APWORKS, a specialist in aerospace 3D printing, has announced that its aluminum alloy, Scalmalloy, has been added to the Formula 1 regulations as an approved AM material by theFIA(Fédération Internationale de l’Automobile). The high strength alloy was originally developed by APWORKS and its parent companyAirbusfor aerospace components but has since found its uses in other high performance applications such as motorsports.
APWorks首席产品官Jonathan Meyer指出：“我们很自豪地在批准的材料清单中看到Scalmalloy。Scalmalloy仍然是市场上所有其他可加工铝合金的头部和肩膀，由于其航空航天的血统，其性能得到了对设计信心的所有必要证据的支持。”
高强度，低密度
Scalmalloy是铝，镁和扫描岩的混合物，具有非常令人印象深刻的机械性能。该材料能够保持高抗拉强度（520 MPa）和屈服强度（480 MPa），尽管其密度相对较低2.67 g/cm³。它的延展性也很棒，年轻的模量为70 GPA，伸长率为13％。合金自然抗腐蚀，并在热老化时表现出高度的微结构稳定性。
根据APWorks的说法，Scalmalloy实际上是专门用于与AM技术一起使用的，并补充了制造过程的特征。
赛车运动的Scalmalloy
该公司将Scalmalloy的适合性归因于其所需强度，延展性和密度的全部贸易性质。加上AM授予的设计自由，APWorks可以自由地创建具有优化拓扑的轻质结构组件 - 该公司的专业知识领域。这意味着他们生产的零件通常具有更好的质量和压力分布，同时仍保持在调节重量限制之内，从而为F1驱动程序提供了刮擦这些额外秒数所需的竞争优势。
迈耶总结说：“我们已经期待着进一步扩大应用程序，因为我们的赛车客户获得了信心在日益关键的应用程序中应用ScalMalloy的信心。”
这不是APWORKS”automotiv第一回合e sector, as the company has previously 3D printed atitanium part for the 2020 Bugatti Chiron Pur Sport. The exhaust tailpipe was 3D printed to make it more lightweight and temperature resistant, with thin walls and a carefully optimized geometry. Back in the aerospace sector, the company also partnered withmetal 3D printer manufacturerAdditive Industriestoqualify components at Additive Industries’ new Process & Application Development Centerlocated near Bristol, UK. The duo has since been its combined resources to advance AM series production for aerospace systems.
