Latest Patents

Matsunaga's latest patents focus on innovative alloys designed for use in exhaust valves. The first patent describes an alloy that consists of C: 0.01-0.15%, Si ≤ 2.0%, Mn ≤ 0.5%, Cr: 15-25%, Mo: 0.4-3.1%, and W: 0.2-3.8%. This alloy is engineered to ensure that (Mo + 1/2W) is between 0.5 to 5.0%, with Nb + Ta ranging from 0.3-3.0%, Ti from 1.5-3.5%, Al from 0.5-2.5%, B from 0.001-0.02%, Fe ≤ 5%, and the balance being Ni or Ni + Co. The second patent also focuses on alloys for exhaust valves, detailing a composition that includes 0.01-0.15% of C, not more than 2.0% of Si, not more than 2.5% of Mn, 53-65% of Ni, 15-25% of Cr, 0.3-3.0% of Nb, 2.0-3.5% of Ti, 0.2-1.5% of Al, and 0.001-0.020% of B, with the remainder being substantially Fe. This innovative approach to alloy composition aims to improve the efficiency and longevity of exhaust valves in automotive applications.
