GR5 Titanium alloy rod Introduction:
Titanium alloy GR5 material composition is Ti-6Al-4V, belongs to (α+β) type titanium alloy, has good comprehensive mechanical mechanical properties. The specific strength is greater. The strength of GR5 sb=1.012GPa, density g=4.4*103, specific strength sb/g=23.5, while the specific strength of alloy steel sb/g is less than 18. Titanium alloys have low thermal conductivity. The thermal conductivity of titanium alloy is 1/5 of iron, 1/10 of aluminum, and the thermal conductivity of GR5 l=7.955W/m·K. Linear expansion coefficient =7.89*10-6℃, specific heat =0.612cal/g·℃. The elastic modulus of titanium alloy is low. The elastic modulus of TC4 is E=110GPa, which is about 1/2 of steel, so titanium alloy is easy to deform during processing.
GR5 Titanium alloy rod application:
GR5 titanium alloy has excellent corrosion resistance, small density, high specific strength and better toughness and weldability and a series of advantages, in aerospace, petrochemical, shipbuilding, automotive, medicine and other sectors have been successfully applied.
What is the difference between pure titanium rod and GR5 titanium alloy rod?
Pure titanium is a type of industrial titanium with a single alpha phase. The industrial pure titanium commonly used in industry is GR2, because of its corrosion resistance and comprehensive mechanical properties are moderate. GR3 can be used when the wear and strength requirements are high. GR1 can be used for better molding performance.
Pure titanium is 99% titanium, 90% titanium alloy, "low thermal conductivity", that is, slow heat transfer. If the heat transfer is slow, the heat will accumulate locally when processing, and it is easy to burn the tool, so in order to not produce a lot of heat, the cutting speed of the tool when processing titanium alloy is very slow, so the processing time is very long.
Industrial pure titanium is divided into gr1, gr2 and gr3 grades according to its impurity content. The gap impurity elements of these three kinds of industrial pure titanium are gradually increased, so their mechanical strength and hardness are also gradually increased, but the plasticity and toughness are correspondingly decreased.
When the iron content of gr1 and gr2 is 0.095%, oxygen content is 0.08%, hydrogen content is 0.0009%, nitrogen content is 0.0062%, it has good low temperature toughness and high low temperature strength, and can be used as low temperature structural materials below -253℃.
Titanium alloy
GR5 titanium alloy rod is widely used in industrial scientific research and other fields, the rapid development of titanium alloy has been recognized by the international industrial aerospace and other fields, especially GR5 titanium alloy rod TC4 titanium forging market prospects are good, Ti-6Al-4V titanium rod, GR5 titanium rod its special characteristics can:
(1)GR5 titanium rod Ti6A14V belongs to α+β type alloy and is widely used.
(2)GR5 titanium rod has good process performance, and its conventional thermal deformation is carried out in the two-phase zone, and the deformation amount must be greater than 50% in order to transform the coarse original westenite structure into an isaemic structure.
(3) GR5 titanium alloy rod, after deformation processing, according to different needs, can be used stress relief annealing (600℃ insulation, air cooling), ordinary annealing (700 to 800℃ insulation, air cooling), recrystallization annealing (940℃ insulation after furnace cooling to 480℃ air cooling) and double annealing (940℃ insulation air cooling +700℃ insulation air cooling) and other heat treatment processes. The microstructure obtained by stress relief annealing and ordinary annealing is non-recrystallization or partial recrystallization, and the strength is higher. After recrystallization annealing, the equiaxed α+ intergranular p structure was obtained with good plasticity. The equiaxial α+β structure obtained by double annealing is close to the bistate structure, and has good comprehensive properties (about 900-1000MPa, 10% δ, 35% ~ 45% ψ).
(4) GR5titanium rod for enhanced heat treatment, the strength can be increased by 20%-30%. It is generally believed that aging at 850-950℃ can obtain the proper microstructure and better synthesizing properties of the primary α. The hardenability of TC4 alloy is poor, and the cross section of parts with enhanced heat treatment is generally not more than 40mm.
(5) GR5 titanium rod alloy has good weldability, and the temperature in the weld zone is not less than 90% of the matrix; Plasticity is also similar to that of secondary metal.
(6) The corrosion resistance of GR5 titanium alloy rod is close to pure titanium, and it can work for a long time below 400 ° C, and the short-time working temperature can reach 700-750 ° C. When the oxygen and nitrogen content in the alloy is low, the TC4ELI alloy can also maintain good plasticity at -196℃, and can be used to make low-temperature high-pressure vessels.
Titanium alloys are used in some large factories to improve the processing efficiency of titanium alloys with liquid nitrogen processing cooling. In addition, the tiny particles of titanium alloy debris cut down during processing will burn at a temperature of about 200 degrees if the cooling is not good. Its processing cost is very high, titanium alloy material is recognized as one of the most difficult materials in the machining industry.
Wisdom tianium produce all kinds of titanium rod in GR1 GR2 GR5 and exported to overseas all the year round. Except titaium rod and forgings, we also produce titanium hardware and cnc parts. Welcome inquiry!
