Titanium sponge is an elemental form of titanium that typically appears as light grey particles or a sponge-like mass. It serves as the fundamental raw material for the production of titanium materials, titanium powder, and other titanium products. Sponge titanium is obtained by transforming titanium ore into titanium tetrachloride, which is then reacted with metallic magnesium to yield a porous, sponge-like mass. During the reduction and distillation process, impurities can be introduced into the titanium sponge lump due to a variety of factors, including temperature, pressure, furnace condition, and segregation. According to the Chinese standard GB/T 2524, titanium sponges can be classified into seven grades, ranging from MHT 95 to MHT 200, with the number referring to the Brinell hardness maximum value. The general purity (%) quality is 98.5 to 99.8, and the impurity element oxygen quality (%) ranges from 0.05 to 0.30. The hardness (HB) of sponge titanium ranges from 95 to 200. Features High strength-to-weight ratio: Titanium sponge is perfect for use in aerospace and military applications where weight reduction is important because of its high strength-to-weight ratio. Excellent corrosion resistance: Titanium sponge is highly resistant to corrosion, even in harsh environments. Biocompatibility: Titanium sponge is biocompatible, making it an ideal material for use in medical implants and devices. Heat resistance: Titanium sponge has a high melting point and is highly resistant to heat, making it ideal for use in high-temperature applications. Applications Defense and aerospace: Due to its superior corrosion resistance and high strength-to-weight ratio, the titanium sponge is frequently utilized in the defense and aerospace industries. Chemical and Petrochemical: Titanium sponge is used in the chemical and petrochemical industries due to its excellent corrosion resistance. It is used in heat exchangers, pressure vessels, and reactors. Medical: Titanium sponge is biocompatible, making it ideal for use in medical implants and devices, such as dental implants, joint replacements, and pacemakers. Sports equipment: Titanium sponge is used in sports equipment, such as golf clubs, tennis rackets, and bicycle frames, due to its high strength-to-weight ratio. Jewelry: Titanium sponge is used in jewelry making due to its unique properties, such as its light weight and corrosion resistance.
