The key component of industrial equipment-titanium alloy handle
In the process of using industrial equipment, a small handle seems inconspicuous, but it often plays an important role. Especially for some special industrial environments, such as aerospace, marine engineering and other fields, it is necessary to choose materials with strong corrosion resistance and high strength to make handles, and titanium alloy handles came into being.
1. What is a titanium alloy handle?
Titanium alloy handle is made of titanium-based alloy with other elements, and there are common models such as Ti6Al4V. Its density is generally around 4.5g/cm3, which is nearly half lighter than steel. However, the tensile strength can reach above 882MPa, which is close to that of steel. It also has good heat resistance and low temperature toughness, and still maintains good mechanical properties at MINUS 196℃.
Second, why choose titanium alloy as the handle material?
(1) Excellent corrosion resistance
Because it is easy to form a dense and stable oxide film on the surface of titanium alloy, even if this oxide film is destroyed, it can repair itself, so it shows good stability in seawater or chloride solution. In addition, it can resist the corrosion of various acid-base media, including hydrochloric acid, nitric acid, sulfuric acid and organic acids.
(2) High strength and low specific gravity
Compared with stainless steel or aluminum alloy, the weight under the same volume is smaller, which can effectively reduce the self-weight burden of the whole product and improve the stability and bearing capacity of the whole structure. At the same time, it has high yield point and ultimate tensile force, and can keep the shape unchanged under the condition of bearing large external force, ensuring the safety and reliability of users.
(3) Good processability
It is easy to be molded into various complex product parts under cold working or heat treatment conditions. For example, stamping, forging and welding can be applied to this kind of material. Coupled with its excellent conductivity and permeability, it has become one of the ideal choices for manufacturing precision instrument housings.
Third, the application field of titanium alloy handle
(1) Aerospace field
All kinds of switch buttons in aircraft need to be designed and produced with high quality materials, and titanium alloy has become the first choice because of its unique physical and chemical properties. For example, the locking device on the engine door is made of this material, which not only meets the strict weight reduction requirements of aircraft, but also ensures the safety and reliability during flight.
(2) Chemical industry
Many highly corrosive liquid or gas containers are equipped with handle parts specially used to open the lid. If ordinary metal is used, it is easy to rust, which will affect the service life and even cause safety accidents. Therefore, these occasions tend to use specially treated titanium alloy materials to build such accessories.
IV. Conclusion
To sum up, with the continuous improvement of scientific and technological level and the increasing market demand, titanium alloy guards will be paid more and more attention and widely used in the next few years. I hope the above content will help you!
