It is common knowledge that metals can corrode. Affected by the environment, destructive damage is caused by chemical or electrochemical reactions. It can be said that almost all metal products will have some forms of corrosion in a certain environment, and copper bushings are also metal products. Naturally, they cannot prevent metal corrosion. The corrosion phenomenon is also significantly different when the environment and time of use are different. It also has a certain relationship with the material. Iron is the most susceptible to corrosion, while bronze bushings are slightly better. Tin bronze bushings are the most corrosion-resistant and can work in acidic and alkaline environments.
There are many polluting industries such as steel, petrochemicals, and thermal power generation. In addition, the number of cars has increased significantly in recent years, and a large amount of exhaust gas has been emitted, filling the air with corrosive sulfide and nitride gases and particles, which are the main causes of corrosion of metal castings. As environmental pollution intensifies, the severity of metal corrosion such as copper bushings, copper nuts and screws, bolts, structural steel and pipelines may exceed the estimated value, which obviously increases the burden and economic cost of production enterprises at different levels.
