Classification basis, material properties and applications of brass

Brass, a metal material widely used in industry and daily life, is widely used in various fields because of its good plasticity, wear resistance and corrosion resistance. According to different classification basis, brass can be divided into different types, including ordinary brass and special brass. These different types of brass have unique physical and chemical properties that make them great in different applications.

Basic classification of brass
According to alloy composition and performance characteristics, brass is divided into two categories: ordinary brass and special brass. Ordinary brass is a copper-zinc alloy with zinc as the main added element, while special brass is based on ordinary brass with other metal elements added, such as aluminum, nickel, tin, etc.

Material-based classification basis
1. Copper content and alloying elements
The copper content in brass and the types and contents of its alloying elements are the main factors that determine its properties and uses. According to the copper content, brass can be divided into high copper brass (such as H90, H80, etc.) and low copper brass (such as H65, H70, etc.). High-copper brass has higher strength, hardness and wear resistance, and is suitable for manufacturing high-strength, hardness and wear-resistant parts; while low-copper brass has better plasticity and corrosion resistance, and is suitable for manufacturing various Structural parts, springs, conductive parts, etc.
2. Addition of alloy elements
In addition to copper, other alloying elements added to brass are also important basis for classification. For example, adding aluminum can enhance the hardness and strength of brass, improve wear resistance, and is suitable for manufacturing high-strength, wear-resistant parts; adding nickel can improve the corrosion resistance and high-temperature performance of brass, and is suitable for manufacturing corrosion-resistant and high-temperature parts. Parts in the environment; adding tin can increase the hardness and strength of brass, improve wear resistance and corrosion resistance, and is suitable for manufacturing high-strength, wear-resistant and corrosion-resistant parts.

Application-based classification basis
1. Usage environment
The usage environment is an important basis for selecting brass models. For example, in a marine environment, you need to choose brass with good corrosion resistance; in a high temperature environment, you need to choose a brass with good high temperature performance; in an impact wear environment, you need to choose a brass with high strength and high hardness. .
2. Usage performance requirements
For occasions that require specific performance requirements, such as high strength, hardness, wear resistance or corrosion resistance, the corresponding brass model needs to be selected according to the performance requirements. For example, when manufacturing high-strength bolts, brass with high strength and hardness needs to be selected; when manufacturing submarine pipelines, brass with good corrosion resistance needs to be selected.
As an important metal material, brass is widely used in various fields because of its good mechanical properties, wear resistance and corrosion resistance. Brass can be divided into different types based on material properties and application requirements. The correct selection and use of different types of brass is critical to ensuring the quality and reliability of a variety of industrial and everyday products. By understanding the performance characteristics and application range of various types of brass, we can better select suitable materials to meet different application needs and manufacture brass bushings that meet the requirements.
