The lightest, strongest and cheapest metal for forging is Titanium. Titanium is a silvery-white metal that has excellent corrosion resistance and strength. It can be formed into alloys with other metals, including stainless steel, to create a wide range of materials that are both strong and corrosion-resistant
Titanium has the highest strength-to-weight ratio of any metal in its metallic state. Its ability to form alloys makes it a good choice for use in applications that require high strength but also need to be lightweight or inexpensive.
