Customized touch-to-type parts drone components

To most people, a “drone” is a specific type of unmanned aerial vehicle (UAV): a multi-rotor or multi-rotor vehicle. As the name suggests, these machines fly with downward directed thrust via two or more motor-driven propellers.

How about magnesium alloys used in drone parts

New magnesium-based materials are ideal for future aircraft because they are so light that they could significantly increase the range of these vehicles. They exhibit very good castability, are easy to machine, and can be formed into profiles or forgings for use as components in next-generation aircraft structures. In the case of a large number of the same parts, magnesium alloy high pressure die casting is significantly better than aluminum alloy high pressure die casting. This is due to the lower solubility of iron in magnesium, resulting in significantly longer tool/casting life. In addition, the mold filling time for high pressure die casting of magnesium alloys is reduced by approximately 30%. This is because of the lower density: aluminum alloys are about 50% heavier than magnesium alloys, which is a significant disadvantage of aluminum alloys, especially in the aerospace industry.

Im Wettbewerb mit Aluminiumlegierungen als Konstruktionsmaterialien haben Magnesiumlegierungen die Vorteile einer geringen Dichte, eines hohen Festigkeitsverhältnisses, besserer elektromagnetischer Abschirmeigenschaften und Gießbarkeit. Dies führt zur bevorzugten Verwendung von Magnesiumlegierungen in 3K-Komponenten (Computer-, Kommunikations- und Verbraucherprodukte), bei denen geringes Gewicht, Wärmeableitung und elektromagnetische Abschirmung entscheidend sind. Sie haben auch extrem breite Anwendungen in den Bereichen Automobil, Luft- und Raumfahrt, Outdoor-Sportarten usw.

Mit der hohen Integration in 3C wird es dringlicher, die beim Betrieb von elektronischen Bauteilen und Wärmetauschern entstehende übermäßige Wärme abzuführen, die durch Überhitzung oder Verformung zum Ausfall der Bauteile führt. Die Nachfrage nach Materialien mit hervorragender Wärmeableitung und mechanischen Eigenschaften steigt rasant. Die Auswahl von Materialien mit geeigneter Wärmeleitfähigkeit ist sehr wichtig, um die beste Leistung von Komponenten zu erzielen.

Mg-Legierungen weisen aufgrund ihrer geringeren Wärmekapazität und besseren Wärmeableitungswirkung als Al-Legierungen ein großes Potenzial als Wärmeableitungsmaterialien auf. In den letzten Jahrzehnten wurden einige Anstrengungen unternommen, um die Wärmeleitfähigkeit von Mg-Legierungen mit einem klaren Verständnis der grundlegenden Wärmeübertragung auf Mikro-, Nano- und sogar molekularer Ebene zu verbessern. 

Mit dem Ziel, eine Mg-Legierung zu entwickeln, die im Vergleich zu den üblicherweise verwendeten AZ91D-Magnesiumlegierungen eine deutlich verbesserte Wärmeleitfähigkeit bieten kann, baute Zhongmei gemeinsam mit dem weltweit führenden Experten Prof. Pan Fusheng von der Chongqing University und seinem Team das Research Institute of Magnesium Alloy Materials auf.

Das Forschungsinstitut führt weiterhin Experimente und Tests durch und hat beachtliche Erfolge erzielt
