What is grade 5 titanium?
Jan 15, 2026
What is GR5 titanium?
Grade 5 titanium is an alpha-beta alloy, made up of 6% aluminium and 4% vanadium. It accounts for around 50% of global titanium alloy usage and is readily available. Nicknamed the 'workhorse alloy', grade 5 is appropriate for highly demanding applications; benefiting from exceptional strength and high heat and corrosion resistance. As well as being widely used in aerospace applications, it's also popular in the medical industry and in particular surgical implants.

Titanium grade 5 machinability
The machining characteristics of titanium are similar to those of austenitic stainless steel. Lower cutting speeds are recommended to minimize heat buildup. Higher cutting speeds will significantly shorten tool life. GNEE's engineering team has extensive experience in machining titanium and understands how to select appropriate tools and machining parameters to fully utilize the properties of titanium.
