Titanium has the highest strength to weight ratio. A 6al 4v titanium application is just one of the many applications that can be made when using titanium to aid joint replacements or high powered devices’ structural components. Titanium alloys are classified into three key categories, namely alpha, beta and alpha-beta.
Alpha alloys will not be heat treatable. They only have neutral alloying elements, tin would be a good example, or alpha stabilizers, like aluminum and oxygen. Beta alloys are what they call metastable. This means that the contain enough beta stabilizers, like molybdenum and vanadium, and this allows them to completely retain a beta phase during quenching. They will be solution treated and aged in order to achieve required increases in strength.
To various degrees, alpha beta alloys will be heat treatable. They will contain a combination of alpha and beta stabilizers. The 6al 4v titanium remains the most common alloy. It accounts for over fifty percent of total titanium use. It is an alpha beta alloy that is heat treatable and can achieve moderate increases in strength.
The abovementioned titanium is ideal as a lightweight alloy with good corrosion resistance. It is operable at high strength and at low to moderate temperatures. It is ideal for use in medical devices, high performance automotive parts, marine and sports equipment, as well as aircraft structural components and aircraft turbine engine components.
The titanium 6al 4v eli is higher in purity than the previously mentioned titanium. This alpha beta alloy does have lower specified limits on iron and interstitial elements of carbon and oxygen. Owing to its good biocompatibility, this model is perfectly equipped for numerous medical and dental applications.
It has good fatigue strength and a low modulus. It is of high strength, light in weight and has good corrosion resistance.
