　GR5钛合金又名TC4钛合金，也叫它6Al4V,这是用途最广的一种钛金属，通常我们使用的钛合金就指它。它拥有良好的前度和延伸率。
GR5,TC4钛合金的十大性能
1、密度小，比强度高
金属钛的密度为4.51g/立方厘米，高于铝而低于钢、铜、镍，但比强度位于金属之首。
2、耐腐蚀性能
钛是一种非常活泼的金属，其平衡电位很低，在介质中的热力学腐蚀倾向大。但实际上钛在许多介质中很稳定，如钛在氧化性、中性和弱还原性等介质中是耐腐蚀的。
为了提高钛的耐蚀性，研究出氧化、电镀、等离子喷涂、离子氮化、离子注入和激光处理等表面处理技术，对钛的氧化膜起到了增强保护性作用，获得了所希望的耐腐蚀效果。针对在硫酸、盐酸、甲胺溶液、高温湿氯气和高温氯化物等生产中对金属材料的需要 ，开发出钛钼、钛-钯、钛-钼-镍等一系列耐蚀钛合金。钛铸件使用了钛-32钼合金，对常发生缝隙腐蚀或点蚀的环境使用了钛-0.3钼-0.8镍合金或钛设备的局部使用了钛-0.2钯合金，均获得了很好的使用效果。
3、耐热性能好
新型钛合金可在600℃或更高的温度下长期使用。
4、耐低温性能好
钛合金TA7（Ti-5Al-2.5Sn），TC4(Ti-6Al-4V）和Ti-2.5Zr-1.5Mo等为代表的低温钛合金，其强度随温度的降低而提高，但塑性变化却不大。在-196-253℃低温下保持较好的延性及韧性，避免了金属冷脆性，是低温容器，贮箱等设备的理想材料。
5、抗阻尼性能强
金属钛受到机械振动、电振动后，与钢、铜金属相比，其自身振动衰减时间最长。利用钛的这一性能可作音叉、医学上的超声粉碎机振动元件和高级音响扬声器的振动薄膜等。
6、无磁性、无毒
钛是无磁性金属，在很大的磁场中也不会被磁化，无毒且与人体组织及血液有好的相溶性，所以被医疗界采用。
7、抗拉强度与其屈服强度接近
钛的这一性能说明了其屈强比（抗拉强度/屈服强度）高，表示了金属钛材料在成形时塑性变形差。由于钛的屈服极限与弹性模量的比值大，使钛成型时的回弹能力大。
8、换热性能好
金属钛的导热系数虽然比碳钢和铜低，但由于钛优异的耐腐蚀性能，所以壁厚可以大大减薄，而且表面与蒸汽的换热方式为滴状冷凝，减少了热组，太表面不结垢也可减少热阻，使钛的换热性能显著提高。
9、弹性模量低
钛的弹性模量在常温时为106.4GPa，为钢的57%。
10、吸气性能
钛是一种化学性质非常活泼的金属，在高温下可与许多元素和化合物发生反应。钛吸气主要指高温下

与碳、氢、氮、氧发生反应。

GR5 Titanium ten properties
GR5 titanium alloy, also known as TC4 titanium alloy, also known as 6Al4V, which is the most commonly used type of titanium, titanium alloy we usually refer to it. It has a great pre-and extension rate.
GR5 Titanium top ten properties
1, low density, high strength
Titanium metal density of 4.51g / cubic centimetres, higher than the aluminum and lower than steel, copper, nickel, but the intensity in the first metal.
2, corrosion resistance
Titanium is a very lively metal with a very low equilibrium potential and a high tendency for thermodynamic corrosion in the medium. However, titanium is actually very stable in many media, such as titanium, which is resistant to corrosion in media such as oxidizing, neutral and weakly reducing.
In order to improve the corrosion resistance of titanium, surface treatment technologies such as oxidation, electroplating, plasma spraying, ion nitriding, ion implantation and laser treatment have been developed to enhance the protective effect of the titanium oxide film and obtain the desired corrosion resistance effect. In response to the need for metal materials in the production of sulfuric acid, hydrochloric acid, methylamine solution, high temperature wet chlorine and high temperature chloride, a series of corrosion resistant titanium alloys such as titanium molybdenum, titanium-palladium, titanium-molybdenum-nickel have been developed. Titanium-32 molybdenum alloy is used for titanium casting, and titanium-0.2 molybdenum-0.8 nickel alloy or titanium equipment is used for titanium-0.2 palladium alloy for the environment where crevice corrosion or pitting corrosion often occurs, and both are well utilized effect.
3, good heat resistance
The new titanium alloy can be long-term use at 600 or higher temperature.
4, low-temperature performance is good
Titanium alloy TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V) and Ti-2.5Zr-1.5Mo and other low temperature titanium alloy represented by its strength decreases with decreasing temperature, but the plasticity is not Big. In the -196-253 low temperature to maintain good ductility and toughness, to avoid the metal cold brittleness, low temperature containers, tanks and other equipment ideal material.
5, anti-damping performance
Titanium metal by mechanical vibration, electrical vibration, compared with steel, copper metal, the longest vibration decay time. The use of titanium for this performance can be invoked as a tuning fork, medical ultrasonic vibration elements and advanced audio speakers vibrating membrane.
6, non-magnetic, non-toxic
Titanium is non-magnetic metal that cannot be magnetized in a large magnetic field. It is non-toxic and has excellent compatibility with human tissues and blood. Therefore, titanium is employed in the medical field.
7, the tensile strength and yield strength close to
This property of titanium shows that its yield ratio (tensile strength / yield strength) is soaring,

indicating that the metallic titanium material has poor plastic deformation upon forming. Due to the titanium yield strength and elastic modulus of the ratio of fat, the resilience of titanium molding large.
8, good heat transfer performance
Although the thermal conductivity of titanium metal than carbon steel and copper is low, but because of titanium excellent corrosion resistance, so the wall thickness can be greatly reduced, and the surface and steam heat transfer mode drops condensate, reducing the heat group, too the surface Not scaling can also reduce the thermal resistance, so that the heat transfer performance of titanium significantly improved.
9, low modulus of elasticity
The modulus of elasticity of titanium is 106.4 GPa at room temperature, which is 57% of the steel.
10, inspiratory performance
Titanium is a chemically very reactive metal that reacts with many elements and compounds at elevated temperatures. Titanium suction mainly refers to elevated temperature and carbon, hydrogen, nitrogen, oxygen reaction.
