Introduction
If you’ve ever wondered what is brass made of, you’re not alone. From door handles to electrical parts and industrial fittings, it is everywhere. At OK Engineers, brass is more than just a metal—it’s a reliable material trusted across engineering and industrial applications.
So why does brass continue to dominate even in 2026, when advanced alloys and composites are everywhere? The answer lies in its simple chemistry, versatility, and cost-effectiveness.
Why Brass Still Matters in Modern Industries – It strikes a rare balance. It’s strong but workable, durable yet affordable. Engineers love it because it machines easily, resists corrosion, and looks good doing it.
Brass in Everyday Life – Plumbing valves, musical instruments, decorative items, bearings—you’ve touched brass more times today than you realize.
What Is Brass Made Of?
At its core, brass is an alloy, meaning it’s made by mixing metals.
Primary Elements
Copper – The Base Metal
Copper forms the foundation. Typically, brass contains 55% to 95% copper. Copper gives:
- Excellent conductivity
- Natural corrosion resistance
- A warm, golden color
Zinc – The Strength Enhancer
It iss the second main ingredient, usually 5% to 45%. Zinc:
- Increases strength
- Improves hardness
- Makes easier to machine
Together, copper and zinc answer the basic question: what is brass made up of?
Typical Composition Ratios
| Brass Type | Copper (%) | Zinc (%) |
| Alpha Brass | 65–70 | 30–35 |
| Cartridge Brass | 70 | 30 |
| High-Zinc Brass | 55–60 | 40–45 |
What Is Brass Made Of in Different Grades
Not all brass is the same.
Alpha Brass
- High copper content
- Soft and ductile
- Ideal for cold working
Alpha-Beta Brass
- Balanced copper and zinc
- Stronger and harder
- Used in valves and fittings
High-Zinc Brass
- Maximum strength
- Lower corrosion resistance
- Used in heavy-duty components
What Is Brass Made Out Of Besides Copper and Zinc?
Sometimes, manufacturers add small amounts of other metals.
Lead
- Improves machinability
- Common in free-cutting brass
Tin
- Enhances corrosion resistance
- Used in marine environments
Aluminum
- Adds strength
- Improves oxidation resistance
Nickel and Iron
- Increase hardness
- Improve wear resistance
So when people ask what is brass made out of, the answer can vary based on application.
Brass Made of What Materials Determines Its Properties
The exact mix defines how brass behaves.
Strength and Durability – More zinc = stronger brass. This is why industrial components from OK Engineers often use carefully balanced alloys.
Corrosion Resistance – Higher copper content improves resistance, especially in moist environments.
Electrical and Thermal Conductivity – It conducts electricity better than steel, making it suitable for electrical fittings.
The Simple Chemistry Behind Brass
Let’s keep it simple.
Alloying Process Explained Simply – When copper and zinc are melted together, their atoms mix evenly. This creates a new material with properties better than either metal alone.
How Zinc Changes Copper’s Behavior – Zinc atoms distort copper’s crystal structure. Think of it like adding stones to cement—it becomes tougher.
Manufacturing Process of Brass
Melting and Mixing – Copper is melted first, then zinc is added carefully to prevent evaporation.
Casting and Forming – The molten brass is cast into billets, rods, or sheets.
Finishing and Quality Control – At OK Engineers, strict quality checks ensure consistent composition and performance.
Types of Brass and Their Applications
Cartridge Brass
- 70% copper
- Used in ammunition and radiator cores
Naval Brass
- Tin-added brass
- Ideal for marine fittings
Free-Cutting Brass
- Lead-added
- Perfect for precision machining
Why Industries Prefer Brass
Cost-Effectiveness – It offers premium performance without premium cost.

How OK Engineers Uses Brass – At OK Engineers, It is selected based on application-specific needs, ensuring strength, safety, and durability in every product.
Sustainability and Recycling of Brass
Is Brass Eco-Friendly? – Yes. It’s 100% recyclable without losing quality.
Recycling Trends (2026 Update) – Over 90% of industrial brass is now recycled globally, reducing mining and energy use.
Common Myths About Brass
Is Brass Pure Metal? – No. It’s an alloy.
Does Brass Rust? – No, It doesn’t rust like iron. It may tarnish, but that’s harmless.
Choosing the Right Product for Your Application
Factors to Consider
- Strength needs
- Corrosion exposure
- Machining requirements
Expert Tips from OK Engineers
Always match grade to usage. Overengineering costs money; underengineering costs safety.
