Performance Comparison and Selection Criteria
When selecting custom automotive parts, several key performance metrics must be considered to ensure optimal results.
Performance Metrics Analysis
Strength-to-Weight Ratio
- Carbon fiber: 2.32 x 10^6 m²/s² (highest performance)
- Titanium alloy: 1.99 x 10^6 m²/s²
- Aluminum alloy: 1.05 x 10^6 m²/s²
- High-strength steel: 0.65 x 10^6 m²/s²
Fatigue Resistance
- Titanium alloy: 10^7 cycles at 50% of tensile strength
- 4340 steel: 10^7 cycles at 45% of tensile strength
- 7075 aluminum: 10^7 cycles at 35% of tensile strength
- Carbon fiber: Dependent on fiber orientation and resin system
Corrosion Resistance
- Titanium alloy: Excellent resistance to saltwater and chemicals
- Stainless steel: Good resistance with proper surface treatment
- Aluminum alloy: Requires anodizing or coating protection
