Title: In-depth analysis of HPB9-2 lead brass wire, forgings, plates, round steel heat treatment process, chemical composition analysis and application fields.
1. Overview of HPB59-2 lead brass.
HPB59-2 lead brass is a kind of brass with lead as the main alloying element, which is widely used in the manufacture of various precision mechanical parts, electrical connectors, springs, etc. because of its excellent friction and wear resistance. Its main components include lead, copper, tin, aluminum, zinc and other elements, and by adjusting the content of these elements, lead brass with different properties can be obtained.
2. Heat treatment process.
Heat treatment is a key process to improve the mechanical properties of lead brass. According to the different requirements of the product, annealing, solution treatment, aging and other heat treatment processes can be used.
1.Annealing: The lead brass is heated to a certain temperature, held for a certain time, and then cooled slowly to eliminate internal stress and improve plasticity and toughness.
2.Solution treatment: The lead brass is heated to a high temperature to fully dissolve the alloying elements to improve the strength and hardness. It is then cooled rapidly to keep the solid solution stable.
3.Aging: After solution treatment, lead brass will precipitate at room temperature or under heating to form a stable phase, which further improves the strength and hardness.
3. Chemical composition analysis.
The chemical composition of HPB59-2 lead brass mainly includes lead, copper, tin, aluminum, zinc and other elements. Among them, the content of lead has a significant effect on the friction reduction and wear resistance of lead brass. Copper is the matrix element that determines the electrical conductivity, thermal conductivity and plasticity of lead brass; Elements such as tin, aluminum, zinc, etc., can improve the strength and hardness of lead brass.
Fourth, the field of application.
