Sponge titanium is the basic raw material for producing refined titanium. The sponge titanium can be further refined to produce titanium ingot, titanium rod and other metal titanium materials. Titanium powder can be produced by mechanical grinding of sponge titanium. As a coating material, titanium powder is widely used in the surface treatment of mechanical equipment, the treatment of electronic and precision instrument components, and the synthesis of titanium alloy powder with other metals Sponge titanium is a kind of porous, fragile and highly soft titanium metal with high force to weight ratio. Titanium structure has low temperature resistance, low conductivity and corrosion resistance. Sponge titanium is a semi-finished product, which is used to produce titanium ingots. Titanium ingots are used to produce fine titanium products such as plates, strips and rods. It is widely used in aerospace, ships, weapons, chemical industry, petroleum, electric power, light industry, metallurgy, textile, construction, medical treatment, sports, leisure and other industries.
Hongke sponge titanium is mainly produced by magnesium reduction distillation process. In the production process, its refining and purification is carried out by vacuum distillation. The product obtained is loose and fine porous, and looks like a sponge, so it is named. Sponge titanium is a primary product in the whole titanium production. Titanium ingots, i.e. industrial pure titanium, need to be further melted and cast before they can be processed into corresponding titanium materials or titanium alloys.
Crushing method of sponge titanium: different manufacturers have different crushing processes, but the basic principle of crushing is mainly the principle of extrusion or shear crushing.

In addition, sponge titanium also has substandard products with titanium content of more than 90-97%, most of which are used for steelmaking and aluminum alloy casting. At present, Jintai group and other foreign sponge titanium production and sales ranks first in China and is exported to more than 20 countries in the world
