Chemical Composition of H62 Brass
H62 brass, like other brass alloys, is primarily composed of copper (Cu) and zinc (Zn), with trace elements that contribute to its unique characteristics. The key components of H62 brass typically include:
Copper (Cu): Copper is the predominant component in H62 brass, typically accounting for about 61% to 63% of the alloy's composition. Copper provides the alloy with its inherent electrical conductivity, malleability, and corrosion resistance.
Zinc (Zn): Zinc is the primary alloying element in H62 brass, usually making up approximately 36% to 38% of the composition. Zinc enhances the hardness and strength of the alloy while influencing its corrosion resistance.
Trace Elements: H62 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 but are typically present in very low concentrations.

Corrosion Resistance and Durability
Corrosion resistance is a notable feature of H62 brass, primarily due to the presence of zinc in the alloy. Similar to H59 brass, H62 brass forms a protective oxide layer on its surface, which acts as a barrier against further corrosion. This property makes it highly resistant to atmospheric corrosion, ensuring a long service life even in outdoor and marine environments.
H62 brass's durability extends to its resistance to dezincification, making it a reliable choice for applications where exposure to water and moist conditions is a concern. This resistance ensures that the alloy maintains its structural integrity over time.
H59 vs H62 Brass, Which One to Choose - Difference Between H59 and H62
H59 brass has cheap price and ordinary corrosion resistance, so it is generally used for machine parts, welding parts, hot stamping and hot rolling parts, suitable for electrical appliances, electronics, lighting, hardware, mounting horizontal, switch, gasket, battery contact piece, copper button, watch strap, decorative necklace, bracelet, ring and other brass products. H62 brass has good mechanical properties, good corrosion resistance and better plasticity in hot or cold condition, it is easy to machine, braze and weld, but also easy to produce corrosion cracking, it can be used for parts need to withstand large load and the is a good material for making faucets. Common uses of H62 brass including pin, nut, washer, radiator, sugar industry, shipbuilding industry, paper industry, and other parts.
FAQ
| What is H62 brass? H62 brass is a high-quality copper-zinc alloy. It contains 62% copper and 38% zinc. H62 brass has great corrosion resistance, mechanical strength, and workability. That's why people use it in all kinds of industrial applications. |
| Is H62 brass better than 360 brass? H62 Brass: Offers good strength, ductility, and corrosion resistance, making it suitable for forming and bending operations. 360 Brass: Known for its exceptional machinability due to the added lead, but it is slightly less ductile compared to H62. |
| What is the difference between H65 and H62 brass? H62 brass, with slightly lower copper content, is versatile and widely used in plumbing, electrical components, and hardware. In contrast, H65 brass boasts higher tensile strength, better corrosion resistance, and superior machinability, making it ideal for decorative items, musical instruments, and radiator cores. |
| What is the difference between H59 and H62 brass? Their primary differences lie in their composition; H59 contains slightly less copper, making it more malleable but less corrosion-resistant than H62, which contains higher levels of copper for increased durability and environmental resistance. |
| What is H62? H62 is a brass-zinc alloy containing 60.5–63.5% brass. It has good mechanical properties and electrical conductivity. Although cost-effective, it is susceptible to dezincification corrosion, making it suitable mainly for general structural parts. |
| What is the tensile strength of H62 brass? Tensile strength ≥ 330 MPa, elongation ≥ 10% (in the hard state), excellent cold/hot working performance. Suitable for processes such as stamping, drawing, forging, etc. |
