There is an unusual combination spacer and recoil buffer made of an alloy of brass, titanium and magnesium.
The hydride is a complex alloy of rare-earth elements and other metals that may be decomposed and reformed reversibly.
The precious metals could be extracted by stirring the molten alloy with molten lead: gold and silver dissolved in the lead while copper did not.
This new material, an alloy of titanium and nickel, has an ability to return to its original shape after bending.
The quality of the boxes themselves also suffered as material became scarce - a consignment of brass was lost with the Lusitania, and as brass was needed for the direct war effort, later boxes were of inferior alloy .

The luxury package also includes metallic paint, alloy wheels, a simple-to-operate cruise control, a trip computer and some very useful electric seats with memory.
The tests involved mixing the constituent elements of the alloy , heating and melting the mixture, and allowing it to cool and solidify.
