What is H96 brass?
As a type of brass alloy, the naming of H96 indicates its core characteristic: its copper content is as high as 96%. The remaining components primarily consist of zinc. This alloy composition allows H96 brass to retain the excellent electrical and thermal conductivity of copper while enhancing its structural strength and durability through the addition of zinc.
H96 brass Physical Properties
H96 brass exhibits outstanding plasticity and corrosion resistance, with moderate hardness that facilitates various forming processes. Its tensile and yield strengths are excellent, meaning it can withstand significant external impact without deformation. At the same time, its good electrical and thermal conductivity make it irreplaceable in the electronics and electrical industries.
Comparison with copper
Compared to copper, which is almost pure copper, H96 brass benefits from the addition of zinc, resulting in improved hardness and wear resistance. Although copper outperforms in terms of electrical and thermal conductivity and possesses excellent ductility, its relatively lower structural strength limits its application in load-bearing structures. H96 brass demonstrates greater adaptability in this regard.
H96 brass Applications
Thanks to its outstanding physical properties and ease of processing, H96 brass is widely used in the construction industry for manufacturing door and window frames, water pipes, and other components. In the automotive industry, it serves as an ideal material for numerous parts and accessories. In the electrical industry, H96 brass is particularly valued for its excellent conductivity and is used in the production of wires and cables.
In summary, as a high-performance alloy material, H96 brass has become an indispensable resource in modern industry due to its balanced physical properties and broad applicability across various sectors.
FAQ
| Q: What exactly is H96 material? A: H96 is a copper-zinc alloy (brass) with a nominal composition of 96% copper and 4% zinc. It is known as Gilding Metal 96% or by its UNS number C21000. It is the brass grade with the highest copper content and lowest zinc content. |
| Q: What are the key properties of H96 (C21000) brass? A: Its key properties are: Excellent thermal and electrical conductivity (the highest among common brasses). Very good corrosion resistance (close to pure copper). Good ductility and formability for both cold and hot working. Characteristic reddish-gold color, making it aesthetically pleasing. |
| Q: How does H96 differ from pure copper (like T2/C11000)? A: While very close to pure copper, the small addition of zinc (4%) in H96 provides slightly higher strength, hardness, and wear resistance than pure copper, while retaining most of its conductivity and corrosion resistance. It is often a more cost-effective and durable alternative for many applications. |
| Q: What are the most common applications for H96 brass? A: Common applications include: Waveguides, heat exchanger/condenser tubes, heat sinks, electrical conductivity springs, jewelry, medals, commemorative coins, decorative architectural trim, and nameplates. |
| Q: Can H96 brass be welded or soldered? A: Yes, it has excellent solderability and brazability. However, welding can be challenging due to its high thermal conductivity and zinc content, which can lead to porosity and zinc fume. Specialized techniques (like TIG welding with proper filler metal) are required. |
| Q: What are the main standards that cover H96/C21000? A: It is covered by various international standards: China: GB/T 5231 (H96) USA: ASTM B36 (C21000 for sheet/plate/strip), ASTM B134 (C21000 for wire) Europe: EN CW500L (similar composition) Japan: JIS C2100 |
| Q: Is H96 brass resistant to dezincification? A: Yes, it has very high resistance to dezincification due to its high copper content (above 85%). This makes it suitable for use in certain aqueous environments where lower-copper brasses (like H70, H62) would be susceptible. |
| Q: What is the typical form and size range for H96 products? A: It is commonly supplied as strip/coil, sheet/plate, wire, and tube. Typical dimensions include: Strip/Coil: Thickness 0.1mm - 3.0mm, Width up to 600mm. Wire: Diameter 0.5mm - 12.0mm. Tube: Outer Diameter (OD) 3mm - 50mm. |
