Titanium 6Al-6V-2Sn (also known as 6-6-2 Titanium) is an alpha-beta alloy with superior strength, solid corrosion resistance, and medium welding and fabrication ability which make it an excellent metal for rocket and aircraft casing and artillery parts. For improved ductility and strength, Ti 6-6-2 can be heat treated to desired attributes. Standard specifications for titanium 6Al-6V-2Sn include UNS R56620, AMS 4919 and more.
