SoluMag Controlled High Corrosion Magnesium Alloy,E FOUR

### **SoluMag™ Controlled High Corrosion Magnesium Alloy** **Product Overview** SoluMag™ represents a breakthrough in magnesium alloy technology, specifically engineered to deliver controlled, predictable corrosion rates for biomedical and industrial applications. Unlike conventional magnesium alloys where corrosion resistance is maximized, SoluMag™ is designed to biodegrade at a predetermined rate when implanted in the human body or exposed to specific environments. This unique characteristic makes it ideal for temporary medical implants that naturally dissolve after fulfilling their function, eliminating the need for secondary removal surgery. The alloy achieves this controlled corrosion through precise chemistry and advanced microstructure engineering, offering a safe and biocompatible solution for next-generation medical devices. --- #### **1. Chemical Composition** SoluMag™ features a carefully designed composition free from toxic elements, ensuring biocompatibility while maintaining controlled degradation. | Element | Composition (% by Weight) | | :---------------- | :-------------------------------- | | **Magnesium (Mg)** | ≥ 99.8 % | | **Specified Additives*** | 0.05 - 0.20 % | | **Iron (Fe)** | ≤ 0.005 % | | **Nickel (Ni)** | ≤ 0.001 % | | **Copper (Cu)** | ≤ 0.005 % | | **Cobalt (Co)** | ≤ 0.001 % | | **Other Impurities** | ≤ 0.05 % (each) | *Note:* The specific additive elements are proprietary but consist of biocompatible elements that modify the corrosion behavior without causing adverse biological reactions. The extremely low levels of iron, nickel, and copper are critical for controlling corrosion rates and ensuring biocompatibility. --- #### **2.
