Titanium alloy 3D printing powder has been applied in aerospace and other fields
The quality of metal additive manufacturing parts is closely related to the characteristics of metal powder, including powder particle size, sphericity, flowability, loose density, etc. The demand for high-precision, high-quality, and ultra precision applications in fields such as aerospace, aviation, and healthcare has also raised higher requirements for the quality of metal 3D printing powders.
Based on in-depth market observation and long-term practice in metal additive manufacturing, Platinum Power has developed various titanium and titanium alloy powders, including TA1, TA15, TC4, TA18, TC21, in response to the special needs feedback from users over the years. These powders have been successfully applied in additive manufacturing fields such as aerospace.
The excellent comprehensive mechanical properties of TC4 can meet the powder performance requirements of aviation engines, and its high specific strength and lightweight characteristics provide support for blade weight reduction; The powder has high thermal stability and antioxidant properties, which can extend the lifespan of the blades and inspection intervals; At the same time, the interior of the parts adopts a hollow structure, which has a large design space and can achieve more diverse shapes, meeting the needs of various scenarios.
TC4 is a widely used titanium alloy material in the aerospace and medical fields. After being formed by selective laser melting (SLM) additive manufacturing equipment, the microstructure of the obtained components is uniform and dense, with the characteristic of rapid solidification. The tensile strength, yield strength, and elongation of printed parts are about 6-7%, 6-10%, and 55-60% higher than the forging index, respectively. Among them, 15~53 μ The technical specifications of m TC4 powder are shown in the table below.
The antenna bracket structure has undergone topology optimization and integrated design, achieving a 35% weight reduction compared to traditional machined components, alleviating stress concentration and reducing peak stress response by 6%. The internal dimensional accuracy of the parts is high, and the high specific strength and moderate high-temperature mechanical properties of TA15 titanium alloy make the parts have good load-bearing and stress capacity, meeting the requirements of safety critical applications such as aerospace.
TA15 belongs to high-temperature titanium alloy, with slightly higher room temperature mechanical properties and moderate high-temperature mechanical properties than TC4. It is mainly used for printing and forming of aerospace structural components and engine components. Platinum has independently developed TA15 powder, which has been used for the forming of multiple types of titanium alloy parts. The maximum size of the parts reaches 1000mm, and some products have been successfully delivered to customers, meeting the strict requirements of the aerospace industry.
