Custom Aluminum Alloy Ingots

Aluminum alloy ingots are the flagship product of Transformación Puebla, S.A. de C.V. and the preferred solution for foundries, automotive parts manufacturers, and metalworking companies throughout Mexico. Each ingot, weighing approximately 11 kilograms, is manufactured under strict quality controls at our San Pedro Cholula, Puebla plant, guaranteeing exact chemical composition verified by optical emission spectrometry.

Our manufacturing process begins with rigorous raw material selection and classification, which includes high-quality recovered aluminum and, when required by the customer, primary aluminum (P1020, P0610) for ultra-low iron trace alloys such as A356.2. The material is melted in our reverberatory, rotary, and tilting furnaces, then subjected to a complete metallurgical treatment that includes fluxing for oxide removal, rotary degassing with nitrogen to reduce porosity, and liquid metal filtration to trap non-metallic inclusions.

We offer an extensive catalog of standard alloys covering the families most in demand by Mexican industry: AlSi7 (A356/A356.2), ideal for high structural integrity automotive components; AlSi10 (A360), widely used in die-cast parts; AlSi11 (A383/ADC12), the preferred alloy for high-productivity die-casting; 380, the workhorse of North American automotive casting; and 413, renowned for its excellent fluidity and corrosion resistance. Additionally, we manufacture fully customized compositions by precisely adjusting levels of silicon, copper, magnesium, manganese, zinc, and other alloying elements to the buyer's exact specifications.

The chemical composition of each heat is verified multiple times during the melting and pouring process with our Thermo Scientific ARL 3460 spectrometer, a spark optical emission (spark-OES) instrument capable of simultaneously analyzing over 12 elements. This equipment is calibrated with certified reference standards, ensuring traceable and reliable measurements. If the composition does not meet the specified range, adjustments are made and the melt is re-analyzed until full compliance is achieved. Each batch is delivered with its chemical analysis certificate, and material radioactivity is independently measured in both raw materials and finished product.

Our aluminum ingots serve multiple industries across Mexico. In the automotive sector, which represents one of the strongest industrial vocations in the state of Puebla thanks to the VW/Audi cluster, our ingots are used for casting engine components, transmission housings, structural brackets, intake manifolds, and a wide variety of aluminum parts. In the electrical industry, we supply ingots for manufacturing conductors, bus bars, and connectors. For the steel industry, we offer ingots with specific compositions for deoxidation processes and aluminum additions in steel furnaces.

Transformación Puebla holds ISO 9001:2015 certification and has an installed capacity of 4,000 metric tons per year, allowing us to fulfill both spot orders and continuous supply contracts with flexible delivery schedules. Our plant in San Pedro Cholula is strategically located to serve the country's main industrial hubs, including the Puebla-Tlaxcala automotive corridor, the Queretaro and Bajio industrial zone, the Mexico City metropolitan area, and northern Mexico.
