Title: Isao Hosokawa: Innovator in Metal and Alloy Manufacturing
Introduction
Isao Hosokawa is a notable inventor based in Shimonoseki, Japan. He has made significant contributions to the field of metal and alloy manufacturing, holding a total of 3 patents. His innovative approaches have led to advancements in the quality and efficiency of metal production processes.
Latest Patents
One of Hosokawa's latest patents is a manufacturing method of metal or alloy. This method involves measuring the conductivity distribution on the cross-section of metal or alloy using an eddy current type conductivity meter. A conductivity distribution contour map is then prepared, which allows for the analysis of the heat history of an ingot and the segregation of added elements. This process enables the re-establishment of melting and/or casting conditions, providing quick assessment results. Consequently, it helps eliminate metal or alloy ingots that may produce poor quality products in subsequent steps. This method is particularly beneficial in the manufacturing of copper precipitation hardening alloys, resulting in more sound ingots and better suitability for further processing.
Another significant patent by Hosokawa is for a copper alloy that exhibits excellent migration resistance. This alloy comprises 0.05 to 0.20% by weight of Fe, 0.02 to 0.05% by weight of P, 1.0 to 5.0% by weight of Zn, less than 2.5% by weight of Sn, with the substantial balance being Cu and impurities. The copper alloy developed through this invention demonstrates migration resistance comparable to brass, along with superior resistance to stress corrosion cracking and higher strength than both pure copper and other copper alloys.
