What is the composition of brass fittings？

Brass fittings are typically made from an alloy of copper and zinc. The composition of brass can vary, and different alloys are used for specific applications based on the desired properties. The most common types of brass alloys used for fittings include:
Alpha Brass (Low Zinc Brass):
Composition: Approximately 65% copper and 35% zinc.Properties: Good corrosion resistance, high ductility, and ease of cold working. Commonly used for general-purpose fittings.
Alpha-Beta Brass:
Composition: Approximately 55-65% copper and 35-45% zinc.Properties: Balanced combination of strength and ductility. Suitable for a wide range of applications, including fittings in plumbing.
Beta Brass (High Zinc Brass):
Composition: Approximately 55% copper and 45% zinc.Properties: Higher strength and hardness compared to alpha brass. Often used in fittings where greater strength is required.
Lead-Free Brass:
Composition: Various formulations, but typically contains less than 0.25% lead.Properties: Meets lead-free regulations for potable water systems. Commonly used in modern plumbing applications.
DZR Brass (Dezincification Resistant Brass):
Composition: Typically contains additional alloying elements like arsenic or tin to resist dezincification.Properties: Resistant to corrosion in aggressive environments, making it suitable for applications with high levels of dezincification potential.

What are the key mechanical properties of brass fittings？

Brass is a popular material for fittings due to its favorable combination of mechanical properties, corrosion resistance, and workability. The key mechanical properties of brass fittings include:
Tensile Strength: Tensile strength is the maximum amount of tensile (pulling) stress that a material can withstand without breaking. Brass typically has a high tensile strength, making it suitable for applications where the fitting needs to withstand significant forces.
Yield Strength: Yield strength is the amount of stress a material can withstand without permanent deformation or, in the case of brass, without undergoing plastic deformation. Brass generally exhibits a well-defined yield point, and the yield strength is a crucial parameter in determining the material's behavior under load.
Elongation: Elongation is a measure of how much a material can stretch before it breaks. Brass fittings often have good elongation values, indicating their ability to deform before failure.
Hardness: Brass can be easily machined and has a relatively low hardness compared to some other metals. The hardness of brass fittings can vary depending on the alloy composition and heat treatment.
Impact Resistance: The ability of brass to absorb energy without breaking or cracking is an essential property, especially in applications where impact forces may occur. Brass fittings generally exhibit good impact resistance.
Fatigue Strength: Brass has reasonable fatigue resistance, meaning it can withstand repeated cycles of stress without failure. This is important in applications where fittings may experience cyclic loading.
Machinability: Brass is known for its excellent machinability, making it easy to shape into various fittings and components. This property contributes to its widespread use in manufacturing.
Corrosion Resistance: While not a mechanical property per se, the corrosion resistance of brass is a crucial characteristic. Brass resists corrosion, making it suitable for applications where exposure to moisture or corrosive environments is a concern.
