Are you interested in heat treatment: annealing, hardening of rolled copper? Supplier Evek GmbH offers to buy heat-treated copper at an affordable price in a wide range. We provide delivery of products anywhere in the continent. The price is optimal.

Types of heat treated copper

To change the mechanical characteristics of rolled copper, quenching and annealing are used. The first is used to increase strength, and the second - to reduce internal stresses that arise during, for example, cold deformation, welding or power turning copper billets.

Quenching

Tempering temperature of copper products is 580...630°C, with soaking at these temperatures and subsequent cooling in calm air. As a result, the hardness of copper products increases and their elastic properties increase.

Two-step annealing

To obtain a stress-free equilibrium structure, the semi-finished products are annealed in two stages. During the first stage the products are heated to quenching temperatures, after which they are slowly cooled and heated again from 350...400°С. The cooling of the final product is performed twice as slowly, which facilitates the removal of technological stresses and obtaining a more homogeneous metal structure.

Descaling

Heat treatment of rolled copper products is also used for descaling - the billets are heated to 450 ... 500°C and quickly cooled. Supplier Evek GmbH offers to buy heat treated copper of domestic and foreign production at fair price in wide assortment. We provide delivery of products anywhere in the continent. The price is optimal.

Furnaces

In view of relatively low heating temperatures during heat treatment of copper bars the furnace with controlled atmosphere or electric furnace is used mainly. In the case of significant volumes of production thermal furnaces are equipped with means of mechanization of feeding and delivery of metal from the working area of the furnace, and for small volumes - chamber or even muffle resistance electric furnaces.

Oxidation-free atmosphere

Oxidation-free atmosphere in flame furnaces for thermal treatment of copper is created by reducing the amount of oxygen in the furnace atmosphere. Less often used nitrogen as in some alloys, it forms nitrides, which increases the hardness and reduces the ductility of copper products. From this point of view, undesirable heating of copper in a nitrogen-containing atmosphere in the temperature range of 250 ... 280 ° C, when nitro is particularly intense.
