The customer chose the appropriate titanium material

Apr. 22, 2019

Engineer Daniel we are very grateful to him, we have cooperated for 6 years!They are an American technology company. Their ocean exploration equipment is made of ti-6al-4v titanium alloy tubes and plates supplied by us.We cooperate very happily!Our high-quality titanium products and sincere and efficient service for the customer's product design to provide a guarantee, of course, we are the right choice!

Titanium alloys are widely used in Marine research, Marine exploration, Marine exploration and Marine engineering and are currently one of the most preferred metallic materials.And if we look at some of the data why?

Ti-6Al-4V titanium alloy (also known as Titanium 6-4 and Grade 5 titanium) is the most commonly used alpha-beta alloy due to an outstanding strength to weight ratio, ability to withstand extreme temperatures, excellent corrosion resistance, and impressive welding and fabrication ability. This makes Ti 6-4 extremely versatile in a number of markets and application including the industrial, aerospace, military, and automotive spaces.
