Material Composition | Aerospace, marine environments | Industry: ASTM A307 steel (70 ksi yield) Base: ▲ ASTM F139 Ti (105 ksi yield, 45% lighter than steel) Advanced: ▲▲ ASTM F147 Ti (120 ksi yield, 20% stronger than Base) | Base reduces weight by 45% while maintaining strength; Advanced enhances strength-to-weight ratio | Higher cost; may require non-magnetic tools |
Surface Treatment | Architectural, chemical exposure | Industry: Zinc-plated (ASTM B695, 500h salt spray) Base: ▲ Gold finish (ASTM B201, 1000h salt spray) Advanced: ▲▲ Anodized gold (ASTM B204, 2000h salt spray) | Base offers double corrosion resistance; Advanced provides twice the durability | Gold finish may not withstand high friction; Advanced coating needs inspection |
Thread Specifications | Precision machinery | Industry: M7 ISO 261 class 6g (±0.02mm tolerance) Base: ▲ class 5g (±0.015mm) Advanced: ▲▲ class 4g (±0.01mm) | Base improves precision by 17%; Advanced offers 30% tighter fit | Tighter tolerances require precise machining tools |
Flange Design | Heavy-duty torque applications | Industry: Hex flange (6 sides, 60° increments) Base: ▲ 12-point (30° increments) Advanced: ▲▲ 12-point + locking feature | Base doubles tool engagement points; Advanced prevents loosening under vibration | Requires specialized wrenches; locking feature adds cost |
Weight/Strength Ratio | Lightweight equipment | Industry: Steel (density 7.85 g/cm³, 70 ksi) Base: ▲ Ti (4.5 g/cm³, 105 ksi) Advanced: ▲▲ Ti alloy (4.4 g/cm³, 120 ksi) | Base reduces weight by 45% without strength loss; Advanced boosts strength by 14% | Higher cost; potential galvanic corrosion with dissimilar metals |
Corrosion Resistance | Marine, coastal areas | Industry: Stainless steel (ASTM A193 B8, 1000h salt spray) Base: ▲ Ti (ASTM B117, 2000h) Advanced: ▲▲ Ti+PTFE (3000h) | Base doubles salt spray resistance; Advanced adds chemical resistance | Coatings require periodic inspection; Advanced version may be more expensive |
