Products Description
Brilliant for saltwater environments
Machinable at slow speed with the right amount of coolant flow and high feed rates
Great fracture toughness and fatigue strength
Highly durable and resistant to corrosives
Titanium alloy grade 23 is a strong and durable alloy with excellent resistance against acidic or gaseous corrosions.
It is tough in air and saltwater environments and thus is deployed in the manufacturing of aerospace and marine vessels.
It is the most commonly used alloy of the alpha-plus-beta class.
The interstitial elements like Iron and Oxygen are low in concentration as compared to many other Titanium alloys such as TA1 (GR.1) , TA2 (GR.2), TA3 (GR.3), TA4 (GR.4). It confers to improved ductility of the material. Hence, it is also known as Ti-6Al-4V-ELI, where ELI stands for Extra Low Interstitial.
Being castable, it is also used in sporting goods.

Key Features:
Incredible ductility: The Ti 6Al-4V ELI is a highly malleable material. It can be shaped easily into parts that are desirable for machinery. The ELI property confers this quality to the alloy, and hence it is readily accepted in multiple industrial manufacturing units.
Superior damage and corrosion resistance: Titanium grade 23 can efficiently resist gaseous and acidic corrosion of any form. Thus, it can stay free from damage for a longer period, thus increasing the lifetime of the machinery formed out of it.
Lightweight but durable: Though this alloy is lighter than many, yet it has impressed the industries with its incredible strength. Thus, it is effectively used in the construction of aerospace and marine industries.
