Dear Customer:

The current international situation is complex and volatile, and uncertain tariff policies may potentially impact our product prices. Given these uncertainties, we value your understanding regarding order-related matters.

If you decide to place an order during this period, we reserve the right to adjust the price based on the evolving situation. We understand that market changes may cause inconvenience. We will negotiate with you if there’s a significant price fluctuation due to tariff policy changes before the order’s actual delivery, and in such cases we may adjust or cancel the order as necessary.

    Biomedical Implant Devices Fabricated from Low Young’s Modulus Titanium Alloys Demonstrating High Mechanical Biocompatibility

    Biomedical implants are essentially foreign substances within the human body that must survive many years’ exposure to demanding mechanical and physiological conditions. Despite these challenges, metal implants have been widely used to substitute for or rebuild hard tissues such as bones and teeth.
