Lead-based white metals are formed by a soft lead matrix reinforced with antimony and copper. Nowadays, these alloys are less common due to the restrictions on the use of lead. Nevertheless, they are cheaper than tin-based white metals, and depending on the content of antimony and tin you can find a wide variety of compositions on the market. We manufacture white metals under international standars, but also under customers’ own specifications. All compositions can be supplied  in different formats: ingot, billet and wire.
