Pb, Sn Ab ALLOYS
The alloys are used because of their mechanical properties in mechanical engineering and in printing.
Bearing metals made of lead and tin
Usage: bearing shells and liners of high-speed engines, mills, turbines, rolling mills, compressors, wagons, cars and sliding surfaces of various mechanical components.

Type alloys
Type alloys are alloys of lead, tin and antimony. They are used printing-offices for casting of letters, lines, composing materials and stereotypes. Due to their excellent casting quality they are also used for casting of very small products. Type alloys are delivered in ingots or needles. Shape of ingots make splitting very easy during dosing. The needles have a hole on one side to be hinged in batching device.
