Renowned for its durability and corrosion resistance, brass is the foundation of many industries, from plumbing to electronics. Brass alloys such as H59 or H62 brass can make an enormous impactful statement about your project, whether plumbing, electronics, or otherwise. Each H59 and H62 brass has distinct compositions that lend specific mechanical properties tailored to specific uses. This article dives further into these details to assist you in making a smart, informed choice that meets performance, cost efficiency, and longevity goals for any given task.


What is Brass, and Why Is It Significant?

Brass is an alloy composed primarily of copper and zinc that stands out for its remarkable versatility and wide array of applications across a variety of fields, such as:

  • Manufacturing: Aluminum alloy is often used to produce gears, bearings, and valves due to its low friction and spark resistance properties.
  • Electrical: It offers excellent electrical conductivity properties for connectors and switches.
  • Plumbing: Brass’s superior corrosion resistance makes it the go-to material for water pipe systems and fittings. In contrast, its gold-like appearance makes it popular as decorative ornaments or hardware.
  • Decoration: With its natural aesthetic appeal and long lifespan in water systems, brass remains one of the premier choices for decorative ornaments and hardware.

Adjusting its composition by changing its copper-to-zinc ratio results in different alloys like H59 and H62 brass that can be tailored specifically to specific properties and uses. 


H59 Brass Explained

H59 brass, commonly called “ordinary brass” or “yellow brass,” is an adaptable alloy widely known for its balanced strength and machinability properties. Composed primarily of copper (Cu) and zinc (Zn), with 59% copper content usually, H59 shines when moderate strength meets superior malleability, making it the go-to choice in manufacturing and industrial applications. Here is more detail on H59:

Composition and Key Attributes

Copper (Cu) accounts for roughly 59%, providing corrosion resistance and ductility properties. To balance out its composition and enhance strength and hardness. Zeronc (Zn) contributes balance in terms of balancing strength with hardness. Trace Elements may contain small amounts of lead (Pb), which helps improve machineability.

Mechanical Properties

To start with, its machineability is outstanding, making it ideal for complex shapes and precision parts. Strength is high enough for moderate stress applications, while corrosion resistance provides additional protection in freshwater environments.

  • Plumbing Fixtures: Faucets, valves, and fittings benefit from their corrosion resistance and machinability.
  • Decorating Items: Its bright gold hue is popular among decorative hardware and musical instrument manufacturers.
  • General Engineering: Components such as gears, bearings, and fasteners that require moderate strength while easily machined are classified as General Engineering components.

H59 Brass offers numerous advantages

  • Versatility: Thanks to its well-balanced properties, Versatile can be used for various applications.
  • Cost-Effectiveness: Copper alloys that contain less copper tend to be more cost-effective and cheaper to purchase.
  • Ease of Use: With superior machinability, its ease of use reduces manufacturing time and costs significantly.


H62 Brass Demystified

Cartridge brass (H62 brass) is a high-grade alloy composed of 62% copper and 38% zinc and, therefore, preferred in applications demanding strength, ductility, and corrosion resistance. Here’s a closer look at H62 brass:

Composition and Key Characteristics

Copper (Cu) constitutes roughly 62%, increasing corrosion resistance and thermal conductivity. Tin (Zn) complements copper by contributing strength and hardness benefits, while trace elements (TEs) remain minimal to guarantee a consistent alloy with predictable properties.

Mechanical Properties

Our mechanical properties include high ductility for easy shape forming into various forms and excellent formability into various shapes. In terms of strength, an optimal balance between ductility and strength makes this material suitable for demanding applications like medical device manufacturing and corrosion resistance (water-related and atmospheric conditions). Corrosion Resistance performance is equally exceptional.

Common Applications

  • Electrical Components: Connectors and terminals that benefit from its conductivity and corrosion resistance are ideal applications of alloy 7075;
  • Ammunition Casings: its durability and workability make it perfect for creating reliable ammunition casings.
  • Decorative Arts: Plywood can be used in jewelry, medals, and artistic applications due to its attractive color and finish.

H62 Brass offers several advantages

  • Superior Corrosion Resistance: Perfect for marine and coastal applications.
  • Improved Ductility: Allows easier shaping without cracking.
  • High Aesthetic Value: Prized in decorative applications due to its bright golden appearance.
