XTRAL 728®

A GENERATION AHEAD

XTRAL 728®

A generation ahead

The new ADR regulations havereinforced the safety standards thatapply to the transport of dangerousproducts thereby strengthening theposition occupied by aluminium, ametal that already offers significantadvantages. The intrinsic qualities ofAlcan's XTral 728® in fact exceed therequirements. XTral 728® is specifically intended to buildtankers used to transport dangerousmaterials safely. Its outstandingformability is the guarantee that itwill withstand impact and ensuresafety. XTral 728® is the fruit of Alcan's ability to innovate and itsperfect mastery of the technologyneeded to design and produce thenew alloy.

Technologicalinnovationand safetyAlcan created and developed XTral 728® at its research centre inclose consultation with industrialvehicle manufacturers and specialistswith whom it has enjoyed arelationship based on trust for severaldecades.

XTral 728® is a totally recyclable alloy.Its lighter weight and resulting energysavings mean that XTral 728®complies with the demands ofsustainable development.

Tighter tolerancesTighter tolerances facilitate easierwelding, processing and optimise theweight reduction.

Improved weldabilityFacilitates assembly of weldedtankers.

Improved resistance to corrosionThe increased resistance to corrosion of XTral 728® combined with correct use results in excellent life in service.

High surface qualityXTral 728® presents high surfacequality in terms of:• hygiene: it is simple to clean

the inside of the tankers,• appearance: even when used without

an additional coating it has anattractive exterior.

Easier formingForming is made easier by the metal'sexcellent formability and bendability.Safety is reinforced by its capacity toabsorb energy in the event of impact.

A variety of precutshapesOur Associated Services are full andvaried and can provide a range ofpre-cut shapes for tanker shells, endplates, etc.

While it complies totally with the new and more demanding ADR regulations, XTral 728® permits the use of aluminium down to a thickness of 5 mm.The weight of the tanker is thereforemuch less and enables the carryingcapacity to be increased significantlythereby considerably reducing thefuel consumption.In the end downgaging results in lessmaterial beeing used, more productstransported and less fuel is consumedresulting in higher profits for all theoperators in the sector concerned.
