Common types of scrap copper introduction

1th copper No.1 Copper Wire 1: includes nudity, no coat, no pure copper alloy, free oxidation without filament, copper wire diameter not less than 1.6mm. Level 2: includes clean, no color, no coat, Wuxi, without alloy the pure copper wire and copper cables, no filament and burnt pieces of copper wire. BarleyBerry
oxygen free copper is elemental copper, solid red, if simple substance copper heating, it will react with oxygen, copper oxide, which is oxygen-containing copper, solid, black.
2 No.2 Copper Wire, copper wire-free alloy scrap copper wire, containing miscellaneous materials, copper content of 96% (minimum content of 94%). Shall not contain excessive lead and Tin-copper wire, welding of copper, brass and bronze wire, excessive oil, scrap iron and steel, and non-metallic, crisp linear, insulated copper wire and a plethora of fine silk thread. Need clear dust in an appropriate manner. Birch
copper is mainly look at his color, copper, copper is a good copper. There are brass, color hair light. There are copper plated zinc, Tin plated, white, there is a poor-quality copper, copper impurities, bent broke into two pieces by hand, inside black trash waste
wire--level 1: plain enamel wire, free of impurities. Level 2: high temperature paint, oxide layer on the surface, free of impurities.
copper is mainly look at his color, copper, copper is a good copper. There are brass, color hair light. Also some copper Shang plating has a zinc, some plating Tin, sent white, also has a inferior copper, copper inside has impurities, with hand a bent on broken into two cut, inside has black impurities
special purple miscellaneous copper various pure copper waste, main including copper material factory and copper processing factory produced of pure copper of scrap, and cut head, and waste times material, and semi-finished products, and wire, and waste,; allows has scrap of pure copper bare and copper tube, other pure copper products, but no has scale, and oil, and coating,; waste copper material in the not allows contains any impurities and copper alloy, No filament, turnings, debris and thickness of less than 1 mm of copper.

1, purple miscellaneous copper No.l Heavy Copper should including clean of, and no alloy, and no coating of processing scraps, and conductive Board and diameter is greater than 1.6 mm of copper, material in the allows with clean of copper tube and other pure copper block material, containing copper volume for 98% (minimum containing copper volume is greater than 96%). No burned crisp quality copper wire. Candy
guaranteed to air, soil, water and environmental pollution cases, e-waste recycling and to some extent can be used. Common recycling of waste electronic equipment parts as well as manual dismantling processing methods are as follows:
electronic equipment enclosure is usually made up of iron, plastic, steel, or aluminum. Therefore, can be recycled from electronic waste plastics and metals such as iron, steel, aluminum, and secondary use.
TV and monitor picture tube glass in, can be a lot of glass recycling, it should be noted that the glass is full of lead, arsenic and other toxic metals pollute the environment, no special equipment can not be recycled, not thrown away can be used as a display of glass recycled material recycling, and other glass can also be used as additives. Picture tube deflection yoke on the stem is made of copper, copper can be recycled.
used in air conditioning, refrigeration equipment, evaporators, condensers, high-precision aluminum and copper, you can do a lot of recovery, but note that these refrigerants in air conditioning, refrigeration freon, ozone has been devastating, so, in front of the dismantling, must be collected in advance to prevent freon leak.
electric motors (including air conditioning compressor that is used on a variety of fan) electronic apparatus, because the motor is made up of steel, magnets, copper windings, iron, magnet, copper can be recycled.
most of the waste electronic equipment with electronic circuit boards, which contain a large amount of scrap electronics, metal Tin soldering on the circuit board, using special equipment for Tin, iron, copper, aluminum recycling.
most of the electronic devices are mechanical bodies, generally iron or plastic, steel, iron, plastic, steel can be recycled.
2 impure copper No.2 Copper mixed copper scraps should be included, not including copper alloy, copper content of 96% (minimum content of 94%). Shall not contain excessive lead and Tin, welding of copper scrap, too much oil, steel, non-metallic waste, non-copper connectors copper pipe or a copper pipe with residue, burnt or insulated copper wire, filament, burned crispy quality copper wire, clay and so on.
