With the COMAC C919 entering mass production and the C929 wide-body jet advancing in development, demand for aerospace-grade aluminum alloy sheet is experiencing structural growth. This guide targets industrial procurement decision-makers, providing an overview of market dynamics, alloy grade selection, and emerging domestic supply chain opportunities.
According to COMAC forecasts, China’s commercial fleet will require over 6,000 new aircraft in the next decade, translating to aerospace aluminum structural component procurement valued in the hundreds of billions of RMB. Civil-military integration policies continue to deepen, enabling aluminum material enterprises previously limited to military supply chains to obtain airworthiness certifications and enter commercial aviation procurement catalogs.
Key growth drivers:
Aerospace aluminum alloy sheets primarily use 2xxx (Al-Cu) and 7xxx (Al-Zn-Mg-Cu) high-strength alloys, with 6xxx (Al-Mg-Si) alloys for non-structural components.
| Grade Series | Typical Grades | Key Characteristics | Typical Applications |
|---|---|---|---|
| 2xxx (Al-Cu) | 2024, 2124 | High strength, good workability, heat resistance | Fuselage skin, rivets, fasteners |
| 6xxx (Al-Mg-Si) | 6061, 6082 | Medium strength, excellent weldability, corrosion resistance | Floor beams, frames, non-structural parts |
| 7xxx (Al-Zn-Mg-Cu) | 7075, 7055, 7150 | Ultra-high strength, good machinability | Wing skins, spar structures, landing gear attachments |
China’s aerospace aluminum alloy sheet supply chain has built a relatively complete domestic capability:
Procurement Note: Prioritize grades already listed on the COMAC Approved Materials List (AML). Confirm airworthiness documentation (CAAC-PMA or OEM certificates) completeness and validity with suppliers.
Aerospace aluminum alloy sheet is benefiting from three structural growth drivers: mass production of domestically-built commercial jets, deepening civil-military integration, and rapid UAV market expansion. 2xxx and 7xxx high-strength aluminum alloys are procurement priorities. Domestic suppliers have established substitution capabilities for key grades. Procurement decision-makers should actively advance domestic supplier qualification, while ensuring airworthiness certification and batch quality consistency, to optimize procurement costs and supply chain resilience.

随着C919大型客机进入批量化生产阶段、C929宽体客机研发加速推进，航空航天铝合金板材的市场需求正经历结构性增长。本文面向工业采购决策者，解析航空航天铝合金结构件的市场格局、主流牌号选型及国产供应链机会。
据中国商飞预测，未来10年国内民航机队新增需求将超过6000架次，对应航空铝合金结构件采购规模达数千亿元量级。军民融合政策持续深化，大量原本局限于军品供应链的铝合金材料企业获得适航认证，进入民航采购目录。
关键驱动因素：
航空航天铝合金板材主要使用2系（Al-Cu系）和7系（Al-Zn-Mg-Cu系）高强度合金，部分非承力构件使用6系（Al-Mg-Si）合金。
| 牌号系列 | 典型牌号 | 主要特征 | 典型应用 |
|---|---|---|---|
| 2系（Al-Cu） | 2024、2124 | 高强度、良好加工性、耐热性 | 机身蒙皮、铆钉、紧固件 |
| 6系（Al-Mg-Si） | 6061、6082 | 中等强度、优异焊接性、耐蚀性 | 地板梁、隔框、非承力结构件 |
| 7系（Al-Zn-Mg-Cu） | 7075、7055、7150 | 超高强度、优良加工性 | 机翼上下壁板、翼梁、起落架连接件 |
航空航天用铝合金板材采购需重点关注以下技术参数：
国内航空航天铝合金板材供应链已形成较完整的国产化体系：
采购建议：优先选用已列入中国商飞材料采购目录（AML）的牌号，并与供应商确认适航文件（CAAC-PMA或原厂证书）的完整性与时效性。
航空航天铝合金板材正受益于国产大飞机量产、军民融合深化和无人机市场扩张三重驱动力。2系和7系高强度铝合金板材是采购重点，国产供应链在关键牌号上已具备替代能力，采购决策者应在确保适航认证和批次质量一致性的前提下，积极推进国内供应商的认证导入，优化采购成本与供应链韧性。

Carbon fiber prepreg forms the backbone of modern lightweight aerospace and high-performance structures. Among the most specified grades is Toray T800-series intermediate-modulus prepreg. Below we answer the questions engineers and procurement teams ask most often.
Toray T800 is an intermediate-modulus carbon fiber impregnated with a thermosetting resin, most commonly an aerospace-grade epoxy, in a precisely controlled, pre-metered form called prepreg. The resin is advanced to a B-stage, so the material arrives ready for lay-up and cure. It pairs T800 fiber high tensile strength, around 5.5 GPa, with the handling convenience of a pre-impregnated sheet, making it a workhorse for high-performance structural composites.
T300 is a standard-modulus, heritage fiber valued for low cost and a long flight history. T700 delivers higher strength at a similar modulus. T800 belongs to the intermediate-modulus class: tensile strength near 5,490 MPa with modulus around 294 GPa. That is roughly 10 to 15 percent higher modulus and notably better damage tolerance than T700, at a moderate cost premium. For primary aircraft structures where stiffness-to-weight and fatigue resistance matter, T800 is usually the preferred choice.
With a standard 350-degree-Fahrenheit-cure epoxy, typical lamina properties are tensile strength 2,700 to 3,000 MPa in the zero-degree direction, tensile modulus 135 to 160 GPa, compressive strength 1,500 to 1,800 MPa, and fiber volume fraction 58 to 62 percent. Actual values depend on the resin system, cure cycle, and fiber areal weight. Always use the qualified laminate allowables from your material specification rather than fiber-only datasheet numbers.
Primary and secondary aerospace structures such as wing skins, fuselage frames, spars, and floor beams, plus spacecraft and satellite bus structures, and high-end sporting goods like bicycle frames and racing components. It is selected wherever a high strength-to-weight ratio and excellent fatigue performance are required.
T800 prepreg is temperature-sensitive. Store at minus 18 degrees Celsius with tight humidity control; typical freezer life is 6 to 12 months depending on the resin. During lay-up, work in a controlled cold chain: thaw sealed in original packaging to room temperature, about 12 to 24 hours, to prevent condensation, then use within the published out-time, commonly 30 days at ambient and 7 days after vacuum debagging. Track each roll lot and expiry meticulously.
Most aerospace T800 epoxies cure at 177 degrees Celsius under vacuum and autoclave pressure, typically 3 to 7 bar, with a defined ramp, dwell, and cool-down profile. Some out-of-autoclave systems cure at lower pressure. Follow the qualified cure cycle exactly, because deviation changes resin flow, void content, and final properties.
Require full traceability, fiber lot, resin lot, prepreg batch, a Certificate of Conformance, and ideally EN 9100 or AS9100 supplier qualification. For flight parts the material must be on a qualified products list and the laminate qualified per the airframe OEM specification. Request independent third-party verification, including mechanical coupon testing and non-destructive testing, for high-criticality buys.
Match the resin to service temperature, toughness, and processing needs. The 350-degree-F cure epoxy is the default for aerospace. A 250-degree-F system reduces cost and cycle time for secondary structures. Toughened epoxies improve impact and delamination resistance. Also consider tack and drape for hand lay-up versus automated fiber placement.
T800 prepreg costs more than T300 or T700 and carries longer lead times, often 8 to 16 weeks, because of aerospace qualification and batch production. Plan procurement early, qualify alternate sources, and buffer inventory against freezer-life expiry.
Handle with gloves in a ventilated area; uncured resin can cause skin sensitization. Follow the safety data sheet guidance and dispose of waste per local regulations.
