Titanium Bolts vs. Steel

Compared with steel bolts, Titanium can be as strong as mild steel or stainless steel’s, but only 60% weight less than steel’s. The tensile strength of aircraft grade titanium 6AL-4V (grade 5) can reach a minimum of 895mpa, so the strength of Titanium is much higher than that of stainless steel bolts.

Here is the comparison of parameters:

  Titanium Steel
Density   4420kg/m3 (276lb/ft3) 8030kg/m3(501lb/ft3)  
Young’s Modulus   110GPa (16 x 106psi) 193GPa (28 x 106psi)
Yield Strength 828 MPa (120 x 103 psi) 260MPa (37.7 x 103 psi)
Ultimate Tensile Strength  1030MPa (149 x 103 psi) 570MPa (82.7 x 103psi)
Compressive Strength  960MPa (139 x 103 psi) 260MPa (37.7 x 103psi)
Shear Modulus 43GPa (6.24 x 106 psi) 78GPa (11.3 x 106 psi)
Ductility  10% elongation at break 40% elongation at break
Poisson’s Ratio   0.34 0.27
Hardness    36 Rockwell C 95 Rockwell B+
Strength-to-Weight Ratio 187kNm/kg 32.4kNm/kg
Stiffness-to-Weight Ratio 24.9MNm/kg 24 MNm/kg

Characteristics of Titanium

 

titanium 

  • Lightweight: It has the highest strength-to-density ratio of any metallic element.
  • Titanium vs Aluminum vs Steel: It’s as strong as steel but 45% lighter and twice as strong as aluminum but only 60% heavier.
  • Corrosion resistant: It is highly resistant to corrosion even in sea water, aqua regia and chlorine.
  • Bio-compatible: It is non-toxic, non-allergenic and perfectly compatible with the human body.
  • Durable: It is more durable than gold and has become a popular jewelry choice.

Aerospace Area

Titanium is also known for its substantial resistance to high temperatures, and that turns it into the most preferred metal in aerospace applications. With the advent of jet engines, its role has become even more crucial.

Due to its weight and flexibility, Titanium is widely used in the petroleum and engineering industries. This metal is an ideal choice if you are committed to producing pipes, water management systems, or other deep-water units. In addition to withstanding heavy loads, Titanium cannot be affected by saltwater. That is why it is common to make various extraction equipment, propeller shafts, valves, and fittings.

Motorbike

Lighter than steel and stronger than aluminum, Titanium has long been considered one of the best – and luxurious – metals for making a bicycle frame. While carbon fiber is the material of choice for top racing frames, Titanium is no slouch when put to good use.

Implants

Titanium Bolts can also have good compatibility with human tissues and blood, even in the human body, widely used in heart stents, intramedullary nails, implant teeth, therapeutic devices, and some physical therapy equipment with more contact with the human body. The fastener parts in this equipment must also be titanium fasteners.

Anodizing Various Colors

Titanium anodizing is an electrolytic finishing process that manipulates the oxide layer on the surface of Titanium via electric current. The titanium item forms the anode (positive electrode) of an electrolytic cell, hence “anodize.”
