Medical and Biotechnology Industry 

• The medical industry develops devices and implants for healthcare, requiring biocompatible, corrosion-resistant, sterilizable and degradablematerials.
• Properties include leachability (minimal ion release per ISO 10993-5), corrosion resistance (stable at 121°C), shrinkage rate (e.g., Zamak 3: 0.6%), and surface roughness (Ra, e.g., 0.5 µm post-plating). Applications: surgical instruments, orthopedic implants, dental tools. Recommended alloys: Zamak 3, custom zinc alloy.
• Zinc alloys are selected for biocompatibility, ease of sterilization, precision casting, and resistance to bodily fluids.
• zinc alloys are used for surgical instruments, orthopedic implants, and dental restoration materials, biodegradable implants,typically produced through die-casting or gravity-casting techniques.
