Key Difference:
-
Nb521 contains W but no Ti, while C103 contains Ti but no W - this is their fundamental distinction.
-
C103's higher Ti/Zr ratio enhances oxidation resistance, whereas Nb521's tungsten provides high-temperature strength.
2. What is the composition of Nb521 Alloy Powder?
The "521" moniker denotes 5% tungsten (W), 2% molybdenum (Mo), and 1% zirconium (Zr), with 95% niobium (Nb).
3. What Are the Advantages of Nb521 Alloy Materials?
Nb521 Nb-W alloy material is excellent in mechanical properties at room temperature and at high temperature, high melting point, low density, high-temperature strength, and machinability.
