Research and development on high-entropy alloys is being actively conducted worldwide, as the properties of the metals and precious metals contained in these alloys can simultaneously produce properties such as high strength and high heat resistance, as well as the possibility of creating new properties.</p> </section> <section id="block02" class="content-block"> <h2 class="ttl-common">Properties of High Entropy Alloy Powder</h2> <h3 class="sub-ttl"><span class="ico">■</span>High strength and high heat resistance; micro-order alloy powders that are easy to use in industrial applications</h3> <p>The precious metal alloy powders in this product are alloys composed only of five or more precious metal elements that maintain the corrosion resistance, electrical conductivity, and other excellent properties of precious metals. They are micro-order<sup>2</sup> alloy powders that are easy to use in industrial applications.</p> <p>Unlike conventional nano-order precious metal high-entropy alloys, micro-order alloys are stable as alloys due to their large crystallite size, and they satisfy the original requirements of alloys, such as improved mechanical strength, corrosion resistance, and controlled thermal expansion. They are also expected to contribute to the improvement of the functions and properties of precious metal alloys, whose properties vary greatly depending on the composition ratio of the alloy.</p> <p>The precious metal alloy in this product is in powder form, and in addition to modeling using a 3D printer and rod forming (forming rod-shaped material by solidifying powder), it can also be used in paste form, which is often used in various circuits and sensors. Furthermore, the high strength and high heat resistance properties of high-entropy alloys are expected to be utilized in catalysts and conductive films that require high durability, among other applications.</p> <p class="bordersup"><sup>2</sup> Order: A term used in physics, engineering, and other fields to roughly express the magnitude of a number.
