Available titanium alloys for nuts

When choosing titanium nuts, each of the four common titanium grades offers its own strengths and focus.

Why choose titanium nuts?

• Reduce weight by up to 40% without sacrificing strength—ideal for unsprung mass or overall body weight savings.
• Grade 5 offers tensile strength comparable to 10.9-grade alloy steel; Grade 2 is twice as strong as A4 stainless steel.
• Zero pitting after 20 years in 3.5% salt spray—resistant to acids, alkalis, H₂S, and chlorides.
• Grade 5 handles continuous temps up to 400 °C and short bursts up to 550 °C
• Non-magnetic and sensor-safe—won't interfere with MRI, avionics, or precision instruments.
• Supports anodizing in 8 vivid colors (blue, purple, gold, etc.) and MoS₂ anti-galling coating for both looks and function.

Industry applications

Lightweight vehicle upgrades

Each titanium nut cuts unsprung weight by 40%, boosting acceleration and adding a colorful edge.

Anodized flange nuts with serrations reduce wheel mass and fight vibration. Thin hex nuts lower stack height at frame joints.

12-point lug nuts allow easy torqueing in recessed wheel hubs.

One Porsche 911 (M14×1.5) saw a 1.25 kg reduction in unsprung weight—0–100 km/h acceleration improved by 0.05 seconds.

Aerospace

MS 21244 12-point nuts and metal locknuts pass NASM 1312-13 vibration and thermal testing.

They hold preload from −50 °C to 200 °C—every gram saved means more altitude for spacecraft.

Compact engines and satellite bays benefit from 30° incremental torqueing with short-handle wrenches.

Marine and shipbuilding

Heavy-duty hex nuts deliver ≥ 250 Nm preload in high-torque flanges.

Weld nuts with ring projections focus heat and avoid thread annealing post-weld.

DNV-certified saltwater tests show Grade 5 titanium resists pitting for 20+ years in 3.5% NaCl—cutting dry dock costs.

Petrochemical and energy

Grade 5 heavy nuts paired with nylon or metal locknuts maintain sealing under 200 bar and H₂S-rich acidic conditions.

All locknuts pass ISO 2320 reuse testing—retaining ≥ 80% of their original torque after 30 disassemblies for easy maintenance.

Frequently asked questions (FAQ)

What are the benefits of titanium nuts?

They're 40% lighter than steel nuts of the same size, with tensile strength up to ≥ 950 MPa.

They offer 20-year corrosion resistance in seawater, are non-magnetic, and support colorful anodized finishes.

How strong are titanium nuts?

Grade 2 (commercial pure titanium) offers ≥ 345 MPa tensile strength—about 2× stronger than A4 stainless steel.

Grade 5 (Ti-6Al-4V) reaches ≥ 950 MPa, rivaling 10.9-grade steel while being 40% lighter.

Are titanium bolts safe?

Yes. Titanium bolts use Grade 2 or Grade 5 alloys, with excellent tensile and fatigue strength.

They resist corrosion and chloride pitting, are non-magnetic and biocompatible—trusted in aerospace, medical, and marine applications where safety and reliability are critical.
