The ‘Standard Specifications’ series define the standard specifications for custom orders. They correspond to the needs of the majority of the precious metals industry in North America and illustrate most of Umicore’s production capabilities. Should you, however, have a request that seems to fall outside of what is published here, then please don’t hesitate to contact us for further assistance. Umicore updates its ‘Standard Specifications’ regularly based on customer feedback, market trends and technological developments.

For each product the ‘Standard Specifications’ show:

  • Product name and description

  • Available materials for these products
  • Standard production capabilities and tolerances
  • Temper
  • Standard packaging

In order to speed up the processing of product inquiries and orders we encourage you to use the terminology used in the ‘Standard Specifications’ and to clearly indicate any requests that deviate from these ‘Standard Specifications’, such as tighter specifications.

Throughout the ‘Standard Specification’ series all dimensions are provided in mm and temperatures in °C. Conversions to inches, feet and °F are for reference only.
