The titanium melted only from titanium sponge is known as titanium grade 1, which is considered the most pure grade. When titanium sponge is mixed with titanium fragments, the amount of oxygen (O 2) and iron (Fe) increases and titanium becomes harder. The more fragments are added, the harder the titanium becomes (titanium grades 2, 3 and 4).

In addition to its attractive high strength-to-density characteristics for aerospace use, titanium's exceptional corrosion
Titanium sponge with slight iron contamination can be utilized as a raw material for the production of titanium and its alloy ingots. However, titanium sponge scrap with heavy iron contamination (generally several percent) cannot be utilized for titanium ingot production because the iron impurity in the ingot is difficult to dilute and homogenize.
