The usual commercial supplies of pure copper are used for the most critical of electrical applications such as the production of fine and superfine enamelled wires. It is essential that purity is reproducibly maintained in order to ensure high conductivity, consistent annealability and freedom from breaks during rod production and subsequent wire drawing. Since the applied enamel layers are thin but have to withstand voltage, they must have no surface flaws; consequently the basis copper wire must have an excellent surface quality. Primary copper of the best grade is used for producing the rod for this work. Uncontaminated recycled process scrap and other scrap that has been electrolytically refined back to grade 'A' quality may also be used.
Equipment
Safran Metals uses state of the art equipment to classify, process and produce a high quality product.
- 54 x 40 American Twin Roll Shredder with Feed Hopper and Hydraulic Power Pack – The first machine in our copper chopping line allows us to sort and chop a significant amount of metal in a short time frame.
- Niton Analyzer – Our X-Ray Niton Analyzer allows us to get the exact component of any metal, allowing us to classify each piece of metal correctly.
- Wire Chopping Line – We can process copper wire effectively while removing insulation, producing a pure copper byproduct.
- Cutting Shears – Safran Metals can cut wire and metal into specific lengths and sizes per the requirements of any customer.
