Precious Metal Semifinished

Heraeus supplies precious metal demi-products in a great variety of alloy compositions, dimentions and shapes. Let us know your application criteria and we will be pleased to advise you in choosing the appropriate material. We produce rods with diameters from 60 mm to 1 mm and wires with diameters from 4 mm to 0.001 mm. Platinum wires with a diameter less than 0.01 mm are manufactured by the Wollaston process (i.e. drawn in a silver sleeve). The protective sleeve is etched off immediately prior to use by the customer. We produce the diameters and lengths individually to meet your requirements.
