　　What is Titanium Alloy Stamping?

　　Titanium Alloy Stamping is a high-end precision forming process specifically designed for titanium and titanium alloy sheets. It processes titanium alloy sheets into various structural and functional parts through customized wear-resistant molds and adaptive process parameters (combined with warm stamping technology in some scenarios). Titanium alloy itself possesses characteristics such as high strength (tensile strength ≥400MPa), lightweight (density only 4.51g/cm³), excellent corrosion resistance, biocompatibility, and high temperature resistance (up to 500℃). The stamping process achieves precise forming of parts and integrated manufacturing of complex structures. Its core feature is the dual superposition of "high material performance + high forming precision", making it suitable for high-end scenarios with strict requirements on performance, weight, and reliability.

　　Compared with ordinary metal (steel, aluminum alloy) stamping, its core difference lies in addressing titanium alloy's characteristics of "high strength, poor room-temperature ductility, and significant work hardening". Special process designs such as warm stamping (150-350℃), mold reinforcement, and stepwise forming are required to avoid forming cracks while maximizing the retention of titanium alloy's inherent advantages. It is a key forming solution for high-performance components in high-end manufacturing.

　　How It Works

　　The core of titanium alloy stamping is "precision forming adapted to material characteristics". It overcomes the difficulties of titanium alloy processing through process optimization, achieving a balance between forming quality and material performance. The key processes and control points are as follows:

　　Titanium Alloy Sheet Preparation: Select commercially pure titanium (TA1/TA2) or titanium alloy (TC4/TC11) sheets with a thickness of 0.2mm-8mm; pre-treatment includes oil-free surface cleaning (removal of oxide film) and low-temperature annealing (250-300℃ to improve material ductility). The sheet grain size is selected according to part requirements (≤30μm to ensure forming uniformity).

　　Mold Adaptation and Reinforcement: Molds are made of polycrystalline diamond (PCD) or cemented carbide (WC-Co), with TiN coating treatment on the surface (hardness ≥HRC 70). The mold clearance is set to 1.05-1.1 times the material thickness (adapting to titanium alloy's work hardening characteristics); the blank holder adopts an elastic buffer structure to apply uniform pressure (1-3MPa), preventing cracking caused by local stress concentration.

　　Precision Stamping Forming: Select the forming method according to part complexity—cold stamping (room temperature) for simple parts, and warm stamping (150-350℃ to reduce forming resistance) for complex parts/thick sheets; use a servo hydraulic punch press (pressure control accuracy ±1%) and control the stamping speed (5-50 times/minute, lower than ordinary steel stamping). Complex structures adopt 3-5 stepwise forming passes, with stress relief treatment (180-220℃) after each pass.

　　Post-processing and Inspection: After forming, eliminate internal stress through vacuum annealing (300-400℃), and perform sandblasting or pickling to remove surface oxide scale if necessary; inspection items include dimensional tolerance (±0.01mm-±0.05mm), mechanical properties (tensile strength, elongation), corrosion resistance (salt spray test ≥1000 hours without corrosion), and surface quality (Ra≤0.2μm, no cracks/scratches).

　　Throughout the process, "adapting to titanium alloy characteristics" is the core. By means of temperature control, stepwise forming, and mold reinforcement, the pain points of titanium alloy stamping (ease of
