Latest Patents
Ishizaka holds a patent for an aluminum alloy pipe with superior corrosion resistance and processability. This patent describes an aluminum alloy pipe produced by porthole extrusion, which includes magnesium at a concentration equal to or higher than 0.7% and lower than 1.5%. Additionally, titanium is included at a concentration higher than 0% and equal to or lower than 0.15%. The balance of the alloy consists of aluminum and unavoidable impurities, with specific limits set for elements such as silicon, iron, copper, manganese, chromium, and zinc. The design ensures that the difference between the maximum and minimum magnesium concentration in the lengthwise direction of the pipe is 0.2% or lower, while the average crystal grain size in a cross-section perpendicular to the lengthwise direction is 300 µm or smaller. This innovation results in an aluminum alloy pipe that exhibits excellent strength, corrosion resistance, and processability, making it ideal for piping or hose joints.
