Sulphur Copper Plate

S & D Non-Ferrous stocks Sulphur Copper plate in CW114C, a free-machining copper with a great, approximately 80% machinability rating. Adding sulphur to copper makes for a ‘free-machining copper’ as the sulphur acts as a chip breaker, making it markedly easier to machine than pure copper and only having a small effect on the conductivity of the metal.

Sulphur Copper’s machining speeds can reach up to 4 times faster than those of pure copper. It has a better tooling life span. Sulphur Copper is a flexible metal as it combines the high thermal and electrical conductivity values that are often seen in pure copper, however, the ease of machining from the sulphur allows it to be used in a greater number of conditions. Other qualities of GRADE have an easy solder ability and decent levels of corrosion resistance.

Our CW114C sulphur copper plates are readily available in a number of other formations, too. Our team will be happy to discuss these with you in further detail, if you are unsure of the exact product you need.

We source all of our sulphur copper plates from UK and European suppliers to make sure our customers only receive top-quality stock that meets industry standards.
