One of the main advantages of titanium fasteners like bolts, screws, nuts, and washers is their strong yet lightweight nature. Titanium has a low density but high tensile strength, making it nearly 50% lighter than steel while maintaining similar strength levels. Compared to aluminium, titanium is over 50% stronger despite having a higher density, creating an unmatched strength-to-weight ratio.

Titanium fasteners also resist corrosion from chloride, chlorine solutions, and both natural and sea water due to a protective passivation layer that forms in oxygen-rich environments. This layer enhances resistance to various types of corrosion over time. Additionally, titanium has a high melting point of around 1650°C, and it is usually non-toxic and non-magnetic, which is useful in applications where magnets are a consideration.

However, titanium may not be suitable for every use. Its corrosion resistance is lower against hydrochloric and sulfuric acids, as well as dry chlorine or chloride gases. It also has low thermal and electrical conductivity, making it less ideal for electrical applications. Titanium can lose strength at temperatures above 400°C, and its cost can be a drawback, being more expensive than other materials like stainless steel and aluminium.

Choosing the right grade of titanium includes options such as Grade 2, which is commercially pure and twice as strong as A4 stainless steel, and Grade 5, known as the “workhorse” grade, which is four times stronger than A4 stainless steel. Grade 7, which includes palladium for added corrosion resistance, is used in highly chemical-sensitive applications, while Grade 23 offers increased ductility and is biocompatible for medical uses.
