Ingredients：Copper CU Ag: 99.90 Oxygen O balance. Conductivity ≥56ms/m, tensile strength Mpa≥295, density 8.9g/cm
Introduction to Features：Pure copper is a rose-red metal, and it turns purple after a copper oxide film is formed on the surface, so industrial pure copper is often called red copper or electrolytic copper. Fire refining can obtain 99-99.9% pure copper, and electrolysis can make the copper purity reach 99.95-99.99%. The density is 8-9g/cm3 and the melting point is 1083°C. Pure copper has good electrical conductivity and is widely used in the manufacture of wires, cables, brushes, etc.; it has good thermal conductivity, and is often used to manufacture magnetic instruments and instruments that must be protected from magnetic interference, such as compasses, aviation instruments, etc.; good plasticity, easy to hot-press and Cold pressure processing, can be made into tubes, rods, wires, strips, strips, plates, foils, etc. There are two kinds of pure copper products: smelted products and processed products. The product specifications are complete, the price is favorable, the packaging is intact, the copper quality is pure, the straightness is good, the inventory is large, and the material certificate can be provided. Copper is relatively pure copper. It fully expresses the ductility, conductivity and corrosion resistance of metallic copper, of which ductility is an important feature of copper ornaments. The high melting point of red copper makes it difficult to cast, and its good ductility makes up for this shortcoming, so it can be easily processed into various shapes and patterns. The dark red metallic luster gives it a calm and noble quality while expressing a modern sense, and is the most commonly used material in copper ornaments.
The use of copper tape：High purity, fine tissue, low oxygen content. No pores, trachoma, looseness, good electrical conductivity, high precision of the surface of the mold etched by electricity, after heat treatment process, the electrode is non-directional, suitable for fine drilling, fine drilling, with good thermal conductivity, processability, ductility, anti-corrosion corrosion resistance and weather resistance. It has good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, and can be welded and brazed.
