Unparalleled Material Advantages
Our titanium dome nuts are manufactured using premium-grade titanium alloys, primarily:
Grade 2 Titanium (Commercially Pure):
Exceptional corrosion resistance
Excellent formability and weldability
Ideal for marine and chemical processing applications
Tensile strength: 345 MPa (50 ksi) minimum
Grade 5 Titanium (Ti-6Al-4V):
The most widely used titanium alloy
Outstanding strength-to-weight ratio
Maintains integrity in extreme temperatures (-250°C to 500°C)
Tensile strength: 950 MPa (138 ksi) minimum
Compared to traditional steel fasteners, our titanium dome nuts offer:
40-50% weight reduction
Superior corrosion resistance (no galvanic issues)
Non-magnetic properties (crucial for medical and electronics)
Excellent fatigue resistance
Engineering Excellence in Design
The dome nut's distinctive acorn shape provides multiple functional benefits:
Thread Protection:
The enclosed dome design safeguards internal threads from damage, contamination, and environmental exposure, significantly extending service life in harsh conditions.
Aerodynamic Profile:
The smooth, rounded surface reduces air resistance in high-velocity applications (racing, aerospace).
Safety Enhancement:
Eliminates sharp edges, making these nuts ideal for consumer products and medical devices.
Customization Options:
Flange Variations: Smooth or serrated (for vibration resistance)
Thread Types: Metric (M1-M30), UNC, UNF, or custom threading
Surface Finishes: Natural titanium, polished, anodized (multiple colors), or PVD coated
