Cast Brass

Cast brass is made of copper and zinc, with the primary phase being alpha copper. The chemical composition of cast brass can vary depending on the type of brass and its intended use.

Material Properties

Cast brass has many properties, including:
Strength: Cast brass is strong and elastic, especially when it contains more zinc.
Corrosion resistance: Cast brass is resistant to corrosion in many media, but it can corrode in solutions containing ammonia or amines.
Malleability: Cast brass is malleable, meaning it can be easily shaped.
Ductility: Cast brass is ductile, meaning it can be stretched without breaking.
Low friction: Cast brass has low friction, making it useful in applications where sparking is undesirable.
Low melting point: Cast brass has a relatively low melting point.
Good conductor: Cast brass is a good conductor of heat.
Anti-microbial: Cast brass has anti-microbial properties.
Desirable acoustic quality: Cast brass has a desirable resonance and acoustic quality.

Material Chemical composition

Copper: Typically the larger proportion, usually around 66%
Zinc: The amount of zinc determines the color of the brass, with more zinc making it more yellow
Other metals: Iron, aluminum, silicon, and manganese are sometimes added to create different properties and colors
