Aluminium alloy grade including 1xxx, 2xxx, 3xxx, 4xxx, 5xxx, 6xxx, 7xxx, 8xxx. But the most common is 1050, 3003, 6061 and 5251 aluminum coil. Thickness from 0.045-80mm, width from 60-2650mm. Common widths of aluminum coil is 800mm,1000mm, 1250mm,1450mm and 1500mm.

    Multiple industries rely on aluminium coils for a variety of applications, such as automotive, construction, heat transfer, pharmaceutical, electrical, and food industry. Compared to other materials, aluminum is a far superior material in many instances. Aluminum coil can be supplied with standard mill finish, or it can be brushed, checkered, color coated, satin-finished and anodized. Aluminium sheet or aluminium foil can be cut into coils as per client’s requirements.

  • Aluminium Strip

    Aluminum sheet & foil in the form of rolls with a thickness > 0.2mm, a width 20mm to 100mm is generally called aluminium strip. The common name for aluminium strip that is produced in small strip widths is usually split strip. Aluminium sheets are cut into a required by slitting tooling, the raw material of aluminum strip is pure aluminium or aluminum alloy hot rolled cast-rolling aluminum coil and hot-rolled coil. Through a cold-rolled machine to form different thickness and width of the rolling sheet and aluminum coil, and then the vertical cutting and slitting machine for different width of the strip. And the thickness<0.2mm, we call it aluminum foil strip or aluminum foil coil.

  • Aluminium foil

    Aluminium foil is aluminium prepared in thin metal leaves with a thickness of less than 0.2mm (7.9 mils); thinner gauges down to 4 micrometers are also commonly used. Standard household foil is typically 0.016 mm (0.63 mils) thick, and heavy-duty household foil is typically 0.024 mm (0.94 mils). And the air conditioner foil can be thinner than 0.0047mm, and some food foil thinner than 0.002mm. The foil is pliable and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated with other materials such as plastics or paper to make them stronger and more useful. It’s used industrially for a variety of purposes, including packing, insulation and transportation. At home, people use aluminum foil for food storage, to cover baking surfaces and to wrap foods, such as meats, to prevent them from losing moisture while cooking.

  • Copper Coils

    It may seem that a copper coil is a simple piece of coiled wire that can be wound and put to use. As with any form of industrial product, copper coils have to be precisely engineered to fit an application. The winding process has to be completed with precision to ensure the proper distance between the wires and the diameter of the opening.

    Each product that uses copper coils requires that a certain number of turns be made to provide the correct amount of resistance. Inaccurate calculations can lead to inefficiency and possible failure of the coil or device. For this reason, the engineers at Metal Associates guarantee that they have closely examined the specification of an application such that the diameter, spacing, wire thickness, and number of turns exactly matches the design of the product where the copper coil will be used.

  • Copper Sheet

    Copper sheet is a very workable and malleable form of metal, high in electrical and thermal conductivity, and provides excellent corrosion resistance. A beautiful and versatile metal, copper has been utilized for thousands of years. Historically, it served as a favorite choice in making tools, vessels, and sculptures. Copper is also known for its beautiful patinas. When exposed, unsealed, to an outdoor environment, copper begins to oxidize. This exposure creates beautiful color variations in the form of a patina. The coloring of the patina will change and develop character over time while serving to protect the metal from deterioration. People will also create a patina quickly with the use of chemical mixtures that speed the process up and allow a patina to develop without outdoor exposure. Copper sheets can also be hammered, tooled, or embossed for added texture and decorative or functional appeal and come in many thicknesses from very thin copper foil to thick copper plate. It also comes in many alloys that blend other metals with copper. At Grand Copper, we sell pure copper -C110 (other alloys and tempers available upon request). This high purity provides the premium quality needed for projects and applications in a wide range of industries and uses. We take pride in providing the best material. Our high-quality, affordable material and friendly, first-rate customer service have made us a leader in the industry for over a decade.

Moreover, these SS Sheets & Plates are highly demanded in various industries like chemical & food processing, heat exchangers, fresh & saltwater marine environments, automobiles and more.

  • Stainless Steel Strips

    tainless steel is the name given to a group of corrosion resistant and high temperature steels. Their remarkable resistance to corrosion is due to a chromium-rich oxide film which forms on the surface. When ordinary carbon steel is exposed to rain water, for example, it corrodes forming a brown iron oxide, commonly called rust, on the surface. This is not protective and eventually the entire piece of steel will corrode and be converted to rust. But when enough chromium (more than about 10%) is added to ordinary steel, the oxide on the surface is transformed – it is very thin, virtually invisible and protective in a wide range of corrosive media. This is what we call stainless steel and there are several different types, and many different grades.

    The manufacture of quality stainless steel, from heat to heat and year to year, demands precise control of raw material ingredients and melting practices. Exact quantities of presorted scrap and alloying elements are delivered to the mills’ melting furnaces so that the heats or lots will be within specified composition ranges. Those composition ranges typically include a group of chemical elements for each grade of stainless steel.

  • Stainless Steel Coil

    Stainless steel 304/304L coils and stainless steel 316/316L coils, along with duplex stainless steel coils offer good corrosion resistance to many chemical environments as well as marine and industrial exposures.

  • Titanium coils

    Because of the poor thermal conductivity of pure titanium, the emulsion with good lubrication effect and excellent cooling performance is required in the rolling process, and the rolling speed should not be too fast, in order to prevent the high temperature of pure titanium and cause the phenomenon of “sticking roller”, and “sticking roller” resulting in rough surface of titanium and poor quality. The residual water and oil on the surface of the titanium strip decompose during the annealing process, which affects the partial pressure of oxygen in the furnace and causes the decomposition reaction to go in the opposite direction, forming oxidation on the surface of the titanium strip and affecting the annealing quality. Because titanium strip annealing before full degreasing cleaning and drying plate surface. The degreasing speed of titanium strip is generally 20m/min, and the speed is adjusted according to the surface quality of the titanium strip after degreasing. Straightening is to ensure the flatness of the product plate.
