Introduction to the Use and Process of Titanium Processing Parts!
Titanium processing parts are made from industrial pure titanium or titanium alloy as raw materials, forged CNC、 Components made by welding, surface treatment and other processes have the core advantages of being light, strong, corrosion-resistant, and biocompatible, and are used in fields such as aerospace, chemical and marine industries, energy and power.
1、 Material classification and grade
1. Industrial pure titanium (TA1/TA2/TA3/TA4, Grade 1-4)
Characteristics: Purity ≥ 99.5%, extremely strong corrosion resistance, good plasticity, low strength, excellent weldability.
Usage: Chemical pipelines/valves, seawater desalination equipment, pressure vessels, decorative parts.
2. Alpha titanium alloys (TA6/TA7/TA15, etc.)
Characteristics: High temperature resistance, good welding performance, strong creep resistance, long-term stability at 400-500 ℃.
Usage: High temperature components for aircraft engines, heat exchangers for nuclear reactors, and high-temperature welded structural components.
3. Alpha - β titanium alloys (TC4/TC11/TC18, etc.)
TC4 (Ti-6Al-4V): accounts for more than 50% of the titanium alloy content, with balanced strength and plasticity, and can be strengthened by heat treatment.
Usage: aviation structural components, landing gear, blades, artificial joints, ship propellers.
4. β - type titanium alloy (TB2/TB8/TB10, etc.)
Characteristics: Ultra high strength, good cold forming, excellent hardenability, with a strength of up to 1100-1400MPa.
Usage: Aviation fasteners, missile shells, high-performance springs, lightweight structural components.
2、 Main processing techniques
Forging: Hot forging at 900-1100 ℃ to refine grains, eliminate defects, and produce bars/plates/billets.
CNC precision machining: low speed (<60m/min), large feed rate, sufficient cooling, using YG hard alloy cutting tools, anti bonding and hardening.
Welding: argon arc welding/electron beam welding, protective atmosphere against oxidation, joint strength up to 90% of the substrate.
Surface treatment: anodizing (coloring+wear resistance), micro arc oxidation (biological activity), polishing, acid pickling and passivation.
