The main product of GR5 (Ti-6AL-4V) titanium material

Generally, people think that titanium alloy is a very single product. In fact, this perception is inaccurate. There are many classifications of titanium alloys. Titanium is divided into commercial pure titanium and titanium alloys. Products include titanium rods, titanium plates, titanium pipe fittings, wires, forgings, standard parts, fasteners and titanium daily necessities. A variety of titanium alloy products have entered our lives, the most commonly used titanium alloy GR5 , it is also the main force among titanium alloy materials. Let's take a look at titanium alloy GR5.

Among titanium alloys, Gr5 is the main one. At present, 60% of titanium is mainly Gr5. The main composition of Gr5 is Ti-6Al-4V, which is an (α+β) type titanium alloy and has good comprehensive mechanical and mechanical properties.

Gr5 titanium alloy belongs to the national standard name, and different countries have different names.

Gr5 titanium alloy is an α-β titanium alloy successfully developed by the United States in 1954. It contains 6% α-stabilizing element lv (aluminum) and 4% β-stabilizing element V (vanadium). The nominal composition of Gr5 titanium alloy is 6.0 aluminum equivalent, 4.0 vanadium equivalent, and contains 10%-15% β phase in the annealed state.

The thermal conductivity of Gr5 titanium alloy is 1/5 of iron and 1/10 of aluminum. The thermal conductivity of Gr5 is l=7.955W/m·K.

The strength sb of Gr5 titanium alloy reaches 1.012GPa, and its density g is 4.51g/cm3, making the ratio of strength to density sb/g reach 23.5. This value is much higher than the strength-to-density ratio of alloy steel, showing its excellent strength and lightweight properties.

Chemical composition and physical properties of Gr5 titanium alloy:

physical properties

The world's production of Gr5 (Ti-6Al-4V) alloy semi-finished products accounts for more than half of the total output of various titanium alloy semi-finished products, accounting for more than 80% of the total in the aerospace industry. The main semi-finished products of Gr5 titanium alloy are bars, forgings, sheets, Thick plates, profiles and wires, etc.

The main features of Gr5 titanium alloy are excellent comprehensive properties and good process performance. Gr5 titanium alloy has medium room temperature strength and high temperature strength, good creep resistance and thermal stability, high fatigue resistance and crack propagation resistance in seawater, as well as satisfactory fracture toughness and resistance to thermal salt stress corrosion. It is also less sensitive to hydrogen than TC2 and TC1 alloys, and is suitable for manufacturing various parts working in a wide temperature range of -196~450°C, especially parts designed using the damage tolerance limitation principle. Gr5 titanium alloy also has excellent process plasticity and superplasticity, and is suitable for forming using various pressure processing methods, and for welding and mechanical processing in various ways.
