Johnson Matthey produces a wide range of round materials of many different sizes. They range from simple rods up to fine wires and capillary tubes.
The standard diameter for wire starts from 100 µm, although depending on the material, significant quantities of 50 µm can also be produced. For tubes these values are an outer diameter of 0.8 and an inner diameter of 0.5 mm.

In addition to the pure metals, we offer various alloys made of iridium/platinum and rhodium/platinum, as well as silver/copper or silver/nickel and silver/palladium.
All the above mentioned materials are available as rods. Silver is also offered as a rod material with a diameter of up to 60mm. On request we can offer additional alloys. Should you require other dimensions we will gladly verify our delivery possibilities.
