H59 brass, a member of the brass alloy family, is known for its impressive combination of mechanical properties, corrosion resistance, and workability. H59 brass is the cheapest brass. It has high strength, hardness and good plasticity. It can still withstand pressure processing well in the hot state.
Chemical Composition of H59 Brass
H59 brass is primarily composed of copper (Cu) and zinc (Zn), with trace amounts of other elements that contribute to its unique properties. The key components of H59 brass typically include:
- Copper (Cu): Copper is the primary base metal in H59 brass, comprising the majority of its composition, typically around 59% to 62%. Copper provides the alloy with its inherent malleability and excellent electrical conductivity.
- Zinc (Zn): Zinc is the primary alloying element in H59 brass, typically accounting for about 38% to 40% of the composition. Zinc enhances the hardness and strength of the alloy while influencing its corrosion resistance.
- Other Trace Elements: H59 brass may contain trace elements like lead (Pb), iron (Fe), and tin (Sn) in minimal amounts, depending on the specific manufacturing process. These trace elements can slightly affect the alloy’s properties.
Mechanical Properties of H59 Brass
- Tensile Strength: H59 brass has a tensile strength ranging from 315 to 350 megapascals (MPa), depending on the manufacturing process.
- Yield Strength: The yield strength of H59 brass typically falls in the range of 200 to 250 MPa.
- Elongation: H59 brass boasts good elongation properties, with values ranging from 35% to 45%.
- Hardness: H59 brass has a Rockwell hardness (HRB) of approximately 60 to 80, depending on the tempering process.
Common Applications of H59 Brass
- Plumbing and Fittings: H59 brass is commonly used in plumbing fixtures, valves, and fittings due to its excellent corrosion resistance and ability to withstand high water pressures.
- Electrical Connectors: Its high electrical conductivity makes H59 brass suitable for electrical connectors machining and terminals.
- Decorative Items: The attractive golden color of H59 brass, along with its ease of brass cnc machining, makes it a popular choice for decorative items, including jewelry, ornaments, and architectural details.
- Musical Instruments: Brass instruments, such as trumpets and saxophones, often use H59 brass for its acoustical properties and durability.
- Marine Hardware: H59 brass is preferred in marine environments due to its corrosion resistance, making it suitable for marine hardware and components.
- Automotive Parts: It is used in various automotive components, including radiator cores and hose fittings.
