Brass

overview

Brass Manufactured Products

Brass is an alloy of copper and zinc (generally composed of 65% copper and 35% zinc), the proportions of which can be varied to achieve a range of brasses with varying properties.
A higher percentage of copper yields greater ductility whereas a higher percentage of Zinc would increase the working strength at colder temperatures.

Brass flanges have various features including their ability to be great thermal conductors and their resistance to corrosion, along with being high strength but light in weight.
Brass is used across the oil, gas and chemical industries whilst also being highly used in marine, water and wastewater treatment plants.

Advantages of Brass

  • Thermal Conductivity – Brass has an excellent thermal conductivity (between 23 – 44%) of pure copper making it a first choice for heat exchangers.
  • Durability – Brass is a very durable material that does not crack or rust easily making it last significantly longer than other metals.
  • Excellent Machining Qualities– Brass being a relatively soft material makes it easy to machine.
  • High Density– With brass having a high density, it makes it ideal for heavy industrial parts.

CZ112 (Naval Brass)

As suggested by its name, CZ112 (C46400 related spec) is commonly known as Naval brass.
The reasoning behind this is due to the addition of 1% tin that gives an improved corrosion resistance enabling this material to be used in lightly aggressive circumstances, for example sea water and marine components including heat exchanger tube plates (an example of which can be found on our news page, manufactured by JRW)
