According to the manufacturing process, it is divided into cast zinc alloy and deformed zinc alloy. Commonly used cast zinc alloys are zinc-aluminum-copper-magnesium alloys, which have good casting process performance, and the cooling rate has little effect on mechanical properties.
They are mostly used in the manufacture of mechanical parts, toys, decorations, and household appliances. In order to improve the strength and hardness of the alloy, a small amount of alloying elements such as copper and magnesium are also added.
It has high strength and is easy to shape, and can replace some brass or duralumin to make precision forgings. The latter contains 0. Copper can increase alloy strength and impact toughness, and reduce plasticity. Zinc-copper alloy is suitable for making daily hardware products or replacing parts of brass.
In addition, there are zinc-titanium-based, zinc-lead-cadmium-iron-based deformed zinc alloys. The supply status of wrought zinc alloy is wire, plate, forging or extrusion, etc. DX51D is a galvanized sheet of bending and forming grade, the steel grade serial number is 51, with low carbon steel as the base material.
That is to say, a layer of zinc is plated on the hot-dip galvanizing. In general, N refers to the fingerprint-resistant coating on the surface. A refers to the A-level surface. C represents roll, coil, generally 1. Hot-dip galvanizing is coated with a layer of zinc. The substrate used in hot-dip galvanizing is cold-rolled, and the zinc plating on the cold-rolled sheet is called galvanizing.
Ordinary hot-dip galvanizing is 80 grams. For galvanized steel, only by fully understanding its various aspects, can we make better use of it, give full play to its maximum role, and serve us. The difference between the two is as follows:. DC51D substrate is DC01 cold rolled low carbon steel plate. Galvanized products are widely used in various fields such as industry, agriculture, animal husbandry and fishery, energy, transportation, chemical industry, light industry, household appliances, construction, communication, and national defense, etc.
The main uses are as follows:. Industry: all kinds of industrial pipes, air ducts, all kinds of corrosion-resistant parts, outdoor cabinet frame structure, etc. Construction industry: all kinds of industrial and commercial civil buildings, processing plants, airports, stadiums, mobile homes, etc.
Household appliances: Galvanized steel is mainly used in air conditioners, washing machines, refrigerators, microwave ovens, refrigerators, VCD machines, color TVs, water heaters, kitchen equipment, radio cassette recorders, video recorders, etc.
Light industry and commerce: Galvanized steel is mainly used to make cylinders, barrels, boxes, furnace tubes, billboards, traffic signs, armored cables, straps, containers, chimneys, etc.
Agriculture, animal husbandry, and fishery: galvanized steel is mainly used to make granaries, drying equipment, storage, and transportation containers, fishery wire ropes, nets, freezers, various corrosion-resistant frames for marine use, plastic greenhouse structures, agricultural tools, etc.
Transportation industry: the inner and outer panels of various vehicles, body brackets, other corrosion-resistant parts, highway guardrails, street light poles, highway isolation nets, isolation railings, various indicator signs, railways, ships, docks, and other places. Chemical industry: all kinds of corrosion-resistant pipes, conduits, containers for chemical products, corrosion-resistant parts of chemical equipment, etc.
Electricity power communication industry: various power transmission towers, TV transmission towers, relay towers, pager transmission towers, satellite ground relay towers, cable supports, etc. As the grade of DX51D galvanized steel sheet has strong anti-corrosion performance, it is currently widely used in construction, home appliances, vehicles and ships, container manufacturing, electromechanical industries, etc.
