Common Grades
TA1: It is an industrial pure titanium. It has good corrosion resistance and certain strength. It is suitable for occasions that require high corrosion resistance，but not extreme strength. Such as general chemical filtration, seawater filtration and other fields.
TA2：It is also a kind of industrial pure titanium. It has high purity, strong corrosion resistance and relatively good strength. It is widely used. It can be used to manufacture titanium mesh filter elements, titanium filter discs, electroplated anode mesh, etc. It is one of the commonly used grades of titanium mesh products in the medical field. Such as titanium mesh systems in vertebral replacement surgery.
TA3：Compared with TA1 and TA2, it has higher strength. But slightly weaker corrosion resistance. It is used in some structural parts or filter components that require higher strength. Such as in some chemical filtration equipment that needs to withstand higher pressure.
GR1：The corresponding grade is pure titanium in the US standard. It is similar to TA1 in the national standard. It has excellent corrosion resistance and biocompatibility. It is commonly used in aerospace, medical equipment, chemical industry and other fields.
GR2：It is an industrial pure titanium grade in the American standard. It is similar to the national standard TA2. It has achieved a good balance in corrosion resistance, strength and processing performance. It has a wide range of applications. Including shipbuilding, petrochemical, electronics and other industries.
R50250：A grade of titanium alloy. It has higher strength and better high temperature resistance. It is often used in high-tech fields such as aerospace, military, and some industrial occasions that require extremely high material performance. Such as structural parts in high temperature environments, high-performance engine parts, etc.
TC4（Ti – 6Al – 4V）：This is one of the most typical titanium alloy grades. It contains 6% aluminum and 4% vanadium. It has excellent comprehensive properties. Including high strength, good toughness, corrosion resistance and machinability. In the aerospace field, it is often used to manufacture aircraft engine parts, landing gear and other key components. In the medical field, it is used to manufacture implantable devices such as artificial joints.
TC10（Ti – 6Al – 6V – 2Sn）：By adding more alloy elements, the strength is further improved. It is suitable for manufacturing structural parts that bear higher loads, such as wing beams of large aircraft.
Density
The density of titanium is typically between 4.51g/cm³-4.54g/cm³.

Material properties
Excellent corrosion resistance: Titanium mesh performs well in a variety of corrosive media. Such as seawater, wet chlorine, chlorite and hypochlorite solutions, nitric acid, chromate metal chlorides and organic salts. A dense, highly adhesive and inert oxide film will form on its surface. Passivation occurs. It can effectively protect the substrate from corrosion.
Good biocompatibility: It will not cause obvious immune response when in contact with human tissues and body fluids. It is suitable for long-term implantation in the medical field. Such as bone defect repair in orthopedic surgery, dental implants and maxillofacial repair in dental surgery, etc.
High strength and low density: It has high strength. It can withstand certain pressure and tension. At the same time, its density is relatively low. It is about 4.5g/cm³. It can be used to manufacture lightweight structural parts in the aerospace field. It can reduce the weight of aircraft. It can also be used to manufacture high-end lightweight sports goods.
Good high temperature resistance: can adapt to high temperature environment. Can be used in high temperature operation scenes. Such as high temperature electric furnace heat treatment support net.
Manufacturing process
Weaving process: titanium wire is interwoven in plain, twill, dense and other weaving methods.
The plain weave has a stable structure. The mesh shape is regular. It is suitable for high-precision filtration.
Twill weave has good flexibility and elasticity. It is suitable for scenes that need to withstand certain deformation.
Stamping process: Use a die to stamp the titanium plate. Produce a titanium mesh with a regular shape and uniform mesh size. It is thicker and has high strength. It is often used for structural materials that withstand greater pressur. Such as building decoration or industrial equipment protection nets.
Laser cutting process: Use high energy density laser beam to cut titanium material. It can produce titanium mesh with complex shapes. It has high cutting accuracy and smooth edges. It is often used in fields with extremely high requirements for shape and accuracy. Such as heat dissipation mesh of electronic equipment.
