Titanium has been around since 1790 and gets it name from the Greek God “Titan”, the God of enormous strength. Not until 1910, 120 years since the discovery of the ore in England, was there a process developed that allowed the metal to be extracted from the ore.
The individual responsible for this process was a gentleman by the name of M.A. Hunter. The basic process created by Mr. Hunter involved mixing TiO2 with coke and chlorine. When heat was applied to the TiO2 the resulting product was TiCl4. Then sodium was used to reduce the TiCl4 . At this point in time, the titanium produced by this method was used as an alloying agent in the production of steel.
For decades titanium was considered an “aerospace metal” and was used exclusively in this application. As time went on, the corrosion properties of the metal were explored in non-aerospace applications, specifically as a tubing product used in heat exchangers for power generation. This application proved to be extremely successful and the “industrial” market was created.
All of the Spears Titanium products are Grade 5, also known as Ti6Al4V, Ti-6Al-4V or Ti 6-4, is the most commonly used alloy. It has a chemical composition of 6% aluminum, 4% vanadium, 0.25% (maximum) iron, 0.2% (maximum) oxygen, and the remainder titanium.It is significantly stronger than commercially pure titanium while having the same stiffness and thermal properties (excluding thermal conductivity, which is about 60% lower in Grade 5 Ti than in CP Ti). Among its many advantages, it is heat treatable. This grade is an excellent combination of strength, corrosion resistance, weld and fabricability.
