Annealing, quenching and heat treatment of tin
Buy tin, both in pure form and in alloys with other metals, at competitive prices manufacturer, the company offers Electrocentury-steel. Supplier ensures timely delivery to any destination specified by the customer.
Where used, the heat treatment of tin
Heat treatment as a means of hardening alloys of tin are not applicable, because the metal has a low melting point. However, a kind of «annealing» can be called the room of tin billets in an environment with a constant temperature of 30…350 C. At such temperatures is accelerated aging of tin, useful for a filamentary deposition of its crystals on the surface of other metals, particularly copper.
The process of heat treatment the tin is the following:
- The metal is cleaned of extraneous dirt, non-metallic inclusions, oxide films, etc.;
- The workpieces are heated to a temperature of 120…1400 C, causing the rate of formation of whiskers increases;
- Upon reaching the desired coating thickness, the workpiece is removed from the furnace, cooled in calm air and then again heated but to a temperature of 1500 C. the Purpose of this finishing heat treatment — education-resistant intermetallic compounds of copper and tin.
Clad thus, the leaves are used to improve the soldering copper parts.
The company Electrocentury-steel offers to purchase affordable tin of pellets. The supplier provides timely delivery of goods to the point specified by the user.
Heat treatment of the surface of tin sheets
This type of thermal exposure of the tin used for the intensification of diffusion processes. Particularly beneficial this kind of heat treatment effect on copper alloys — brass and bronze, which are covered with a thin layer of tin. As a result of heating to temperatures of 140…1500 C, With subsequent cooling with the oven happens:
- The removal of internal stresses in the alloy, for example, after their plastic deformation;
- Stabilization of the sizes of the finished parts;
- Wetting the surface of the alloy, making it easier to solder.
To buy a variety of wire rod and semi-finished products of tin at affordable prices manufacturers company offers Electrocentury-steel. The supplier guarantees the timely transportation of products to the address set by the customer.
