A comprehensive range of Brass Alloy products

Our extensive range which are also known as 'yellow metals' maximise alloy performance whilst saving cost. Our alloys offer increased strength, malleability, ductility and resistance to corrosive attack.


Brass Alloys for Engineering Applications

  Also known as 'yellow metal products'
The range of copper alloys known as brasses cover machining alloys, bending alloys, riveting alloys, deep drawing alloys and spinning alloys to name but a few. These descriptions again signify the wide range of applications for which the metal is used.

The addition of aluminium, iron, manganese and silicon to the alloy mixture gives added strength or hardness, whilst the addition of elements such as aluminium, tin and arsenic give improved corrosion resistance. The addition of a controlled amount of lead to brass alloys produces what is known “free machining” brass. Free machining brass is designed specifically for high speed, efficient component manufacture.

Alloy specifications:


During the late 1990s a new series of BS EN standards was brought in for all copper based alloys. The new series of standards brought with it a new system for describing products. The system described products in two ways, one using symbols the other using numbers. The symbol system follows the ISO compositional system and a brass made up of a 63/37 ratio of copper and zinc is shown as CuZn37. The numbering system is a six-character alpha numeric system with two characters (the first of which will be ‘C’ for copper) followed by three numbers and a letter. Using this system CZ121 has become CW614.

This product range includes the old and new numbering systems.
