High-integrity alloy profiles engineered for maximum energy absorption, structural stiffness, and multi-material vehicular bonding.
From internal combustion weight reduction to electric vehicle range extension, extruded aluminium alloy frameworks are redefining vehicular dynamics, passenger safety, and manufacturing efficiency.
Battery mass creates severe demands on structural efficiency. Utilizing 6xxx and 7xxx series extruded aluminium frames offsets battery payload by up to 40% compared to traditional mild steel, extending battery range and minimizing curb weight.
Aluminium multi-chamber hollow profiles deform progressively during impact. Specific energy absorption (kJ/kg) of properly aged 6082-T6 or 6005A alloys reaches up to twice that of standard steel, maximizing occupant survival cell safety.
Extrusion design flexibility permits continuous internal channels for liquid cooling circuits directly inside battery tray side members, unifying thermal management with structural chassis protection in a single profile.
Exploring how custom aluminium extrusion geometries are engineered for chassis, battery enclosures, and active safety structures.
Battery enclosures serve as the load-bearing spine of modern electric vehicles. Extruded aluminium multi-cavity perimeter beams, longitudinal ribs, and crossbars shield lithium-ion battery modules from side pole collisions and road debris intrusion.
By employing alloys like 6063-T6 and 6082-T6 with microstructural grain refinement, profiles deliver hermetic sealing capability, high yield strength (≥260 MPa), and frictionless integration with Friction Stir Welding (FSW) processing.
Automotive front and rear crash management systems require exceptional ductile behavior. Our custom 6xxx series extrusions are optimized for low-temperature toughness and controlled collapse without brittle cracking during standard 64 km/h offset impact tests.
Featuring variable wall thicknesses and internal shear webs, the extruded crash boxes convert kinetic crash energy into plastic deformation work, protecting the vehicle's cabin and powertrain components.
