Abstract: Proposed is a highly corrosion-resistant aluminum alloy including one or more components selected from among 0.1 wt. % or less (except for 0 wt. %) of Cu, 0.15 wt. % or less (except for 0 wt. %) of Si, 0.2 wt. % or less (except for 0 wt. %) of Fe, 0.9 to 1.5 wt. % of Mn, 0.03 to 0.15 wt. % of Ti, 0.03 to 0.15 wt. % of Cr, and 0.03 to 0.15 wt. % of Zr, and the remaining proportion of aluminum (Al) and unavoidable impurities. The highly corrosion-resistant aluminum alloy contains Ti, Cr, and Zr in a predetermined weight ratio or in equal weight percentages (wt. %), thereby exhibiting improved corrosion resistance in a saline water environment while exhibiting excellent levels in tensile strength and yield strength.

Abstract: Disclosed herein is a method of manufacturing a container for absorbing fluid shock or mechanical shock. The method includes preparing a raw material pipe, forming a coupling pipe by reducing a diameter of at least one side of the raw material pipe, and forming an inner circumference of the coupling pipe and bending it. Accordingly, a container body and a coupling pipe coupled to at least one side of the container body are integrated together, so that an additional process for coupling the container body with the coupling pipe is not required, and thus the cost of production is reduced.
