How is the wear resistance of purple copper plate under low temperature state

The connection between copper plate and steel is one of them. Copper plate has very good corrosion resistance and high wear resistance and lubrication performance. It is widely used as raw material for the production and processing of prefabricated roller bearings.

However, the commonly used arc welding method can not be used to weld steel and tin bronze, because it will cause the melting and burning of alloy copper elements in the process of electric welding, so that there are air holes in the electric welding, so as to reduce the characteristics of the work. Therefore, diffusion connection is generally selected in the way of connection. Based on the selection of professional diffusion connection and basic parameters of production process, it can be well carried out. Purple copper plate is a non-ferrous aluminum alloy profile with less shrinkage rate, which can be used for the production and processing of cast iron with complex appearance, clear wheel corridor and low tightness requirement.

Copper plate in gas, sea level, fresh water and steam is very resistant to corrosion, widely used in steam boilers and ocean-going ship parts. The solidification range of purple copper plate is large, and the defects of twin casting are serious. During solidification, it is not easy to cause centralized casting defects and the capacity shrinkage is not large. Reverse shrinkage shrinkage of tin is easy to occur in casting. When it is more serious, milk white black spots can be seen on the casting surface, and even tin-rich fine particles, commonly known as tin sweat, can be reduced by improving the calcination method and production process specifications. In liquid aluminum alloy profiles, tin is easy to produce hard and brittle reference material SnO2. Smelters should be sufficient to deammonia to prevent the reduction of mechanical properties of aluminum alloy profiles caused by reference material; It is not sensitive to ultra-soft gas and can weld and braze well. No spark when destructive, no magnetic tape, low temperature resistance, and especially high wear resistance.
