Niobium Sheet, 152.4mm x 6", Soft Gauge:30 ga. (0.25mm) it also shows each sizeThis soft niobium sheet offers the benefit of having fabrication metal on hand when you need it; custom cut it to the exact size and shape your design requires. Soft sheet is easy to bend, shape and hammer; it is an ideal starting point for forming, shaping and wrapping. Keep in mind that hardness is changeable (by annealing or heat hardening) and is relative among metal types (each temper will feel and handle differently from one metal to another).
