مواد

Stainless Steel SUS304:

Medical-grade SUS304 stainless steel (austenitic chromium-nickel alloy), offering excellent corrosion resistance and mechanical properties.

التوافق الحيوي: Low risk of allergic reactions or toxicity, ideal for direct tissue contact in medical procedures.
Mechanical Properties: High tensile strength (approximately 505 MPa) and elongation (up to 40%), providing flexibility without brittleness.
Surface Finish: Laser-machined for smooth, burr-free edges, reducing the potential for tissue trauma or contamination.
Thermal Stability: Maintains integrity across a wide temperature range, suitable for sterilization processes like autoclaving.

Nickel-Titanium alloy:

النيتينول (NiTi)، وهو سبيكة من النيكل والتيتانيوم، مشهور بمرونته الفائقة وذاكرته الشكلية، مما يجعله رائدًا في التطبيقات الطبية. بفضل قوة شد تصل إلى 1200 ميجا باسكال ومعامل مرونة يتراوح بين 40 و75 جيجا باسكال، يتفوق النيتينول في البيئات الصعبة.

Cobalt-chrome alloy:

الكوبالت-كروم (CoCr)، وهو سبيكة من الكوبالت والكروم، غالبًا ما تُعزز بالموليبدينوم، يتميز بقوته الاستثنائية ومقاومته للتآكل وتوافقه الحيوي. بفضل قوة شد تتراوح بين 800 و1500 ميجا باسكال وصلابته التي تتراوح بين 300 و550 فولت، يُعدّ CoCr حجر الزاوية في التكنولوجيا الطبية. وتُحسّن درجاته الشائعة مثل L605 (Co-Cr-W-Ni) وMP35N (Co-Cr-Ni-Mo) من أدائه.
