Titanium Bolts
Titanium Bolts have a very good weight/strength ratio. In many areas of application they are a lightweight alternative to classic steel bolts.
Titanium Bolts, especially in the two most common variants: Titanium Grade 2 (pure) and Titanium Grade 5 (alloyed), offer the best ratio of high tensile strength and low weight (almost half compared to steel bolts) for many applications.
At the same time, they are per se corrosion-resistant and resistant to chemical influences (acids, alkalis,…) as well as against extreme environmental conditions (e.g. sea and salt water), even without additional surface treatment.
Bolts made of Titanium are bio-compatible and tasteless as well as non-magnetic, electrically conductive and heat-resistant.
In addition, it is possible to color them without the insertion or application of foreign substances.

Material Titanium Bolts
(Ti2 / Grade 2 / M.-No. 3.7035)
Pure Titanium Grade 2 is one of the most common materials for the production of Titanium Screws.
Grade 2 Titanium Bolts have a tensile strength of approx. 390-540 N/mm2 and a yield strength of min. 250 N/mm2. Due to the low density (approx. 4.5 g/cm2) and the related low weight, Titanium Bolts are approx. 40% lighter than steel bolts. A lower weight can only be achieved by using Aluminium Bolts.
In addition to good corrosion resistance, Grade 2 Titanium Bolts have the best combination of strength, weldability and formability. Furthermore, they stand out due to their bio-compatibility.

Material Titanium Bolts
(Ti 6Al 4V / Grade 5 / M.-No. 3.7165)
Ti-6Al-4V (Grade 5) is one of the most common alpha + beta alloys for the production of Titanium Fastners.
Grade 5 Titanium Bolts have a high tensile strength (approx. 930-1000 N/mm2) and a yield strength of min. 830 N/mm2. Because of the low density (4.4 g/cm2) and the associated low weight they are approx. 40% lighter than steel bolts.
Titanium Grade 5 alloy has the best combination of strength, toughness and ductility and is the first choice where the ratio of weight to strength or corrosion is essential.
