Titanium rod

Product Overview

Ti 6242 titanium alloy rods are near-alpha titanium alloys, also known as Ti-6Al-2Sn-4Zr-2Mo. This high-performance near-alpha titanium alloy uses titanium as the base metal and incorporates carefully proportioned alloying elements such as aluminum, tin, zirconium, and molybdenum, which synergistically enhance its overall performance. Ti 6242 rods have a density of approximately 4.54 g/cm³ (40% lighter than steel) and maintain excellent toughness and structural stability even at operating temperatures up to 550°C, while remaining non-magnetic and non-toxic. It is widely recognized for its ability to withstand long-term use under high temperature, high pressure, and corrosive conditions, outperforming many other titanium alloys under harsh conditions.

Chemical Composition (Weight %)

The precise chemical composition of Ti 6242 titanium alloy bar is strictly controlled to ensure consistent performance, adhering to international standards such as AMS 4975 and UNS R54620. The typical composition is as follows:

Note: Silicon is often added in small amounts to further improve the creep resistance of Ti 6242 (designated as Ti 6242S) for more demanding high-temperature applications.
