AlCu4SiMg Round Bars / ENAW AlCu4SiMg Round Bars / ENAW 2014 Round Bars
AlCu4SiMg Round Bars is an Aluminium-Copper-Silicon-Magnesium Alloy round bar used for engineering, machining, structural and industrial applications where a combination of strength, machinability, corrosion resistance and lightweight construction is required. AlCu4SiMg belongs to the family of heat-treatable aluminium alloys and can be supplied in different tempers and dimensions depending on the application and required mechanical properties.
AlCu4SiMg Aluminium Round Bars are available in different diameters and lengths and can be supplied in standard, cut-to-length or customized sizes. These aluminium alloy bars are commonly selected for components where lower density than steel is desirable while maintaining useful mechanical strength and good machinability.
AlCu4SiMg is an aluminium alloy containing copper, silicon and magnesium as major alloying elements. The addition of copper and magnesium provides the alloy with the ability to achieve improved strength through heat treatment, while silicon contributes to casting and processing characteristics.
AlCu4SiMg Round Bar can be machined into shafts, bushes, spacers, housings, brackets, mechanical components and other precision-engineered parts. Depending on the specification and condition supplied, the material can be selected for applications requiring a balance of weight, strength and machinability.
Textron Steel and Alloys supplies AlCu4SiMg Round Bars for industrial and engineering requirements in India and overseas markets.
