How is the production process for sintered titanium filter?
The production process of sintered titanium filters involves a number of procedures, which need to be combined with raw material handling, melting, plastic processing and quality control, etc. The following is the integration and analysis of the standardized process:
As the core raw material, need to screen high-purity titanium sponge (Fe ≤ 0.30%, O ≤ 0.25%), some alloys need to add aluminum, molybdenum, niobium and other elements.
Alloy ratio: such as β titanium alloy needs to be mixed by weight percentage (such as Mo 4-7%, Nb 4-6.5%, Al 1-4%).
Titanium sponge and alloy powder are pressed into block electrode by hydraulic press, and welded into long electrode by ion welding.
In a vacuum or inert gas environment, the electrode is melted at 1700-1950 ℃ to remove impurities and form titanium ingots.
Multiple melting: usually repeated 2-3 times to enhance compositional homogeneity (e.g., β-titanium alloy requires 3 melts).
Temperature control: Titanium ingot is heated to 950-1100℃ for open billet forging to break the cast organization and refine the grain.
Multi-directional forging: Improve the organization uniformity by forging in different directions, and reduce the subsequent rolling deformation.
Hot rolling: initial rolling at 900-1000 ℃ to form cylindrical blanks (such as 500mm diameter titanium rods).
Cold rolling: finishing rolling at room temperature to improve the dimensional accuracy (e.g. thin-walled tubes, capillary tubes).
Selection of die forging: open die forging with high loss (15-20% burr), closed die forging requires precise control of the volume of the blank.
Acid washing: use hydrofluoric acid - nitric acid mixture (acid concentration ≤ 6%) to remove the oxide skin, resulting in acid mist (G2) and waste acid residue (S5).
Water washing: remove residual acid and grease, generate oily waste water (W1/W2).
Annealing: 700-800 ℃ annealing to eliminate internal stress, some alloys need to solid solution aging (such as 950 ℃ solid solution + 550 ℃ aging).
Straightening: Correct the shape by straightening machine and generate noise (N5).
Chemical analysis: ICP spectrometer to detect impurities (e.g. Fe, O content). Mechanical test: tensile strength.
Mechanical test: Tensile strength (TA1: 240MPa, TC4: 895MPa), elongation, etc.
Ultrasonic flaw detection (UT): detect internal cracks, pores and other defects.
Polishing (Ra≤0.8μm) or spinning treatment to enhance the finish.
Moisture-proof and shock-proof packaging, generating waste packaging materials (S8).

Frequently Asked Questions (FAQ)
1. What are the main advantages of using a sintered titanium filter?
Sintered titanium filters offer high strength, lightweight construction (density of 4.5g/cm³), excellent corrosion resistance (especially in acids, alkalis, and seawater), superior biocompatibility for medical applications, and high-temperature performance up to 540°C.
2. In which industries are sintered titanium filters and rods applied?
They are widely applied in aerospace (fuselage skeletons, engine blades), healthcare (implants, stents), chemical energy (reactors, cooling systems), marine engineering, automotive manufacturing (lightweight rods, exhaust systems), and sports equipment.
3. How do I select the right titanium rod specification?
Selection is based on diameter: use small diameters (<10mm) for medical devices and precision electrodes; medium diameters (10-100mm) for chemical and marine equipment; and large diameters (>100mm) for heavy machinery and nuclear power systems.
4. Why do titanium rods carry a higher price point than other metals?
The cost is primarily driven by raw materials, as titanium sponge accounts for 60% of the cost. Additionally, complex processing methods like vacuum self-consumption arc melting (VAR) are required to ensure high-performance standards.
5. What is the typical service life of a titanium rod?
In conventional environments, titanium rods can last for more than 20 years. In highly corrosive environments like chemical pipelines, they generally have a service life of 8 to 15 years.
6. What maintenance do titanium rods require?
To preserve their integrity, avoid surface scratches and oil contamination. Clean them regularly with water or neutral detergents. For corrosive environments, it is recommended to test the surface condition every 2 years.
