2007 Usinage Aluminium

Aperçu

L'alliage d'aluminium 2007, un alliage d'aluminium à copeaux courts, a une teneur en cuivre de 3,3 à 4,61 TP3T, ce qui lui confère une faible soudabilité et une faible résistance à la corrosion. Il est particulièrement utilisé pour la production de pièces tournées en raison de son excellente usinabilité et de son excellente capacité de traitement thermique, telles que les rondelles, les boulons, les écrous et autres kits du secteur. automobile l'industrie, et plus encore.

Qu'est-ce que l'Aluminium 2007 ?

Aluminum alloy 2007 is a high-strength aluminum alloy with main composition of aluminum, copper and some other elements. It represents the 2000 series of aluminum alloys with excellent mechanical properties and machinability. Alloying of aluminum 2007 with copper improves its strength properties without harming its machinability. This alloy is one of the most common base materials used in those applications requiring high strength and excellent machinability, such as in the production of precision components, fasteners, and fittings in the aerospace, automotive, and industrial machinery industries. Moreover, aluminum 2007 has excellent corrosion resistance, allowing it use in different environments.

Quelles sont les caractéristiques communes des alliages d’aluminium de la série 2000 ?

The 2000-series aluminum alloys possess several beneficial features, such as high strength and good machinability, that have ensured their use in fields where structural integrity and stiffness are vital. The combination of remarkable strength-to-weight ratios, however, these materials lack corrosion resistance to a degree that other aluminum series will provide. Therefore, they are cold-rolled so that during heat treatment, hardening through heat treatment processes could be done. In spite of their high copper content, which can be a cause for concern in terms of weldability, they have wide applications in aerospace, automotive and structural engineering. With their usage ranging from aircraft components to automotive wheels, where high strength and stiffness are critical requirements, their importance cannot be over-emphasized.

L'influence de la composition sur les propriétés de l'aluminium 2007

The performance characteristics (corrosion resistance, the strength-to-weight ratio, formability, etc.) primarily depend on the composition of the aluminum alloy 2007 which is the combination of aluminum and copper-based on the reinforcements of trace elements like magnesium, manganese, and silicon. Copper is the most important alloying component of the alloy, and evidently, the enhancement of strength of the alloy under the presence of heat is significant. Beyond other additions, impurities, and trace elements can modify properties like machinability, corrosion resistance, and mechanical strength. Apart from this heat treatment additionally improves mechanical characteristics via precipitation of the strengthening phases in the microstructure. Generally, exactness of modulation of composition and processing properties is highly critical to specify the characteristics of 2007 aluminum so that it perfectly meets specific application and hinders the degradation of desired properties in use situations.

Défis rencontrés dans le traitement de l'aluminium 2007

Due to the high copper content of this aluminum alloy 2007, it can be difficult to process it. Machining complications such as tool wear and poor surface finish happen from a presence of copper which means the cutting parameters and the methods of chip control need to be handled with special care. Heat treatment must be carefully regulated to obtain its specified strength properties without excessive deformation. Although welding creates trouble, it is of paramount importance to use some unique procedures so as to crack the weld. The meet of these concerns is achieved through application of quality measures such as process planning, tool selection, and parameter optimization which result in the production of good quality aluminum 2007.
