Tin is also used to reduce coefficient of friction for bearing applications. Lead alloys are castable by most methods. Intricate details can be reproduced, and the surface can be readily painted. Lead alloys can be extruded into pipes, bars, channels, and rods. Cold-rolled lead sheet is available in thicknesses ranging from foil to 2 in., in widths to 11 ft, and in lengths to 60 ft.
Lead often requires support by other materials.
Other clad combinations are produced by spot welding, spraying, hot dipping, and electroplating. These laminates are particularly useful in noise and vibration-absorption applications.
