Annealing, quenching and heat treatment of bronze
Electrovek-Steel offers heat treatment technology for various bronze alloys. The supplier provides qualified information support, selects and optimizes all parameters of the heat treatment process.
Bronze is a multiphase system, so the choice of the quenching regime for bronze alloys is determined by their microstructure. To increase strength and hardness, bronze alloys prone to aging are most suitable, when the solubility of secondary phases in solid solutions increases during heating. Beryllium bronzes belong to such alloys. When quenching such alloys, the metal rapidly undergoes aging without polymorphic transformations (aluminum bronzes are an exception). To remove the internal stresses in the blanks and finished products after tempering, they spend their holidays. It is also possible subsequent thermomechanical processing (deformation at the temperature of polymorphic transformations).
Typical temperatures of quenching of bronze are heating up to 830… 850 0 С, with the subsequent aging at 350… 450 0 С.

To obtain a more equilibrium structure after mechanical or plastic treatment of bronze, annealing is most often used for the alloys in question. It can be ordinary (without phase transformations), homogenizing and recrystallizing. For ordinary annealing, the presence of low temperatures of metal heating (up to 250… 300 0 С) is typical, in which internal stresses are removed in a part or semifinished product. More often bronzes are subjected to recrystallization annealing, the temperature of which, depending on the grade of the alloy, is 650… 750 0 С. After such annealing, the structure of bronze becomes finely dispersed.
The choice of the temperature interval depends also on which group of bros — the deformed or foundry — belongs to the alloy. For foundry bronzes, the annealing and quenching temperatures are always 80… 150 0 С lower than for deformable ones.
The company Electrovek-steel offers to buy at a favorable price of the manufacturer forging, casting or rolling of various bronze alloys after their softening annealing. The supplier guarantees prompt delivery of products to the point specified by the consumer.
