Material Composition | Heavy-duty trucks, SUVs | Steel (ASTM A36) ▲ High-Strength Steel (ASTM A533, 20% stronger) ▲▲ Aluminum Alloy (6061-T6, 30% lighter than steel) | Enhanced durability and corrosion resistance (Base); Lightweight agility (Advanced) | Higher cost for advanced materials (▲▲ tier) |
Structural Rigidity | Racing vehicles | 500 MPa (Industry) ▲ 600 MPa (▲ 20% stronger, ASTM E8/E8M) ▲▲ 700 MPa (▲▲ 40% stronger, custom alloy) | Superior handling under high stress; reduces deformation during cornering | Increased material cost and complexity in manufacturing |
Corrosion Resistance | Coastal regions, salt-exposed environments | 200h salt spray (ASTM B117) ▲ 300h (▲ 50% longer resistance) ▲▲ 500h (▲▲ 150% better than Industry) | Extended lifespan in harsh environments; reduces rust-related repairs | Advanced coatings add to production costs |
Compatibility | Specific vehicle models (Alfa Romeo 147/156 GT) | Generic fit ▲ OEM-specific (▲ Perfect fit for target models) ▲▲ Custom-fit (▲▲ Tailored to engine specs) | Eliminates misalignment issues; reduces installation time for OEM models | Limited to specific vehicle lines; custom-fit requires engineering adjustments |
Installation Complexity | DIY enthusiasts, professional mechanics | 4h (Industry) ▲ 3h (▲ 25% faster) ▲▲ 2h (▲▲ 50% faster with torque wrench) | Faster assembly with minimal tools (Base); Advanced kit includes pre-assembled joints | Advanced versions require specialized tools (e.g., torque wrench) |
Weight | Performance vehicles, fuel-efficient cars | 5kg (Steel) ▲ 4.5kg (▲ 10% lighter) ▲▲ 4kg (▲▲ 20% lighter, improves fuel efficiency) | Reduces unsprung weight for better handling; lowers fuel consumption | Aluminum alloy and composite components cost 30–50% more than steel |
