TELLURIUM COPPER

S&D hold a wide range of C14500/CW118C high quality oxygen free machining rods, and flats.

The addition of Tellurium significantly improves the machining speed to 80% plus  when compared to leaded brass. Standard copper being 20%.

At the same time the small addition of tellurium only reduces the thermal conductivity slightly to 93-94% which makes it very suitable for close tolerance high voltage connectors.

 As with all of our products we are committed to sourcing and selling through proven high quality suppliers.

 Our current range includes round bars from 3mm -100mm  and flat bars from 4-8” wide.

Should you have a requirement outside of our stock range, we will always look to offer a bespoke solution.

To learn more about our range of tellurium copper or for advice on the best products for you, please don’t hesitate to call us today on 0121 525 5500.

Tellurium Copper Bar & Rod

S & D Non-Ferrous stocks Sulphur Copper bars 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 noticeably easier to machine than pure copper and only having a minor effect on the conductivity of the metal.

The speed of machining can reach up to 4 times faster than those of pure copper. It has a greater tooling life span is also seen when using sulphur copper over pure copper. Sulphur Copper is a multipurpose 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 allows it to be used in a greater number of circumstances. Other qualities of CW114C have an easy solder ability and decent levels of corrosion resistance.

Our CW114C sulphur copper bars 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 from UK and European suppliers to make sure our customers only receive top-quality stock that meets and exceeds industry standards. To discover more about our range of sulphur copper, please do not hesitate to contact a member of our knowledgeable S & D team today on 0121 525 5500.

Tellurium Copper Plate

S & D Non-Ferrous has a brilliant stock of tellurium copper plates in CW118C – a form of free machining oxygen free copper. Tellurium copper’s machining qualities are significantly improved upon those of pure copper, due to the addition of alloy. The machinability rating of pure copper is 20% compared with tellurium copper at 90% and the electrical and thermal conductivity is only slightly reduced.

Tellurium Copper plates are formed through refining, melting and casting for the production of the final product, however it is crucial that all oxygen is removed in order to achieve a resistance to hydrogen embrittlement, and also stop oxygen merging with the tellurium that would produce a brittle copper.

We are dedicated to selling only the best-quality metals to our clients, so we source our tellurium copper sheets from UK and European manufacturers. To find out more about our range of tellurium copper, or for advice on the best products for you, please call us on 0121 525 5500.
