Titanium Split Ring ,clip ring,swing grip clip ? These? split ring are made of titanium! ? non-magnetic for gear and lashing attachment No Corrosion. This attribute of Titanium is the most significant in the marine sea water environment. Titanium has been used in saltwater applications almost since the discovery of the metal in the 1950's. Industry sources indicate continuing usage of the original Titanium equipment after 30 years of constant saltwater immersion has produced no measurable corrosion. Other saltwater applications with water temperatures as high as 500F has produced the same result: no measurable corrosion. Titanium's corrosion resistance is due to a stable, protective and strongly adherent oxide film. The film forms instantly when Titanium is exposed to a trace of air or water. Cost Savings. Since Titanium will never corrode, you won't be spending your hard earned money for replacement parts that have been destroyed by rust and corrosion. Titanium: "Own it for Life." Strength.
