Difference Between Red Brass and Yellow Brass

Red Brass and Yellow Brass

Do you need clarification about the differences between red brass and yellow brass? Don’t worry; you’re not alone. Both red and yellow brass are popular choices for various applications, but they are two distinct metals with different properties. So let’s take a look at what sets these two alloys apart.


Red Brass vs Yellow Brass – What’s the Difference

Chemical Composition

The main difference between red brass and yellow brass is their chemical composition. Red brass contains 85% copper and 15% zinc, while yellow brass contains 80% copper and 20% zinc. This slight variation in the ratio of copper to zinc makes each alloy suitable for different uses.

Strength and Durability

The additional zinc content in yellow brass makes it stronger than red brass, making it more suitable for items that require strength, such as valves or plumbing fixtures. On the other hand, red brass is much softer than yellow brass and can be used in applications where strength isn’t an issue, such as decorative pieces or jewelry. It can also be machined more easily than yellow brass due to its softness.


Since red brass requires less material to manufacture than yellow brass, it tends to be cheaper than its counterpart. This makes it a popular choice for those working on a tight budget who still need a reliable product that won’t break down quickly. If you want something that can withstand wear and tear over time, though, then you may have to opt for the more durable (but more expensive) option of yellow brass instead.



In short, some key differences between red and yellow brasses should be considered when deciding which one is right for your project or application. Red brasses tend to be softer and cheaper, while yellow brasses offer greater strength and durability at the cost of being slightly pricier than their counterparts. No matter which type of alloy you choose, you can rest assured knowing that both will provide excellent performance that meets your needs!
