Chemical Composition of H96 Brass

H96 ordinary brass is a widely used copper alloy with high strength, good electrical and thermal conductivity, excellent corrosion resistance, and good ductility. It is mainly composed of copper and zinc and is a typical brass material. Due to its excellent comprehensive properties, H96 ordinary brass has important applications in many industries.

The chemical composition of H96 ordinary brass is mainly composed of copper and zinc. The high copper content ensures its good electrical and thermal conductivity. The specific chemical composition is as follows:
Copper (Cu): 95.0%~97.0%. Copper is the main component of H96 brass, determining the alloy's electrical and thermal conductivity and strong corrosion resistance. The high copper content ensures the material's stability and durability.

Zinc (Zn): Balance. Zinc is another important component of H96 brass, playing a role in improving ductility and corrosion resistance. Although the zinc content is not fixed, it usually occupies the balance, giving the brass good machinability and strength.

Lead (Pb): ≤0.03%. The lead content is strictly controlled at low levels to ensure the material's environmental friendliness and prevent adverse health effects during use.

Phosphorus (P): ≤0.01%. The phosphorus content is controlled at very low levels, which helps avoid the influence of phosphides on the copper alloy, maintaining its good plasticity and corrosion resistance.

Iron (Fe): ≤0.10%. The low iron content in H96 brass helps maintain the stability and toughness of the brass, avoiding the impact of iron on alloy properties.

Antimony (Sb): ≤0.005%. The antimony content is very low, having a small impact on brass, but it can sometimes improve the alloy's strength.

Bismuth (Bi): ≤0.002%. The bismuth content is also trace, having some influence on the alloy's hardness and plasticity, but it is not dominant.

Total Impurities: ≤0.2%. Strict control of impurity content ensures the high purity of H96 brass, thus guaranteeing its excellent physical properties.

Through a rational configuration of its chemical composition, H96 brass maintains its excellent performance characteristics, such as good strength, corrosion resistance, and good plasticity and machinability.

H96 ordinary brass exhibits good mechanical properties, especially in tensile strength and ductility. Its main mechanical properties are as follows:

Tensile Strength (σb): ≥205 MPa. Tensile strength is an indicator of a material's resistance to tension. H96 brass possesses a certain tensile strength, meeting the mechanical requirements of many applications.

Elongation (δ10): ≥10%. Elongation indicates a material's ability to undergo plastic deformation during tension. H96 brass has moderate elongation, indicating that it can undergo plastic deformation under certain forces, making it suitable for processing and forming.

These mechanical properties make H96 ordinary brass suitable for applications that do not require extremely high strength but have high requirements for plasticity and machinability. Its moderate tensile strength and good ductility give H96 brass excellent machinability during both cold and hot pressure processing.

The heat treatment specifications for H96 brass primarily affect its machinability and mechanical properties. Appropriate heat treatment can further optimize its mechanical properties, plasticity, and stability. The heat treatment specifications for H96 brass are as follows:
Hot working temperature: 775℃~850℃. Within this temperature range, H96 brass exhibits optimal plasticity and machinability, making it suitable for forging, cold stamping, and other processing operations.

Annealing temperature: 540℃~600℃. Annealing is a commonly used metal heat treatment method. Annealing can make the brass structure more uniform, eliminate internal stresses generated during processing, thereby improving its machinability and ductility.

These heat treatment specifications enable H96 brass to maintain good stability and improve its mechanical properties during various processing procedures.
