Latest Patents

Kei Ito holds a patent for a brass alloy and processed part that excels in recyclability and corrosion resistance. This invention avoids the addition of bismuth (Bi) and silicon (Si), while ensuring that machinability is maintained and the inclusion of lead is prevented. The brass alloy comprises at least 58.0 to 63.0 mass % of copper (Cu), 1.0 to 2.0 mass % of tin (Sn), and 0.05 to 0.29 mass % of antimony (Sb), with the remainder made up of zinc (Zn) and unavoidable impurities. This invention improves stress corrosion crack resistance and machinability by including 0.05 to 1.5 mass % of nickel (Ni) to enhance the interaction between Ni and Sb. Additionally, 0.05 to 0.2 mass % of phosphorus (P) is included to improve anti-dezincification properties.
