From its golden appearance to its excellent mechanical properties, Cu-Zn brass has found applications across industries ranging from instalatérství to musical instruments. But what makes this alloy so special? Why do engineers and manufacturers keep turning to Cu-Zn brass for their projects?

In this ultimate guide, we’ll dive deep into everything you need to know about Cu-Zn brass—whether you’re selecting materials for a new product or just curious about its properties. We’ll cover the basics, types, applications, and some insider tips on how to get the most out of this highly adaptable alloy.

Overview of Cu-Zn Brass

What is Cu-Zn Brass?

Její jádro, Cu-Zn brass is a mixture of měď a zinek, typically with a obsah mědi v rozmezí od 55% to 95%, a zinek making up the remainder. The exact ratio of copper to zinc can significantly alter the material’s properties, making brass more malleable, silnějšínebo dokonce more corrosion-resistant depending on the intended application.

Unlike bronz (which is primarily copper and tin), Cu-Zn brass is known for its zlatý odstín, which makes it an attractive choice for decorative applications, in addition to its funkční použití.

Key Characteristics of Cu-Zn Brass

• Odolnost proti korozi: While not as corrosion-resistant as pure copper, brass still holds up well in atmospheric conditions, especially in terms of tarnish resistance.
• Poddajnost: The zinc content makes brass more malleable than copper, allowing it to be easily shaped into complex forms.
• Good Strength: Depending on the zinc content, brass can exhibit impressive tensile and yield strength, making it suitable for structural applications.
• Elektrická vodivost: Brass retains some of copper’s good electrical conductivity, though it’s less conductive than pure copper.
• Zpracovatelnost: Cu-Zn brass can be easily worked, either by kování, odlévání, nebo obrábění, making it a favorite in manufacturing industries.

Types, Composition, and Properties of Cu-Zn Brass

Vlastnosti Cu-Zn brass can be finely tuned by adjusting the ratio of copper to zinc, and in some cases, adding trace amounts of other elements like olovo, cín, nebo hliník. Each type of brass has specific advantages depending on the design requirements.

Types and Composition of Cu-Zn Brass

Alpha Brass

Alpha brass is highly ductile and easy to work with, making it great for zpracování za studena procesy jako rolling nebo razítkování. Běžně se používá v dekorativní předměty, šperky, a hudební nástroje.

Beta Brass

On the other hand, Beta brass is much tvrdší a silnější, though less ductile. This makes it ideal for applications where síla is more important than malleability, such as in převody a ventily.

Mechanical and Physical Properties of Cu-Zn Brass

The mechanical properties of Cu-Zn brass vary widely based on its composition, but here’s a general breakdown of what you can expect from some of the most common types.

Applications of Cu-Zn Brass

Cu-Zn brass is known for its všestrannost. Its uses span across industries due to its zpracovatelnost, odolnost proti korozi, a estetická přitažlivost. Let’s break down some of the most common applications of this alloy.

Common Applications of Cu-Zn Brass

Plumbing and Electrical Applications

Perhaps one of the most recognizable uses for Cu-Zn brass is in instalatérství. Brass fixtures, valves, and vodovodní baterie are ubiquitous in homes and commercial buildings because brass can withstand water corrosion a zároveň nabízí trvanlivost a spolehlivost.

Na adrese elektrické aplikace, brass is prized for its vodivost a obrobitelnost. While not as conductive as pure copper, brass is still a great choice for elektrické konektory a terminály, especially in environments where odolnost proti korozi je klíčová.

Hudební nástroje

When you think of brass, musical instruments like trumpety a trombones probably come to mind. Brass is highly valued in instrument-making for its akustické vlastnosti. The material’s ability to be formed into složité tvary při zachování síla a vibrational qualities je ideální pro dechové nástroje.

Specifications, Sizes, and Standards for Cu-Zn Brass

When sourcing Cu-Zn brass, it’s important to understand the specifikace, velikosti, a průmyslové normy that govern this material. Whether you’re buying raw brass stock nebo zakázkové díly, knowing the třídy a normy will ensure you get the right material for your project.

Common Specifications, Sizes, and Industry Standards for Cu-Zn Brass

Brass is often produced in accordance with ASTM, DIN, a EN standards, which cover everything from chemické složení na mechanické vlastnosti. Například, ASTM B16 specifies requirements for free-cutting brass rods, zatímco EN 12164 obaly brass bars for machining.

Suppliers and Pricing of Cu-Zn Brass

The price of Cu-Zn brass can fluctuate based on factors like obsah zinku, formulář, velikost, a objednané množství. Kromě toho market values z měď a zinek play significant roles in determining the overall cost.

Leading Suppliers and Pricing Estimates for Cu-Zn Brass

On average, prices for Cu-Zn brass range from $5 to $14 per kg, v závislosti na type a formulář. Bary, tyče, a listy tend to be on the lower end of the scale, while custom castings nebo vysoce přesné díly can command premium prices.

Comparing the Pros and Cons of Cu-Zn Brass

Like any material, Cu-Zn brass has its výhody a omezení. While it shines in areas like zpracovatelnost a odolnost proti korozi, there are some trade-offs to consider—such as náklady a vodivost compared to other metals.
