In this article, published in Stainless Steel World News – December 2018, the role of Ferralium in the refurbishment of the Statue of Liberty is explored.

Constructed in 1886, this iconic structure was suffering badly with galvanic corrosion some 90 years later. The combination of different materials within the statue created almost perfect conditions for accelerated corrosion. Therefore, an extensive refurbishment process was first mooted in the 1970’s. Following a lengthy review of suitable materials, Ferralium was selected as the most suitable material for the supporting bars, on to which the outer copper form was mounted. Having a similar thermal expansion coefficient and elasticity with other wrought iron components previously installed was helpful, along with minimal reaction to the copper cladding. However, the significantly greater strength and ability to supply as bars and bolts meant that it could be used throughout the refurbishment project.
