Are Bronze Bushings Better Than Brass? A Guide for B2B Buyers
Table of Contents
“A bronze bushing is usually longer-wearing and can handle more load than a brass bushing. A brass bushing is better at standing up to corrosion than a bronze bushing.”
The main reason for this is the composition and structure of the copper alloy. Bronze has tin or other alloying elements giving it better wear, corrosion resistance, and higher strength best suited for heavier loads. Brass, on the other hand, is typically copper and zinc and while it has good corrosion resistance, it doesn’t wear as well, and it is not as strong when you get into higher loads and higher friction.
However, High-Strength Brass Bushing isn’t like regular brass. It has better friction and corrosion resistance and is more suitable for all sorts of heavy-duty construction machinery.
When it comes to figuring out the ideal bushing material for your industrial application, bronze and brass will probably be in your top selections.
Bronze and brass are both copper alloys, but each has properties that make it perfect for different jobs. Here’s what you need to know as a B2B buyer in the engineering, manufacturing, construction, etc. industries to pick the right one for your application. Let’s look at our bronze bushings verses brass bushings comparison based on key factors and performance issues.

What is the Difference Between Bronze and Brass?
Before we dive into whether they are good as bushings, let’s make sure you know the differences between bronze and brass.
As I mentioned, bronze is alloyed from copper and mainly tin, along with other elements such as phosphorous, aluminum, and silicon. Bronze is used where you need additional strength and, in some cases, increased wear resistance, and excellent corrosion resistance, especially in some harsh environments.
The brass alloy is made from copper plus primarily zinc. It has a zinc content typically of 5% to 45%. Brass in general is more ductile than bronze and machines better, but it isn’t as strong as bronze in tougher situations.
Are Bronze Bushings Better Than Brass for Wear Resistance?
Bronze generally outlasts brass when it comes to wear.
People like bronze bushings because generally, they’re stronger and can stand up to a lot of friction. Bronze is exceptional in heavy loading and high-temperature applications like you’ll find in machinery, cars, trucks, and heavy equipment where they’re used frequently.
Brass bushings wear well, but not as well as bronze. Brass bushings tend to wear out a lot more under heavy friction and a high load, which is why you don’t see them used as often.
Why Are Bronze Bushings More Corrosion-Resistant Than Brass?
Which of the two is best from a corrosion standpoint: bronze or brass?
The answer is bronze, because bronze has a natural corrosion resistance, particularly in salt water and marine environments, due to the tin and other elements in the alloy. Bronze is often the choice for marine engineering, offshore equipment, and corrosive environments.
Brass is corrosion resistant in many environments as well, but is subject to dezincification, which is a specific type of corrosion where the zinc leaches out of the material. This can weaken the material and cause it to degrade in water or high-humidity environments.
Which Material Is Better for Lubrication?
Bronze generally has an advantage. It works well in self-lubricating conditions especially if you have a good solid lubricant active in it – such as graphite or PTFE (Teflon). In those instances where it is not reasonable to lubricate externally it keeps on frictioning well on it’s own.
Brass bushings can okay working with lube from the outside, but as a normal course, brass bushings require some maintenance and adding a lubricant to them to keep them working in a high friction area.
Are Bronze Bushings Stronger Than Brass?
Bronze is the better.
It is stronger and has more load-bearing ability. It can handle a lot of stress and a lot of load like heavy machinery without bending, warping, or breaking. Because of this strength, bronze bushings are used extensively in construction equipment, in automotive parts, and in industrial machinery where you need that strength and wear resistance.
Although brass is stronger than many other things, brass is generally not as strong as bronze in high-load-bearing situations. People assume brass is similar to bronze, but it is more maneuverable. It is more ductile (shape changeable) than bronze.
Which Material Is More Cost-Effective?
Brass is cheaper than bronze because it’s easier to machine and requires less energy. This makes it a low-cost source in applications where you need to be cost conscious like Brass is less expensive than .
Bronze comes at a higher price that can provide a better long-term value. It’s more resistant to corrosion, it’s stronger and it has much greater abrasion resistance. If you need something that can handle wear, and heavy loads,especially in highly corrosive applications, then the increased cost of bronze makes sense.
Which One Should You Choose for Your Application?
Whether you choose bronze bushings or brass bushings really depends on your application.
If you have something that needs to be high-load, high-wear, last a long time, be corrosion resistant (like in a marine environment or on heavy equipment), then you want bronze bushings.
If you have something low-load, low-speed, and cost, you might want brass bushings. People have used brass bushings in lots of things for years. Brass is sometimes used for bushings in plumbing, electrical stuff, even cars.
Conclusion: Are Bronze Bushings Better Than Brass?
As a general rule, bronze bushings are better for anti-wear, anti-corrosion and for handling heavier loads you find in a strict mechanical application. But, brass bushings are a more cost-effective solution for applications that don’t justify the more expensive bronze bushing since they don’t have an anti-wear or anti-corrosion benefit.
When you’re buying bronze or brass as a purchaser for a business, the material you choose depends on your needs. If you need something that is tough, will last a long time, and that has high corrosion resistance, then bronze might be the best option for you. If you need something that won’t break the bank and is good enough for what you need to do, then brass is the way to go.
