aluminium ec rods


Our Aluminium EC (Electrical Conductor) Grade Rods are one of the preferred types in electrical industries. Owing to excellent characteristics of our aluminium, they are predominantly used in overhead power transmission and distribution cables.

With purity of 99.5% aluminium (minimum), our Aluminium EC Grade Rod is the preferred choice and alternative to copper due to its high conductivity, lightweight characteristic, excellent form, corrosion resistance and superb malleability to fit a wide range of processing.

A detailed specification of our Aluminium EC Grade Rod is as follows:

EC 1350

EC 1370

Widely used for electrical conductor as wire and solid shaped conductor

Widely used in the production of electrical conductor for magnetic motor

With it's purity of 99.7% of aluminium (higher than others), makes this conductor has higher conductivity with softer rod

ConductivityIn excess of twice that of copper by unit weight

Light WeightDue to its proven light weight and excellent bend qualities make our EC Aluminium favorable for further customization

WorkabilityPermitting a wide range of processing from wire drawing to extrusion or rolling. Excellent bend quality. Aluinium possesses high elongation that eases the cold work process

Corrosion ResistanceA tough, protective oxide coating quickly forms on freshly exposed aluminium and it does not thicken significantly from continued exposure to air

CreepLike all metal under sustained stress, there is a gradual deformation over a term of years. With aluminium, design factors take it into account

Compatibility with InsulationDoes not adhere to or combine with usual insulating materials. No tin-coating required; clean stripping
