At S & D Non-Ferrous, we stock Sulphur Copper in Grade CW114C, a free machining copper with an approximately 80% machinability rating.
Adding sulphur to copper produces a ‘free machining copper’ as the sulphur acts as a chip breaker, making it far easier to machine than pure copper and only having a minor effect on the conductivity of the metal.
Machining speeds can reach up to 4 times faster than those of pure copper and greater tooling life span is also seen when using sulphur copper over pure copper.
Sulphur Copper is a versatile metal as it combines the high thermal and electrical conductivity values that are usually only seen in pure copper, however the ease of machining from the sulphur, allowing it to be used in a greater number of circumstances. Other qualities of CW114C are easy solder ability and decent levels of corrosion resistance.
Our CW114C sulphur copper is readily available in a number of formations, including sulphur copper plate or sulphur copper bar in a range of shapes. Our team will be happy to discuss these with you in further details if you are unsure of the exact product you need.
We source all of our sulphur copper from UK and European suppliers to ensure our customers only receive high-quality stock that meets and exceeds industry standards.

Sulphur copper is the addition of sulphur to a standard copper. Pure copper has excellent thermal and electrical conductivity, as well as great ductility and corrosion resistance, but the metal has poor machinability.
When sulphur is introduced to copper, the workability of the metal significantly increases, without having to compromise on the favoured and beneficial aforementioned properties. Pure copper has a machinability rating of 20%, in contrast to sulphur copper that has an 80% machinability rating.
Sulphur copper has machining speeds that are four times faster than pure copper and since the compound produces a much softer metal, it is less detrimental on tooling and machining components.
Sulphur copper is used in applications that require good corrosion resistance, excellent thermal and electrical conductivity, but also applications that demand easy forming and extensive machining that pure copper is unable to handle.
Some examples of these applications include:
Circuit Breakers
Electrical Connectors
Socket Connectors
Laser Nozzles
Transistor Bases
Relay Parts
Electrical Pins
