Blanks in Aluminum and Stainless Steel/Inox
These materials are a good alternative to base metal or even to plated metal blanks for the low value denominations.
This material has a good standard corrosion resistance by itself without surface treatment. Furthermore the weight is about 1/3 of copper based alloys.
Aluminum blanks supplied by RBI are slightly lubricated and therefore strike ready and very easy to mint.
Our sophisticated cutting and handling technology reduces damages on the blanks surface.
Stainless steel is heavier than aluminum, which gives a more valuable feeling. The material has a good corrosion resistance without surface treatment, a shiny surface and at low cost.
