We are a world-class supplier of engineering raw materials. Our objective is to provide all our customers, from the small machine shop to the large multi-national corporation, a supply path that continuously delivers the highest levels of service, quality and value.
C111 (CW114C) is a free-machining sulphur copper with a machinability rating of approximately 80% (free machining brass=100%).
Commercially pure coppers are not the easiest metals to machine due to the material's softness. However, by introducing other alloying elements such as sulphur, this creates a free-machining copper, with only slightly reduced conductivity. The addition of sulphur to the copper results in the effect of cutting the chips into short pieces - this enables a much higher machining speed than is possible with pure copper (up to 4 times). The material also promotes better tooling life expectancy.
C111 still retains high levels of electrical and thermal conductivity. It is a cost effective material since it can be machined at very high speeds without excessive tooling wear. C111 also offers a freedom from hydrogen embrittlement due to the addition of phosphorus in the deoxidisation process. Other benefits of the alloy include very good formability, it can be easily joined by soldering and offers high corrosion resistance.
Commercial applications for this engineering material include:
We stock C111 in flats, round bar, square bar and hexagon bar.
Our knowledgeable staff and resident metallurgists will be pleased to assist you further on any technical topic. Smiths Metal Centres Limited also boasts an in-house UKAS Accredited Testing Laboratory which is unique within the multi-metal and plastic stockholding sector. We believe this underlines our total commitment to quality and our ethos of being the complete service provider.
