The company, unlike the rival [[OMAS]], suffered heavy damage from bombing, the plants were destroyed in [[1945]] and raw materials and archives were lost. But despite this after the war there was a great effort to rebuild the business. In [[1947]], following the new market trends dictated by the [[Parker 51]], [[Aurora]] introduced an [[hooded nib]] model. The design of the pen was entrusted to the architect [http://it.wikipedia.org/wiki/Marcello_Nizzoli Marcello Nizzoli]: the [[Aurora 88|88]] was a masterpiece of the [[Aurora]] production, and obtained a great success.  

L'azienda, al contrario della concorrente [[OMAS]], subì pesanti danni dai bombardamenti, nel [[1945]] gli impianti della sede di Via Basilica vennero distrutti da un incendio e le materie prime e gli archivi vennero persi, ma nonostante questo fu un grande sforzo per ricostruire le attività dagli stabilimenti di Strada dell'Abbazia di Stura, dove ancora oggi si trova l'azienda. Alla fine del [[1946]], seguendo di nuovo le tendenze del mercato dettate dall'introduzione del modello [[Parker 51|51]] della [[Parker]] anche l'[[Aurora]] introdusse un modello a pennino coperto. Affidata al design dell'architetto industriale [http://it.wikipedia.org/wiki/Marcello_Nizzoli Marcello Nizzoli], la [[Aurora 88|88]] è uno dei capolavori della produzione dell'azienda ed ebbe un enorme successo.  

The [[Aurora 88|88]] model was equipped with a very advanced [[piston filler]], with differential threads. The pen was made with a metal cap in both gold-plated metal or using an alloy of nickel and silver called ''[[Nikargenta]]''. The body was in celluloid with a transparent section, while the handle of the piston was in hard rubber. The [[Aurora 88|88]] was qualitatively and technologically far more advanced than a [[Parker 51|51]], the only plastic part was the sheath of the nib, and the feeder had a sophisticated supply system which allowed a regular ink flux.

In [[1957]] (or 1954), to counter the massive advent of the ballpoint pens, [[Aurora]] launched the [[Duo-Cart]], a [[cartridge filler]] economic model. The cartridges were carried out in polyethylene, and designed by [http://it.wikipedia.org/wiki/Giulio_Natta Giulio Natta], Nobel prize for chemistry. The distinguishing characteristic of the pen, exposed by the name, was the ability to contain within its barrel a second cartridge, to avoid to get out of ink. Following the same design the [[Aurora 888|888]] was also introduced, a [[cartridge filler]] version of the [[Aurora 88|88]].

In the following years the advent of the ballpoint pen affected the production in a ever more massive way. The company was sold to the family Verona in the early '60s, but always remained active in the market, starting to produce ballpoint pens. In [[1963]] was introduced the [[Aurora 98|98]] model, still a [[piston filler]] equipped with an additional reserve of ink called ''[[Riserva Magica]]'' which allowed to obtain a few drops of ink when the tank was empty. In [[1965]] the economic line [[Auretta]] was introduced, a [[cartridge filler]] produced in colorful plastic and directed especially to students.
