Relevance of heat treatment of tin alloys

Heat treatment as a means of strengthening tin alloys is not applicable, because this metal has a low melting point. However, a kind of "annealing" can be called the placement of tin blanks in an environment with a constant temperature of 30 ... 35 ° C. Under such temperature conditions, accelerated aging of tin occurs, which is useful for filamentous deposition of its crystals on the surface of other metals, in particular copper.

How is tin heat treated?

The initial metal is cleaned from foreign impurities, non-metallic inclusions, oxide films, etc.; the blanks are heated to a temperature of 120...140°С, thus the growth rate of whisker crystals is increased. Once the desired coating thickness has been reached, the billet is removed from the furnace, cooled in still air and then heated again, but to a temperature of 150 °C. The purpose of this finish heat treatment is the formation of stable intermetallic compounds of copper and tin. The supplier Evek GmbH offers to buy a wide range of tin at an affordable price.

Heat treatment of tin plates surface

This type of heat treatment of tin is used to intensify diffusion processes. This type of heat treatment is particularly beneficial for copper alloys such as brass and bronze, which are covered with a thin layer of tin. As a result of heating to temperatures of 140 ... 150 ° C, followed by cooling together with the furnace occurs:

• The removal of internal stresses in the alloys, for example, after their plastic deformation;
• Stabilization of the dimensions of the finished parts;
• Wetting the surface of the alloy, which facilitates soldering.
