The blocking method is suitable for the production of a variety of metals and their alloys, and its products are widely used, especially in the fields of construction, aviation, aerospace, transportation, communication and so on.
Among non-ferrous metal materials, the most widely used are aluminum and aluminum alloys, copper and copper alloys. This kind of metal material has good electrical conductivity, thermal conductivity, good corrosion resistance, almost no surface treatment can naturally form an antioxidant protective layer, the appearance is clean, bright, easy to process and assemble, the earth's crust is rich in storage and other advantages, and the application is very wide. Among them, an overview related to the production of laminate is given below.
First, building structural materials
Aluminum and aluminum alloy profiles are good structural materials and have been significantly used to replace steel and wood materials. It can be used to manufacture the curtain wall structure of buildings, doors, Windows, stair handrails, elevator compartments, rolling elevator articulated foot pedals, structural materials for mobile houses, etc.
The use of aluminum and aluminum alloy pressed products, with glass or other materials made of furniture, has also been quite common, durable, easy to clean.
Copper and copper alloy laminated products used as building materials (doors, Windows, handrails, hardware devices, etc.) more elegant sense. The use of laminated products for interior decoration is also unique. The number of copper and copper alloy pipes used for water supply and heating system of buildings increased significantly after being pressed and then stretched. The use of copper pipe construction is fast, and the service life is basically the same age as the building structure. In recent years, the copper water pipes used in urban buildings in developed countries have been close to 50% of the total water pipes. Copper water pipes are non-toxic and harmless, and are recognized as environmentally friendly materials in the international construction industry. Aluminum-coated water pipes and gas pipes are also widely recognized in the construction industry, but their service life is far less than that of copper pipes. Although the use of copper pipe one-time investment is large, but can be compensated from the maintenance cost savings, long service life.
The "Mir" space station built by the former Soviet Union (due to exceeding the expected life of the operation, has been artificially controlled in the atmosphere burned), the newly built International Space Station by the United States, Germany, Russia and other countries, aluminum and aluminum alloy extrusion profiles are the main structural materials of space stations. Of course, there are some engineering plastics, but most engineering plastics are also produced by the press block method.
