This redefines the balance of performance characteristics that was difficult to achieve with existing copper alloys.
Key Properties and Applications of Alumina-Dispersed Strengthened Copper
Exceptional Heat Resistance
Alumina-dispersed reinforced copper maintains its strength even in high-temperature environments and resists degradation from oxidation. This enables it to sustain its planned service life over extended periods, making it ideal for enhancing the durability of components exposed to heat in energy applications and other fields.
Maintenance of thermal conductivity and electrical conductivity
Possessing excellent conductivity equivalent to pure copper, it maintains the ability for heat generated within the material to move smoothly from high-temperature areas to low-temperature areas. It is suitable for applications requiring efficient thermal management, such as jet engine components exposed to high temperatures, and for materials that need to maintain electrical conductivity even at high temperatures, such as heat sinks and electronic components.
Excellent wear resistance
Reinforced with nano-alumina particles, it offers high wear resistance and contributes to extended component life. It is widely used as an electrode for spot welding in EVs, where low thermal softening and wear resistance are essential.
It extends the lifespan of aircraft components exposed to high temperatures and pressures, as well as parts resistant to wear in high-temperature fluids and corrosive environments within chemical plants. This enhances the durability and reliability of equipment operating in harsh conditions.
