Designation and Standards
Standard Designation: H96 (Common Brass)
Corresponding International Standards: GB/T 5231-2001, GB/T 1527-1997
Material Category: Copper-Zinc Alloy (Cu-Zn), Copper Content 95%-97%
Product Features
High Electrical and Thermal Conductivity: Conductivity close to pure copper (about 90% IACS), suitable for electronic and electrical applications.
Excellent Corrosion Resistance: Strong corrosion resistance in atmospheric and freshwater environments, with no tendency for stress corrosion cracking.
Good Processability: Easy to cold/hot press, supports welding, forging, tin plating, and other processes.
Moderate Strength: The lowest strength among common brass, but higher than pure copper, with tensile strength ≥205-320 MPa.

FAQ
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.
