Argentina Automotive Parts Aluminium Die Casting Market Size and Share - Growth Analysis Report and Forecast Trends 2026-2030

Aluminium die casting is a core forming process for high-volume automotive components such as gearbox housings, engine blocks, oil pans, suspension parts and increasingly battery-related structural pieces. In Argentina, the sector supplies both domestic vehicle assembly plants and aftermarket channels, while a meaningful share of output is exported through regional OEMs. The market's roughly 11.6% annual expansion reflects a recovery from a depressed 2023-2024 base and structural shifts toward lighter powertrain and chassis components.

• •Market size estimated at USD 0.39 billion in 2025
• •Annual growth rate of approximately 11.6%
• •Demand concentrated around transmission, engine, and emerging EV battery-housing components

Vehicle lightweighting to meet fuel-economy and emissions standards remains the primary structural driver, as aluminium replaces cast iron and stamped steel in transmission and engine sub-assemblies. A second driver is the slow but rising penetration of electrified and hybrid vehicles across Argentina and the broader MERCOSUR region, which requires die-cast aluminium battery enclosures, motor housings and power-electronics casings. Third, exchange-rate volatility and import-restriction regimes have incentivised local content in aluminium components, supporting domestic die-casters.

• •Lightweighting mandates accelerating substitution of iron with aluminium castings
• •EV and hybrid adoption creating demand for battery enclosures and motor housings
• •Local-content rules and import controls favouring domestic aluminium die-cast output

By process, high-pressure die casting dominates volume for transmission and engine components, while gravity and low-pressure casting remain relevant for larger structural parts. By application, powertrain and chassis sub-assemblies account for the majority of revenue, with body-and-structure die-castings growing fastest on the back of new SUV and pickup programmes from regional OEMs. Geographically, Buenos Aires province - home to most terminal assembly plants - concentrates demand, with Córdoba and Santa Fe contributing meaningful tier-supplier capacity and exports.

• •Powertrain applications lead revenue share; structural parts growing fastest
• •High-pressure die casting is the dominant process
• •Demand centred in Buenos Aires, with manufacturing footprint also in Córdoba and Santa Fe

What are the recent trends and outlook?

Through the latter half of the decade, the market is expected to benefit from a normalised domestic production environment and incremental electrification under Argentina's EV regulatory framework. Suppliers are investing in larger-tonnage high-pressure machines and in-house heat treatment to win structural and battery-housing programmes from global OEMs sourcing from Argentina. Commodity volatility in primary aluminium and US trade measures on aluminium imports remain the principal downside risks for input costs and export pricing.

• •Capex shifting toward large-tonnage presses and heat-treatment capacity for structural castings
• •Battery-housing and motor-housing work emerging as a new revenue line for tier-one die-casters
• •Aluminium price volatility and trade measures on imports are key risks to margins
