Usage

Everyone knows that copper is second only to silver in electrical and thermal conductivity. It has good corrosion resistance and can be used in the chemical industry. It is widely used in the production of electrical and thermal conductive equipment. Copper is usually made into copper and copper strips. What are the more common uses of copper plates in daily life?

1. The use of copper plate is much wider than pure iron. Every year, 50% of the copper is purified and purified into pure copper for use in the electrical industry.
2. Atmospheric copper, seawater and some non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solutions and various organic acids (acetic acid, citric acid) have good corrosion resistance and are used in the chemical industry. In addition, copper has good weldability and can be processed into various semi-finished products and finished products through cold processing and thermoplastic processing.
3. Copper plate has unique excellent performance. It is an ideal alternative material for circuit breakers, contact plates and conductive parts of low-voltage air switches in the electrical industry. The metallographic structure of the product is fine grain refinement, the tensile strength of the pure copper plate is increased by 10.4%, the hardness is increased by 3%, the electrical conductivity of the copper plate is increased by 4.5%, 2.8%, and the wear resistance is significantly improved compared with the imported alloy plate.

4. Excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance. It is mainly used in the manufacture of electrical equipment such as generators, busbars, cables, switchgear, transformers, and flat plate collectors for other heat-conducting equipment such as heat exchangers, pipes, and solar heating equipment.
5. Suitable for all kinds of advanced hydraulic construction foundation water stop belt, dam body water stop belt, dam top water stop belt, corridor water stop belt, dam body hole water stop belt, plant water stop belt, horizontal joint water stop belt, etc. Overflow surface, etc., is the most ideal product to prevent omission.

Of all the metal materials used in construction, copper has the best elongation properties and has great advantages in adapting to the shape of the building. Copper sheet is not limited by processing temperature, and is not brittle at low temperatures, and can be hot-fused by blowing oxygen at a high melting point. Fireproof, non-combustible material.
