Copper casting is usually made of pure copper or copper alloy through casting processing of metal casting parts, various forms, wide uses, the use of copper or copper alloy metal properties made in line with the production of casting, can be used in a very wide range of products, copper casting products are welcomed by consumers. But occasionally there will be some inevitable defects in copper casting, then it is necessary to use some tools or products to repair it, copper casting defect repair glue is one of them.

Copper casting defect repair adhesive is a new type of reflective type of normal temperature solidification copper casting defect repair adhesive with excellent performance and scientific and reasonable configuration of aluminum alloy, porcelain, diamond and other powders. It is a new adhesive used to repair the defects of copper casting.

After drying, the adhesive has strong bonding strength, acid and alkali resistance, moisture resistance, high temperature resistance, aging resistance and excellent substance resistance. In order to achieve the tone consistency of the copper casting, the dry solid adhesive is brass color.

In addition to sand mold casting, copper casting and other rare metals aluminum alloy are generally adopted by metal casting, extrusion casting, gravity casting, high purity graphite forging and other unique casting methods.

In copper alloy forging, choosing metal casting method to accelerate the condensation of aluminum alloy plays an important role in improving the quality of casting parts and reducing welding defects. Metal casting can refine grain, reduce air vent, and enhance the physical properties and tightness of aluminum alloy.

In lead brass and other high lead alloy copper, the application of metal casting can avoid the shrinkage of copper chemical composition. In addition, because there are more cylindrical parts in copper alloy castings, extrusion casting is often used.

In addition, gravity casting can also be used to increase the density of the alloy and reduce the inclusions formed during forging. Some copper alloys can also be forged according to working pressure.
