## Common ground
All options refer to cam levers—mechanical components used to control or transmit motion, typically in industrial or mechanical systems.
## Options at a glance
**7326.90 – Stainless steel**
- **Defining trait:** Made from corrosion-resistant stainless steel, ideal for harsh or wet environments.
- **Typical examples:** Cam levers in food processing equipment, marine applications, chemical plants.
- **Best fit when:** Exposure to moisture, chemicals, or high hygiene standards is required.
**7616.99 – Aluminium**
- **Defining trait:** Made from lightweight aluminium, offering strength with reduced weight.
- **Typical examples:** Cam levers in aerospace components, robotics, consumer electronics.
- **Best fit when:** Weight reduction is critical, and corrosion resistance is less of a concern.
## Key differences
| Feature | 7326.90 (Stainless steel) | 7616.99 (Aluminium) |
|--------------------|----------------------------|----------------------|
| Material | Stainless steel | Aluminium |
| Weight | Heavier | Lighter |
| Corrosion resistance | High | Moderate |
| Typical use | Harsh environments | Lightweight systems |
## How to choose
- Is the lever exposed to moisture, chemicals, or high hygiene needs? → 7326.90
- Is weight a key concern (e.g., in moving parts or portable devices)? → 7616.99
## Overlaps & pitfalls
A cam lever could technically fit both if it’s used in a moderately corrosive environment and requires light weight—but the material choice defines its primary function. If unsure, prioritize the **main environmental exposure** (e.g., wet vs. dry) or **weight constraint**. No option is vague; both are clearly defined by material
