Titanium Bolts VS Steel Bolts

Titanium Bolts VS Steel Bolts

Titanium Bolts has many advantages which steel bolts can’t match.Below are the advantages of titanium bolts compared with steel bolts.

1. Low Density and High Strength

The density of titanium is 4.51g/cm³, which is higher than aluminum but much lower than steel, copper and nickel. Compared with steel bolts, titanium bolts can save 40% weight.

The tensile strength of the most common titanium alloy grade 5 can reach a minimum of 895mpa, so the strength of titanium bolts is much higher than that of stainless steel bolts. For ordinary pure titanium, such as grade 2, the tensile strength is lower than that of stainless steel bolts.

2. Excellent Corrosion Resistance

Titanium is very stable in many media, such as titanium in oxidizing, neutral and weak reducing media is highly resistant to corrosion. So titanium bolts are widely used in chemical industry.

3. Heat Resistance and Low Temperature Resistance

The titanium bolts can be used for a long time at 600 ℃ or higher. Titanium alloy TA7 (ti-5al-2.5sn), Grade 5 (Ti-6Al-4V) and Ti-2.5Zr-1.5Mo are representative of low-temperature titanium alloy. They maintain good ductility and toughness at low temperature of – 196-253 ℃ and avoid cold brittleness of metal. They are ideal materials for low-temperature vessels, tanks and other equipment.

4. Non Magnetic and Non-Toxic

Titanium is a non-magnetic metal and will not be magnetized in a large magnetic field. Titanium bolts have been widely used in the fields of medical treatment and electronic industry.

5. Biocompatibility

Titanium Bolts can also have good compatibility with human tissues and blood even in the human body. At present, titanium is mainly 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 these equipment must also be titanium fasteners.

6. Can be anodized to many colors

Compared with Steel bolts,titanium bolts can be anodized to many colors including Gold,Blue,Black,Purple,Green and Rainnow colors.
