Properties of H96 Brass

The main chemical components of H96 brass are copper and zinc. The copper content is typically 95% to 97%,

while zinc, as the main alloying element, determines the mechanical properties and corrosion resistance of the brass.

In addition to copper and zinc, H96 brass also contains small amounts of lead, iron, phosphorus, and other elements.

These components play an important role in the material's machinability, corrosion resistance, and resistance to stress corrosion cracking.

Its specific chemical composition is as follows:

Copper (Cu): 95.0% ~ 97.0%
Zinc (Zn): Balance
Lead (Pb): ≤0.03%
Phosphorus (P): ≤0.01%
Iron (Fe): ≤0.10%
Antimony (Sb): ≤0.005%
Bismuth (Bi): ≤0.002%
Total impurities: ≤0.2%
This combination of chemical components ensures that H96 brass possesses both high strength and good electrical and thermal conductivity, as well as corrosion resistance suitable for various environments.

H96 brass exhibits good mechanical properties, with a tensile strength exceeding 205 MPa,

and an elongation greater than 10%, indicating good toughness and ductility.

This allows H96 brass to withstand significant tensile forces during processing,

and provides good formability. Its mechanical properties are as follows:

Tensile strength (σb): ≥205 MPa

Elongation (δ10): ≥10%

These properties make H96 brass suitable not only for various cold and hot working processes,

but also ensure the dimensional and shape stability of parts during processing, making it particularly suitable for mass production of parts.

The heat treatment process for H96 brass mainly includes hot working and annealing. The hot working temperature range is 775℃ to 850℃,

and the annealing temperature is 540℃ to 600℃. Annealing effectively eliminates internal stress generated during processing,improves the material's plasticity and ductility, thereby enhancing its adaptability and processing performance.

A low-temperature annealing temperature of 200℃ helps relieve stress and improve the material's mechanical properties,resulting in better durability in different working environments.

Electronics & Electrical: Conductive terminals, heat sinks, relay components.

Industrial Manufacturing: Cold heading parts, rivets, welded structural parts.

Q: What is the difference between H96 and red copper (pure copper)?

A: H96 is a copper-zinc alloy (brass) with higher strength but slightly lower conductivity. Red copper is pure copper (Cu≥99.9%) with superior conductivity but lower strength.

Q: What is the color of H96 brass?

A: It has a light yellow color due to the high copper content, which is distinctly different from the reddish-purple color of red copper.

Q: Is it suitable for seawater environments?

A: Tin is needed (e.g., naval brass) for seawater corrosion resistance. H96 is recommended for freshwater environments.
