Spring is a relatively special part, it is widely used in various fields of national production and life, such as cars, motorcycles, bicycles and other vehicles, computers, clocks, light switches, toys, clamps and other daily necessities are used to spring, mainly play a role in shock absorption, energy storage.
Although the spring is only a small part, whether it is in an aircraft or other devices, once broken, it often causes the loss of some device or system function, and even leads to serious consequences. At present, the most widely used spring material is steel, which requires steel to have a high strength and elastic limit. However, with the increase of strength and hardness of steel, the sensitivity to stress concentration and the tendency of spontaneous fracture under constant load also increase. If the hardness is too low, the return ability of the spring will be reduced, or even fail, and the function of the spring will be lost.
In recent years, titanium alloy has become a new choice of spring materials because of its high specific strength, low elastic modulus and good corrosion resistance. Compared with steel Springs, Titanium Alloy Grade 5 Springs have the advantages of light weight, small size and high resonance frequency, and their density and elastic modulus are only half that of steel springs, while their strength is almost the same as that of steel springs. Due to these advantages, titanium springs can be designed to be smaller in diameter, fewer turns and greatly reduced in weight than steel springs in practical applications. Among them, the high strength β titanium alloy is the best material for manufacturing springs.
Titanium Alloy Grade 5 Springs are characterized by low density, high strength, excellent corrosion resistance, fatigue resistance and low shear modulus, and can be widely used in aerospace, motor racing (on Formula 1 or racing motorcycles), petrochemical, mining, food processing or medical fields.
