C10100 Characteristics and Applications Overview:
Red copper that is pure copper, also known as copper, has good electrical and thermal conductivity, excellent plasticity, easy to hot press and cold pressure processing, a large number of manufacturing wires, cables, brushes, EDM special copper etching and other requirements of good electrical conductivity of the product. That is, red copper. By sulfide or oxide copper ore smelting of pure copper, can be used to cast money and make artifacts. Uses: Can be used in electrical appliances, steam building and chemical industry, especially the terminal printed electrical circuit board, wire masking with copper tape, air cushion, bus terminals. Electromagnetic switches, pen holders, roofing boards and so on.
Making the master mold: The master mold is the basic mold of the casting, which is used to make the press mold. The master mold can be made from appropriate materials according to the design plan.
C10100 oxygen-free copper cold and hot working properties are excellent. Good malleability. Can be used as a busbar, waveguide, the introduction of electronic tubes and anode, vacuum sealing parts, transistor components, speed control tubes, microwave tubes, rectifiers.

Pressure molds: Pressure molds are special castings for wax molds and can be made of fusible alloys, gypsum, or silicone rubber. Silicone rubber to make pressure mold, the mother mold evenly brushed with pressure mold commonly used steel or aluminum alloy processed, small quantities of layers of silicone rubber, and then paste a layer of gauze, and so on for five or six times, depending on the size of the casting to decide. The outer layer is fixed with plaster, and when the silicone rubber mold is cured, take out the mother mold, that is, turn over the silicone rubber mold compression mold.
C10100 physical properties:
Density of red copper: 8.96g / (cm) specific gravity of red copper: 8.89g / (mm) Cu ≥ 99.95% O < 003 conductivity ≥ 57ms / m hardness ≥ 85.2HV
Making wax molds: The materials for making wax molds are paraffin, beeswax, stearic acid and rosin, etc. 50% paraffin and stearic acid are often used as the mixture. Pour the melted wax into the mold, and keep turning the mold to make the wax uniformly form the wax mold, and take out the wax from the mold after it cools down, and trim the burr to get the wax mold.
