Lead alloys are often fabricated in extrusion and rolled forms to produce metal sheets, foil, traps, ribbons, wire, and other shapes. They are used for a variety of applications in the mechanical and electrical industries, including power transmission lines, automotive batteries, and motorized toys.
A lead tin alloy is typically used in the production of printed circuit boards (PCBs) as well as in the construction of power transmission and distribution equipment. In these cases, the alloy is often combined with other elements to improve strength or hardness.
The formula of a lead tin alloy is determined by the amount of antimony, tin, and other elements present. The alloy can be formulated in any combination of lead, tin and antimony in varying proportions for various purposes.
In the traditional type founding and hot metal typesetting systems, lead tin alloys are typically used in different proportions depending on the application. This is to produce a true and sharp cast, as well as to retain the correct dimensions and form after cooling down.
For these reasons, a lead tin alloy can be used in a wide range of types of casting and typesetting. For example, it is commonly used in individual character mechanical casting for hand setting, mechanical line casting, and stereo plate casting.
However, a lead tin alloy has to be heated in the right way in order to achieve its desired properties. In general, the harder the metal, the higher its melting point. This is especially important if the alloy is to be used in printing as it must be able to resist pressure during printing and not leave a mark on paper when sprayed with ink.
