For the high-altitude, high-speed operating environment of aircraft, customized forgings must possess excellent mechanical properties: ① Fuselage frame beams: Custom-forged "large-size irregular beams" (up to 5m in length, 300×200mm in cross-section), made of 2024-T351 aluminum alloy (tensile strength ≥470MPa, fracture toughness ≥45MPa・m¹/²), using a "die forging + tensile straightening" process, with a straightness error ≤0.5mm/m, ensuring the stability of the fuselage structure; ② Wing joints: Custom-made "multi-directional forged joints" to achieve "one-forging," replacing the traditional split welded structure, increasing fatigue life to 10⁷ cycles without cracks, adapting to the vibration and impact of frequent takeoffs and landings; ③ Landing gear components: Custom-made "high-strength forged piston rods" according to the aircraft's load (e.g., 10 tons, 20 tons), made of 7050-T7451 aluminum alloy. Aluminum alloy (tensile strength ≥510MPa, yield strength ≥455MPa), with hard anodizing treatment (film thickness ≥50μm), improves wear resistance by 50%, meeting the wear requirements of frequent landing gear retraction and extension. Aero Engine Components: Engine components need to withstand high temperatures and pressures. Customized forged aluminum alloy parts can meet the requirements of precision and durability: ① Engine compressor blades: Customized "thin irregular blades" (thinnest part ≤2mm), using "precision die forging + CNC milling" process, blade profile tolerance controlled within ±0.05mm, ensuring smooth airflow. The material is 6061-T651 aluminum alloy, with a strength retention rate ≥90% at 150℃; ② Engine casing: Customized "annular casing" (inner diameter up to 1.2m) according to engine power, using "ring forging" process, wall thickness uniformity error ≤0.3mm, surface roughness Ra≤1.6μm, meeting the airtightness requirements of high-speed engine operation. (III) Industrial Machinery Sector: Adapting Heavy Load and Durability Requirements Industrial machinery (such as construction machinery and machine tools) has a prominent demand for "heavy load, wear resistance, and impact resistance" in its components. Customized aluminum alloy forging products can improve component lifespan through material and process optimization: Construction Machinery Components For the heavy load conditions of excavators and loaders, customized forgings can withstand high-strength loads: ① Excavator boom pin: Customized "large-diameter forged pin" (diameter up to 100mm, length 500mm), made of 6082-T6 aluminum alloy, surface hardened (hardness HRC30-35), compressive strength ≥280MPa, capable of withstanding loads exceeding 100kN during excavation without deformation; ② Loader bucket connecting rod: Customized "irregular forged connecting rod," using a combination of "free forging + die forging" to achieve a complex bending structure, tensile strength ≥320MPa, and lighter weight than steel connecting rods. 30%, reducing the energy consumption of loader operation; ③ Crane hook beam: "Arc beam" is customized according to the lifting capacity (such as 5 tons, 10 tons), and the material is 7075-T6 aluminum alloy. The internal stress is eliminated by "isothermal forging" process, and the fatigue strength is ≥180MPa, ensuring no cracks during long-term heavy-load operation.
