Latest Patents

One of Maehara's latest patents is focused on a copper alloy and the process for producing the same. This copper alloy consists of two or more elements, including chromium (Cr), titanium (Ti), and zirconium (Zr), with the balance being copper (Cu) and impurities. The patent outlines a specific relationship between the total number N and the diameter X, which must satisfy a defined formula. The alloy is produced by cooling a bloom, slab, billet, or ingot from its casting temperature to 450°C at a cooling rate of 0.5°C/s or more. Following this cooling process, the alloy undergoes working at temperatures of 600°C or lower, along with a heat treatment that involves holding for at least 30 seconds in a temperature range of 150 to 750°C. This process is ideally repeated multiple times to achieve the desired properties.
