Brass Fitting-Full Series

1. Alpha Brass (Solid Solution Brass):

Composition: Mostly copper with up to 40% zinc.

Properties: It is highly ductile and can be easily worked, making it ideal for cold working and forming.

Applications: We generally use it in applications like coins, electrical connectors, and small parts like nuts and bolts.

2. Beta Brass (Beta Alloys):

Composition: Contains more zinc than alpha brass, usually between 40% to 50% zinc.

Properties: Beta brass is harder and more brittle than alpha brass, and it is harder to cold work.

Applications: We use it for casting and in situations where high strength is needed.

3. Alpha-Beta Brass (Duplex Brass):

Composition: This is a mixture of both alpha and beta brass, typically with a zinc content of 30-40%.

Properties: It combines the benefits of both types, offering good strength, ductility, and ease of machining.

Applications: This is the most common brass material in manufacturing. We may found in applications like plumbing fittings, radiator cores, and fasteners.

4. Leaded Brass:

Composition: Contains a small amount of lead (around 2-4%) mixed with copper and zinc.

Properties: The lead content improves machinability, making it easier to cut and shape. However, lead can reduce the alloy’s corrosion resistance.

Applications: Commonly used in the manufacturing of precision machined components such as gears, bushings, and electrical fittings.

5. Naval Brass:

Composition: Contains about 60-65% copper, 30-35% zinc, and small amounts of tin (around 1-2%).

Properties: Extremely resistant to corrosion, especially in seawater. The tin addition enhances its ability to withstand marine environments.

Applications: Primarily used in marine environments, such as in ship fittings, propellers, and other seawater-exposed components.

6. Muntz Metal:

Composition: A type of high-zinc brass (about 60% copper and 40% zinc).

Properties: It has good strength and is highly resistant to corrosion, though it can be more brittle than other brass alloys.

Applications: Used in marine hardware, heat exchangers, and architectural elements.

7. High Brass:

Composition: Contains a higher proportion of copper (typically 70% or more) and a lower percentage of zinc.

Properties: It has better corrosion resistance and is more malleable compared to other brasses.

Applications: Used in decorative items, musical instruments, and some types of plumbing fittings.

8. Aluminum Brass:

Composition: Brass alloyed with a small amount of aluminum (usually less than 10%).

Properties: Offers good corrosion resistance, especially in environments with high exposure to water or chemicals.

Applications: Primarily used in heat exchangers and plumbing systems.
