C26800 Brass Material With Fine Corrosion Resistance & Extra Strength
Background
Brasses are alloys of copper and zinc. They may also contain small amounts of other alloying elements to impart advantageous properties. Brasses have high corrosion resistance and high tensile strength.
Properties of Brasses
Brasses are copper zinc alloys with a wide range of engineering uses. The addition of zinc to copper raises the strength and gives a range of properties, and the brasses are a very versatile range of materials. They are used for their strength, corrosion resistance, appearance and colour, and ease of working and joining. The single phase alpha brasses, containing up to about 37% zinc, are very ductile and easy to cold work, weld and braze.
Clarify :
There are many brasses, with properties tailored for specific applications by the level of addition of zinc. Minor amounts of other alloying elements may also be added.
Performance :
The generic term ‘brass’ covers a wide range of copper-zinc alloys with differing combinations of Properties, including:
• Strength • Machinability
• Ductility • Wear resistance
• Hardness • Colour
• Conductivity • Corrosion resistance
