These alloys are known for their excellent oxidation resistance, high-temperature strength, and superior mechanical properties, making them essential for demanding industries like aviation, aerospace, and power generation. Key Features of GH2747, GH747, and Nimonic80A Alloy Bars High-Temperature Strength: GH2747, GH747, and Nimonic80A alloys can withstand extreme temperatures up to 1000°C and beyond, making them ideal for components exposed to high heat, such as turbine blades and engine rotors. Corrosion and Oxidation Resistance: These alloys excel in resisting oxidation and corrosion, even under high-temperature and high-pressure conditions, ensuring the longevity and reliability of components in aggressive environments. Good Creep Resistance: GH2747 and other similar alloys exhibit excellent creep resistance, ensuring minimal deformation under sustained high temperatures and loads. Superior Mechanical Properties: These alloys have outstanding tensile strength, yield strength, and fatigue resistance, which are critical for components subjected to dynamic stresses. Weldability and Machinability: The alloys are highly weldable and machinable, allowing for ease of fabrication and customization to meet the precise needs of aerospace and industrial applications. Manufacturing Process of GH2747 Alloy Bars The manufacturing process of GH2747, GH747, and Nimonic80A alloys involves several stages to ensure the final product meets the rigorous demands of high- temperature applications: Melting: High-purity raw materials are melted in an electric arc or induction furnace. The molten metal is refined to remove impurities and achieve the desired chemical composition. Casting: The alloy is cast into ingots. These ingots are then heat-treated to homogenize the material and eliminate segregation. Forging: The ingots are hot-forged at temperatures above 1100°C, which refines the microstructure and improves the mechanical properties of the alloy. Hot Rolling: After forging, the material is hot-rolled to reduce thickness and achieve the required final dimensions. Annealing: The rolled bars are annealed at temperatures between 900-950°C to relieve internal stresses and improve ductility. Finishing: The final step involves cutting the bars to the required lengths and applying necessary surface treatments, such as grinding or polishing, to protect the alloy from environmental factors.

Brightstar specializes in the processing of medium-sized and small parts with over 15 years of CNC machining experience and a wealth of process parameters and case studies. As one stop CNC Machining Service, we can quickly respond to the machining needs of various complex parts while ensuring consistent machining quality. Our team of process engineers and senior technicians, each with over 10 years of experience, provides comprehensive technical support, from design optimization and programming to machining implementation. Drawing Conversion & Programming After receiving customer drawings, our technical team first performs 3D modeling using specialized software such as UG and Mastercam, converting 2D drawings into a solid model. During the modeling process, they focus on key part dimensions, tolerance requirements, and assembly relationships to ensure the model fully complies with customer requirements. The programming phase utilizes parametric programming technology to automatically generate machining programs based on the part's machining process. For complex curved parts, the CAM software's toolpath optimization function reduces idle tool travel and improves machining efficiency. Furthermore, machining programs are verified using a virtual simulation system to check for tool collisions with parts and fixtures, eliminating machining risks in advance. Once programming is complete, the program is uploaded to a cloud database for easy access by various machining equipment.

In our factory, there are 12 units of DMU 950 and Hermle 5-axis machining equipment, which have held significant advantages in the field of precision machining. Equipped with a ruby probe automatic compensator, they can monitor the movement state of each axis of the CNC machine center and the tool position in real-time during the machining process. When the machine tool has slight deviations due to factors such as thermal deformation and mechanical wear, the ruby automatic compensator can quickly capture these changes and feed back the deviation data to the machine control system. The system then makes precise adjustments to the tool path or coordinate axis position according to the preset algorithm, ensuring that the machining always maintains a high-precision level. 5-axis Equipment Parameter Maximum stroke:  950*850*650 mm Rotate speed:  20,000 rpm Maximum workpiece size :  1200*1040*650mm Machining Accuracy:  ±0.01/100mm
