Medical grade tantalum is unalloyed and has a tendency to harden during processing and can be difficult to machine. Copper or soft aluminium would be good examples to compare it to 1,4 . Lubrication is therefore essential to avoiding the development of too much heat during tantalum machining, as tantalum may ignite at elevated temperatures.
