Aluminum Alloy Bars for Extrusion

The aluminum alloy bars from Transformación Puebla, S.A. de C.V. are specifically designed to feed aluminum profile extrusion processes. Measuring 7 inches (178 mm) in diameter and approximately 3.7 meters in length, our bars, also known in the industry as billets, are manufactured with chemical composition optimized to guarantee superior performance in the extrusion press. From our plant in San Pedro Cholula, Puebla, we serve leading aluminum profile extruders across Mexico.

The aluminum extrusion process is highly sensitive to the quality of the input material. A bar with inadequate chemical composition, excessive hydrogen content, or the presence of non-metallic inclusions can generate surface defects on the extruded profile, premature die wear, reduced extrusion speeds, and even profile breakage during the process. At Transformación Puebla we understand this criticality, and therefore subject every heat of bars to the same comprehensive metallurgical treatment that characterizes all our products: controlled melting, fluxing for oxide removal, rotary degassing with nitrogen to reduce dissolved hydrogen content to minimum levels, precise chemical composition adjustment, spectrometric verification with our ARL 3460, and liquid metal filtration prior to pouring.

The alloys we manufacture for extrusion span the families most used by Mexican extruders. The 6xxx series, particularly the 6063 and 6061 alloys, are in highest demand for architectural, structural, and industrial profiles. The 6063, known as the quintessential extrusion alloy, offers excellent surface finish after anodizing and outstanding extrudability. The 6061 provides greater mechanical strength, making it the preferred choice for structural and engineering applications. We also manufacture 1xxx series alloys for electrical applications where conductivity is the priority, as well as custom compositions for specific customer requirements.

The chemical composition of our bars is verified multiple times during melting and at the time of pouring, using our Thermo Scientific ARL 3460 optical emission spectrometer calibrated with certified reference standards. This rigorous control ensures each bar meets the alloy ranges agreed upon with the customer, which is fundamental for the extruder to obtain profiles with the expected mechanical properties, surface finish, and heat treatment response.

Our 7-inch diameter bars are compatible with the most common extrusion presses in Mexican industry. The 3.7-meter length is optimized to maximize press productivity, allowing the extrusion of multiple profiles per bar before loading a new billet. The bar finish comes directly from the casting table, and the solidification structure is designed to ensure homogeneous metal flow during extrusion.

Transformación Puebla serves aluminum profile extruders throughout Mexico, from the Bajio industrial corridor, where major extrusion plants are concentrated, to the Puebla metropolitan area, Mexico City, and the northern regions of the country. Our ISO 9001:2015 certification and over 35 years of experience in the aluminum alloy market back the reliability of our product and the consistency of our quality batch after batch.
