FAQ
Q1: What is the difference between C10100 and C10200?
A: C10200 has an oxygen content ≤0.001%, slightly lower conductivity (100% IACS), and lower cost.
Q2: How to store to prevent oxidation?
A: Vacuum packing or nitrogen-filled storage is recommended, with humidity ≤40%RH.
Q3: Is plating supported?
A: Silver/nickel/tin plating is possible; acid cleaning (e.g., 5% sulfuric acid solution) is required first to remove surface oxides.
