Insights on Corrosion Resistance

Red Brass

It has high copper content and with the addition of tin, it has increased ability to combat corrosive agents thus suitable for plumbing, boat accessories and other parts that are exposed to water and chemicals.

Yellow Brass

The process of dezincification is also a type of corrosion in which only zinc atoms are dissolved in the solution leaving behind a material with large holes and hence weak in strength. Therefore, yellow brass will be relatively inferior when used in conditions where it comes into contact with corrosive substances for a long duration of time.

Durability Differences – Red Brass Vs Yellow Brass

Red Brass

Due to its anti-corrosive and durability nature, it is used in places where it is needed to offer long service and durability. The presence of tin also improves its sturdiness making it ideal to use in down pipes, showers, around marine areas and such related purposes.

Yellow Brass

However, due to its high strength and hardness it is applicable in mechanical application where the major demand is on its strength rather than on corrosion resistance. It is employed in ornaments, music instruments, and many more products that require beauty as well as strength.

Similarities between Red Brass and Yellow Brass

• Composition: Red and yellow brass are copper-zinc alloy, Red brass contain more copper and Zn while yellow brass is relatively contain Zn more than copper.
• Workability: Despite the differences, both the types of brass are relatively easy to shape and to machine making them suitable to be used in many applications.
• Conductivity: Both are good conductors of electricity, though redbrass has better conductivity slightly by the virtue of having a few percentage more of copper.
• Aesthetic Appeal: Both the types of brass have a shiny look to it, and thus are used for appearance related application and components that will be visible.

Red Brass Vs Yellow Brass: Which Is Stronger?

Although they are both copper-zinc alloys, yellow brass is produced with slightly higher levels of zinc than red brass hence it is stronger. The rise in mechanical strength makes yellow brass suitable for situations where there is a lot of stress and the structure is weak. Corrosive actions act quickly on the Red brass, it is mainly due to the lesser hardness association. You cannot put this metal to usage in heavy demanding areas.

Is Red Brass Better Than Yellow Brass?
