1.Dynamic Speed vs. Static Force:
- Aluminum: Low mass and inertia; optimized for high-speed, moving axes.
- Carbon Steel: High rigidity and shear resistance; ideal for heavy axial loads and impact stops.
2.Environmental Compatibility:
- Black Oxide Steel: Best for dry, indoor industrial use (most economical).
- Nickel-Plated Steel: Resists rust in humid or damp environments.
- Stainless Steel (SUS304/SUS316): Recommended for direct water contact, chemical washdowns, and marine applications.
3.Sanitary & Cleanroom Standards:
- Stainless Steel: Mandatory for food, pharma, and medical lines. Solid construction eliminates the risk of plating flakes contaminating the product.
4.Adjustment Frequency (Galling Prevention):
Avoid dry stainless fasteners on stainless collars for frequent adjustments due to galling risk. Use nickel-plated steel or apply food-grade thread lubricant.
