If you supply, fabricate, or specify metal for industrial projects, the question of Titanium Grade 5 vs. Grade 2 Plates<\/strong> eventually lands on your desk. Both are made of titanium, and both are more corrosion-resistant than steel, but they are not equivalent. Titanium Grade 2 Plates<\/b> are commercially pure titanium, designed for formability and corrosion resistance in medium-strength applications, and Titanium Grade 5 Plates<\/b> are an aluminium-vanadium alloy for high strength and high-temperature use. If material for chemical equipment, marine hardware, or aerospace brackets is needed by a small or mid-sized business, selecting the wrong grade can result in paying more than necessary for the required strength or in a part that is weaker than required, which may then fail under load. This guide explains the composition, properties, and uses of each grade to help you make a decision with confidence.<\/p>\n Key Takeaways<\/p>\n Titanium Grade 2<\/b> is the workhorse of the commercially pure (CP) titanium family, essentially unalloyed titanium, with only trace amounts of iron and oxygen controlling its strength. This promotes softness and flexibility when bending or rolling, making it a popular choice for fabricators creating tanks, ducting, and heat exchanger parts for tight forming tolerances.<\/p>\n It can also withstand seawater, chlorides, and most industrial acids without pitting, which can ultimately damage stainless steel. The typical values for Titanium Grade 2 plate<\/a> are a minimum tensile strength of 345 MPa, a minimum yield strength of 275 MPa, and an elongation of approximately 20%, as stated in the ASTM B265 specification for titanium strip, sheet, and plate. The combination of moderate strength and formability makes it the choice of material whenever weldability and corrosion resistance trump raw mechanical strength.<\/p>\n Titanium Grade 5<\/b>, also known as Ti-6Al-4V, is an alpha-beta alloy composed of approximately 90% titanium, 6% aluminium and 4% vanadium. Aluminum provides increased strength and heat resistance, and vanadium improves toughness and fatigue resistance, making the plate a lighter alternative to high-strength steel rather than “soft” titanium.<\/p>\n With a minimum tensile strength of 895 MPa and a yield strength of 828 MPa, Titanium Grade 5<\/a> generally offers higher strength than Grade 2 and is around 60% lighter than comparable steels. The ratio is why aerospace, defense, and motorsports use Ti-6Al-4V, as discussed in our article on Ti-6Al-4V round bars for automotive performance parts<\/a>. The trade-off is lower ductility (elongation drops to around 10%) and harder machining and welding.<\/p>\n\n
