Oricalco - thermal shape memory fabric
The first orthogonal weaving example of Nitinol. The 'Thermal Shape Memory Alloy' is characterized by its extraordinary ability to recover any shape, pre-programmed, upon heating. Until today this light weight alloy with about 50% Titanium inside has been used in advanced sectors like space and recently in medical applications. Moreover this fabric is the first for which the shape memory alloy, named Nitinol, was weaved orthogonally that is to say that Oricalco is the first fabric with shape mem
