AMAG EURAL

6026LF

According to EU directives: 2000/53/EU (ELV) – 2011/65/EU (RoHS II)

Presentation

This innovative alloy has been conceived and developed in Eural Gnutti SpA’s research laboratories, in order to meet the most recent standards for the protection of the environment, removing lead. It is particularly suitable for being machined on high speed automatic lathes. It has good resistance to corrosion, medium-high mechanical properties, good suitability for decorative and industrial hard anodizing. It is also used for hot forging purposes.

Eural 6026LF alloy does not contain tin (Sn) which, as it has been proved, causes weakness and cracking of the machined parts when submitted to stress and high temperature.

Due to its brittle nature, tin has the dangerous tendency to suddenly break without signifi cant previous deformation (strain).

It can replace 2007, 2011, 2015, 2028, 2030, 2044, 6012, 6012A, 6020, 6021, 6023, 6028, 6033, 6040, 6041, 6042, 6061, 6065, 6082, 6262, 6064A, 6262A, 6351, 7020 alloys.

Main applications

automotive industry, electric and electronic industry, hot forging, screws, bolts, nuts, threaded parts.
