### **Technical Datasheet: Nickel 200 Foil & Shim Stock (UNS N02200)** #### **1. Product Overview** **Nickel 200 Foil and Shim Stock** represent the thin-gauge forms of commercially pure nickel (99.6% minimum), engineered for applications requiring precise thickness control, excellent formability, and the characteristic corrosion resistance of Nickel 200. **Foil** is typically supplied in thicknesses from 0.001" to 0.005" (0.025 mm to 0.127 mm), while **Shim Stock** generally ranges from 0.006" to 0.030" (0.15 mm to 0.76 mm). These products maintain the same excellent corrosion resistance and mechanical properties as other Nickel 200 forms, but are optimized for applications where minimal thickness and maximum flexibility are critical. #### **2.
