Aluminum Forged Products for Aerospace Applications
Share
Used in Spacecraft and Aircraft Parts, from Small to Large
Our forged parts for spacecraft and aircraft benefit from our long years of aircraft technology development. Our sophisticated technologies and leading-edge R&D capabilities support our global leadership, backed by some of the largest and most advanced production facilities available, in technological innovation in the aerospace field.
Features
- 15,000-ton forging press handles items weighing up to 6,000 kg.
- Precision forging (gradient of 0° on the exterior wall) minimizes the amount of machining required after forging.
- Our fully-integrated manufacturing system—from ingots to forging, heat treatment, finish processing and testing—enables us to meet the high quality standards needed on aircraft materials.
Applications
- Aircraft, rockets and other segments of the aerospace field
Examples of large forging
Large aluminum alloy forging are desired for their light weight, strength and high reliability. High-temperature, high-pressure forging is used to produce frames for aircraft fuselages and rings for rocket walls.
Examples of die forging products
Die forging uses dies close to the final product shape. This method eliminates machining or reduces it to a minimum. Products show low variation in quality and dimensions—a key characteristic that suits the process for mass production.
