Extrusion

TL;DR: Extrusion is a process for shaping aluminum alloys into various forms, including rods, tubes, and sheets. It involves forcing molten alloy through a die, resulting in a shaped cross-section. The article covers design, processing, optimization, and metallurgy aspects of extrusion.

Abstract: The article will provide the reader with practical aspects of extrusion as well as an overview of the theoretical work and current challenges of this important aluminum alloy processing technology. This article is divided into three main sections: basic parameters for designing a section or die, an overview of extrusion processing, and optimization of productivity, cost and quality. Specific topical coverage includes: basic extrusion parameters, manufacturing of extrusions process review, productivity, quality including dimensional stability, surface quality, corrosion, cracking and tearing, product development and design, overview of the metallurgy of the extrusion process, numerical analyses and more.
