Fasteners and fixings must be effective, and their appearance is not always important, especially when used in industrial applications or where they are hidden from view. Titanium is a gleaming silver metal that will stand out from afar and maintain a quality aesthetic appearance for a longer period of time. Furthermore, its low density, high-temperature resistance, and excellent corrosion resistance make it a popular choice for a variety of applications.
Applications for Titanium Fasteners
Titanium has a high strength-to-weight ratio, is strong and relatively ductile, and has a high melting point, making it useful in high-temperature applications.
Titanium's strength and light weight make it extremely unique, and some grades of Titanium can be two to four times stronger than Stainless Steel. Titanium is ideal for some aerospace, medical, and military applications due to its properties.
Titanium Nuts are saltwater resistant, making them ideal for use in maritime applications. They are also resistant to nearly all chlorine and chloride solutions, including chlorite, hypochlorite, chlorate, perchlorate, and chlorine dioxide. However, if chlorine is used in the absence of water or as a gas, it can cause rapid corrosion.
Titanium screws and fixings are used in applications that require a high strength-to-weight ratio, excellent stress corrosion cracking resistance, and high corrosion resistance.
One thing to keep in mind is that, while titanium has excellent chlorine resistance, it reacts poorly to strong acids such as hydrochloric acid or sulfuric acid, which attack the protective passive layer that Titanium forms when exposed to oxygen. This can result in corrosion.
Titanium Types Used in Fasteners and Fixings
We typically stock fasteners made of Titanium Grade 2 or Titanium Grade 5.
Titanium Grade 2 is a “commercially pure” unalloyed titanium. Because of its moderate strength, excellent aqueous corrosion resistance, and formability, this is widely used in industrial applications.
Titanium Grade 5 contains 6% aluminum and 4% vanadium. Titanium fasteners of Grade 5 can withstand temperatures of over 400 degrees Celsius and are extremely strong, making them popular in maritime and aerospace applications.
