Common grades and forging of titanium alloys

Titanium alloy is a high-strength, lightweight, corrosion-resistant metal material. Due to its excellent properties, it is widely used in high-tech fields such as aviation, aerospace, medical treatment, and chemical industry. There are many models of titanium alloys, and different models have different properties and application areas. Let's take a look at the commonly used titanium alloy models:
1.Ti-6Al-4V
Ti-6Al-4V is the most commonly used titanium alloy and the one with the best performance. It has high strength, good toughness, and strong corrosion resistance, and can easily cope with high temperature, high pressure, and highly oxidizing environments. Therefore, Ti-6Al-4V is widely used in the aerospace field, such as manufacturing aircraft engines, missiles, satellites, etc.
2.Ti-5Al-2.5Sn
Ti-5Al-2.5Sn is a medium-strength titanium alloy with good corrosion resistance and weldability. Its strength and toughness are slightly lower than Ti-6Al-4V, but its weldability is better and can be processed using traditional welding methods. Therefore, Ti-5Al-2.5Sn is widely used in marine engineering, chemical industry, medical and other fields.

3. Ti-6Al-6V-2Sn
Ti-6Al-6V-2Sn is a high-strength, high-toughness titanium alloy with excellent corrosion resistance and oxidation resistance. Its strength and toughness are higher than Ti-6Al-4V and can be used in more harsh environments. Therefore, Ti-6Al-6V-2Sn is widely used in aerospace, nuclear industry and other fields.
4.Ti-3Al-8V-6Cr
Ti-3Al-8V-6Cr is a titanium alloy with good corrosion resistance and weldability. Its strength and toughness are slightly lower than Ti-6Al-4V, but its weldability is better and can be processed using traditional welding methods. Therefore, Ti-3Al-8V-6Cr is widely used in marine engineering, chemical industry, medical and other fields.
5.Ti-4Al-2.5Sn
Ti-4Al-2.5Sn is a titanium alloy with medium strength and good corrosion resistance. Its strength and toughness are slightly lower than Ti-6Al-4V, but its weldability is better and can be processed using traditional welding methods. Therefore, Ti-4Al-2.5Sn is widely used in marine engineering, chemical industry, medical and other fields.
What are the forging processes of titanium alloy plates? Titanium alloy forging is a very common process technology. Many companies have very high demand for plate forgings in forging processing. Titanium alloy plate forging has good corrosion resistance and stability. The forging process of titanium alloy plates is Necessary conditions for manufacturing high-quality forgings. Let's take a look at the titanium alloy plate forging process.
Heating: Put the titanium alloy plate into the furnace for heating to reach the forging temperature. Care must be taken to prevent oxidation and burning during the heating process.
Forging: Forging on a forging machine to form the desired shape and size. This step may need to be repeated as many times as necessary.
Heat treatment: Improve the mechanical properties of titanium alloys through heat treatment, including tensile strength, yield strength and elongation.
Cooling: The forged titanium alloy plate is cooled to stabilize its shape and size.
Surface treatment: As needed, titanium alloy plate forgings are polished, coated or pickled to enhance their corrosion resistance and aesthetics.
During low-temperature forging, the dimensional changes of the forgings are very small. When forged below 700°C, there is less oxide scale formation and no decarburization on the surface. Therefore, as long as the deformation energy is within the forming range, cold forging can easily achieve good dimensional accuracy and surface finish. As long as the temperature and lubrication and cooling are well controlled, warm forging below 700°C can also achieve good accuracy. During hot forging, since the deformation energy and deformation resistance are very small, large forgings with complex shapes can be forged. To obtain forgings with high dimensional accuracy, hot forging can be used in the temperature range of 900-1000°C. In addition, attention should be paid to improving the working environment of hot forging. The life of the forging die (hot forging is 2-5 thousand, warm forging is 10,000-20,000, cold forging is 2-50,000) is shorter than forging in other temperature ranges. Yes, but it has great freedom and low cost.
There are many titanium alloy forging processes. Each step requires strict quality control and continuous optimization of the performance of forgings. Choosing a professional forging processing manufacturer can further improve the forging quality of the product.
