Alloy 693 is primarily composed of nickel, chromium, and aluminum, designed for high-temperature applications requiring excellent oxidation resistance.
The typical chemical composition of Alloy 693 is:
| Element | Typical Percentage (%) |
|---|---|
| Nickel | 60.5 |
| Chromium | 29 |
| Aluminum | 3.1 |
This specific blend makes Alloy 693 a robust nickel-chromium alloy, well-suited for environments where resistance to oxidation is critical, particularly at elevated temperatures. While these percentages represent the typical composition, it is important to note that specific limiting compositions are also defined for this alloy, ensuring its performance and compliance with industry standards.
