Titanium Properties and Characteristics - ThoughtCo
31/10/2019· Alloys containing titanium are known for their high strength, low weight, and exceptional corrosion resistance. Despite being as strong as steel , titanium is about 40% lighter in weight. This, along with its resistance to cavitation (rapid pressure changes, that cause shock waves, which can weaken or damage metal over time) and erosion, makes it an essential structural metal for aerospace
