| Rich Low Brass Wire | CuZn (Special alloy) | 4-30 gauge | Jewelry making, decorative items | Soft, high ductility |
| Hard Brass Wire | CuZn (Higher Zn) | 8-20 gauge | Springs, mechanical parts | Increased strength, lower ductility |
| Annealed Brass Wire | CuZn (Reduced stress) | 8-24 gauge | Cold stamping, intricate designs | Excellent workability |
| Half-Hard Brass Wire | CuZn (Medium strength) | 16-20 gauge | Earring wires, light-duty applications | Balance of strength and ductility |
Types of Brass Wire
Brass wire comes in several types, each suited for specific applications. Understanding these types can help you make an informed choice.
Yellow Brass Wire
Yellow brass wire is one of the most common types used in various applications. Its composition, typically around 65% copper and 35% zinc, offers good corrosion resistance and reasonable electrical conductivity. It’s widely used in the manufacture of electrical connectors and mechanical fasteners.
Rich Low Brass Wire
Rich low brass wire, often referred to as “jeweler’s brass,” contains a special alloy that gives it a beautiful gold-like appearance. This type is favored in jewelry making due to its soft texture and malleability, making it easy to work with for intricate designs. It’s known by various names, including Merlin’s Gold and Nu Gold.
Hard Brass Wire
Hard brass wire has a higher zinc content, making it stronger and more rigid. This type is commonly used for applications where durability and strength are critical, such as in the production of springs and mechanical components. While it has lower ductility, it compensates with enhanced performance under stress.
Annealed Brass Wire
Annealed brass wire is treated to reduce stress and improve workability. This type is ideal for cold stamping applications and intricate designs that require bending and shaping. Its excellent workability makes it a popular choice among manufacturers.
Half-Hard Brass Wire
Half-hard brass wire strikes a balance between strength and ductility, making it suitable for applications like earring wires and light-duty projects. This type maintains some flexibility while providing enough strength for various uses.
Applications of Brass Wire
Brass wire has a wide range of applications across different industries. Understanding these applications can help you determine which type of brass wire is best suited for your needs.
Electrical Engineering
In the electrical engineering sector, brass wire is used for connectors, terminals, and other components that require good conductivity and corrosion resistance. Its durability makes it ideal for both indoor and outdoor applications.
Jewelry Making
Rich low brass wire is highly sought after in the jewelry-making industry. Its aesthetic appeal, combined with its workability, allows artisans to create beautiful pieces that can be polished, oxidized, or left to develop a natural patina.
Mechanical Fasteners
Various types of brass wire are used in the production of mechanical fasteners, such as screws and bolts. The strength and corrosion resistance of brass make it suitable for applications in automotive and aerospace sectors.
Springs and Other Components
