PGM Platinum

Platinum is used in a wide variety of applications with platinum jewellery accounting for almost a quarter of annual platinum demand, but the largest use is in automotive catalytic converters..

PGM Palladium

Palladium, although having the lowest melting point and being the least dense of all the PGMs, finds its way into many crucial applications. Whilst mainly used in catalytic converters, it is also an important catalyst for chemical markets. When combined with silver, palladium alloys are also used in medical, military and aerospace applications. In plating applications, it is often alloyed with nickel and gold to offer an excellent combination of conductivity, corrosion resistance and hardness.
