As a global supplier of high-grade aluminum products, sasaaluminum provides precision-engineered 6060 aluminum bars designed to meet the stringent requirements of extrusion-based manufacturing.
This article explores how sasaaluminum’s 6060 aluminum bars enable superior results in precision extrusion projects, highlighting their properties, production quality, and wide range of applications.
1. Understanding Precision Extrusion and Its Importance
Precision extrusion is a manufacturing process in which aluminum is forced through a die to produce profiles with specific cross-sectional shapes. The success of this process depends on several factors:
-
Alloy composition and purity
-
Consistency of billet temperature and microstructure
-
Dimensional accuracy and surface smoothness
The use of 6060 aluminum bars in extrusion ensures excellent formability, machinability, and surface finish, making them suitable for high-precision products where even minor variations are unacceptable — such as architectural frameworks, electronic housings, and automotive trims.
2. Overview of 6060 Aluminum Alloy
6060 aluminum belongs to the Al-Mg-Si series, which offers medium strength, excellent corrosion resistance, and outstanding extrusion performance. It is closely related to alloy 6063 but provides better extrudability and superior surface finish—ideal for thin-walled, intricate profiles.
