Abstract

The invention provides an aircraft seat frame alloy material, the chemical element composition and mass percentage of the alloy material are: Ti: 0.21%~0.35%, Mn: 0.5%~1.05%, P: 0.02%~0.03%, Cu: 0.02%~0.05%, Si: 0.25%~0.55%, Cr: 12.0%~15.0%, Ni: 3.0%~9.0%, Zn: 0.13%~0.21%, V: 0.2%~0.3%, Co: 0.01%~0.03%, W: 0.02%~0.04%, Ce: 0.15%~0.30%, Lu: 0.15%~0.30%, and the rest is Al. The invention melts and casts under vacuum conditions, and the finished aircraft seat frame alloy material obtained through hot isostatic pressing has excellent compression resistance, corrosion resistance and high hardness.

Description

technical field [0001] The invention belongs to the field of aluminum-based alloys, and in particular relates to an aircraft seat frame alloy material. Background technique [0002] With the deepening of the globalization process and increasingly fierce competition, "flying in the air" has become the preferred mode of transportation for human beings. The seat is an extremely important structure in the entire structure of the aircraft and is an indispensable part. It provides work and life security and protection from damage for the occupants in the cabin. According to the predictions of Boeing, Airbus and Chinese authoritative organizations, China's civil aviation will add 1,200 1,588 aircrafts in the next 20 years, and the number of passenger seats will increase by 200,000 to 240,000, with an average annual increase of 10,000 to 12,000 passenger seats. chair. The number of passenger planes in China has increased dramatically, and seats have become a huge business opportu...
