Customized TC4 titanium alloy plate, titanium ring, titanium alloy tube, complete specifications
1. Product name: Titanium alloy plate, TC4/GR5 titanium plate
Performance of titanium alloy plate:
(1) For semi-automatic cutting, the guide rail should be placed on the plane of the titanium plate, and then the cutting machine should be placed on the guide rail. Please note that the order cannot be reversed.
(2) The cutting parameters should be appropriate and should be reasonably determined according to the thickness of the titanium plate to obtain a good cutting effect.
(3) Check whether the nozzle gas is unblocked, if it is blocked, unlock it.
(4) Before cutting the titanium plate, it is necessary to clean the surface and leave a certain space to help the slag blow out.
(5) The distance between the cutting nozzle and the surface of the titanium plate should be appropriate. Too close or too far is not good.
(6) The preheating of the titanium plate should be sufficient to avoid affecting the cutting process.
(7) If you want to cut workpieces of different sizes, you should cut small pieces first, and then cut large pieces.
According to the data of the titanium alloy plate manufacturer, titanium is a new type of metal. The performance of titanium is related to the content of impurities such as carbon, nitrogen, hydrogen and oxygen. The impurity content of pure titanium iodide does not exceed 0.1%, but the strength is low and the plasticity is high. The properties of 99.5% industrial pure titanium are: density ρ= 4.5g/cm3, melting point 1725°C, thermal conductivity λ= 15.24W/(mK), tensile strength σb= 539MPa, elongation δ= 25%, and section shrinkage Rate ψ = 25%, elastic modulus E = 1.078×105MPa, hardness HB195.
(1) Higher than intensity
The density of titanium alloy is usually about 4.5g/cm3, which is only 60% of steel. The strength of pure titanium is close to that of ordinary steel. Some high-strength titanium alloys exceed the strength of many alloy structural steels. Therefore, the specific strength (strength/density) of titanium alloy is much greater than that of other metal structural materials. It can produce parts with high unit strength, good rigidity and light weight. Currently, titanium alloys are used for aircraft engine parts, skeletons, skins, fasteners and landing gear.
(2) High thermal strength
The working temperature is hundreds of degrees higher than that of aluminum alloy, and it can maintain the required strength at moderate temperatures. Two types of titanium alloys can work for a long time at a temperature of 450 to 500°C. Both types of titanium alloys are still high in the range of 150 to 500°C. The aluminum alloy decreases significantly at 150°C. The working temperature of titanium alloy can reach 500°C, while the working temperature of aluminum alloy can be lower than 200°C.
(3) Good corrosion resistance
Titanium alloy can work in humid atmosphere and sea water, and its corrosion resistance is far better than stainless steel. It is particularly resistant to pitting, acid and stress corrosion. Organic compounds such as alkali, chloride, chlorine, nitric acid and sulfuric acid have excellent corrosion resistance. However, titanium has poor resistance to reducing oxygen and chromium salt media.
(4) Good low temperature performance
Titanium alloys can maintain their mechanical properties at low and ultra-low temperatures. The low temperature performance of titanium alloys with very low clearance properties (such as TA7) can still maintain a certain degree of plasticity at -253°C. Therefore, titanium alloy is also an important low-temperature structural material.
(5) High chemical activity
Titanium has great chemical activity, and produces a strong chemical reaction with O, N, H, CO, CO2, water vapor, ammonia, etc. in the atmosphere. When the carbon content is greater than 0.2%, hard TiC will be formed in the titanium alloy; at higher temperatures, a TiN hard surface layer will also be formed when interacting with nitrogen. When the temperature is higher than 600°C, titanium absorbs oxygen to form a hardened layer with high hardness. The increase in hydrogen content will also form a brittle layer. The depth of the hard and brittle surface layer produced by absorbing gas can reach 0.1 to 0.15 mm, and the degree of hardening is 20% to 30%. Titanium also has a great chemical affinity and is easy to adhere to the friction surface.
(6) The thermal conductivity is small, and the modulus of elasticity is small
The thermal conductivity of titanium is 15.24W/(m.K) about 1/4 of nickel, 1/5 of iron, and 1/14 of aluminum. The thermal conductivity of various titanium alloys is about 50% lower than that of titanium. The modulus of elasticity of titanium alloy is about 1/2 of that of steel, so it has poor rigidity and is easy to deform. Not suitable for making slender rods and thin-walled parts. The springback of the machined surface during the cutting process is very large, about 2 to 3 times, leading to severe friction, adhesion, and bonding wear.
