Aluminium is a relatively soft, durable, lightweight, ductileand malleable metalwith appearance ranging from silvery to dull gray, depending on the surfaceroughness. It is nonmagnetic and does not easily ignite. A fresh film ofaluminium serves as a good reflector (approximately 92%) of visible lightand an excellent reflector (as much as 98%) of medium and far infraredradiation. The yield strength of pure aluminium is 7–11 MPa,while aluminium alloys have yield strengths ranging from200 MPa to 600 MPa. Aluminium has about one-third the densityand stiffness of steel. It is easily machined,cast, drawn and extruded.

Aluminium alloys (or aluminum alloys; see spellingdifferences) are alloysin which aluminium(Al) is the predominant metal. The typical alloying elements are copper, magnesium,manganese,silicon,tin and zinc. There are twoprincipal classifications, namely casting alloys and wrought alloys, both of which are furthersubdivided into the categories heat-treatableand non-heat-treatable. About 85% of aluminium is used for wrought products,for example rolled plate, foils and extrusions.Cast aluminium alloys yield cost-effective products due to the low meltingpoint, although they generally have lower tensile strengthsthan wrought alloys. The most important cast aluminium alloy system is Al–Si,where the high levels of silicon (4.0–13%) contribute to give good castingcharacteristics. Aluminium alloys are widely used in engineering structures andcomponents where light weight or corrosion resistance is required

Q: Are aluminum coils compatible with different joining methods?: Yes, aluminum coils are compatible with different joining methods. Aluminum is a highly versatile metal that can be joined using various techniques such as welding, brazing, soldering, and mechanical fastening. The choice of joining method depends on the specific application and the desired properties of the joint. Welding is commonly used to join aluminum coils as it provides a strong and durable bond. Several welding techniques like MIG (Metal Inert Gas), TIG (Tungsten Inert Gas), and resistance welding can be used depending on the thickness and type of aluminum alloy being joined. Brazing is another effective method for joining aluminum coils. It involves the use of a filler material that has a lower melting point than the base metal, which is heated to create a strong joint. Brazing is commonly used when the aluminum coils need to be joined to other dissimilar metals. Soldering is suitable for joining thin aluminum coils or when a lower temperature method is required. It involves melting a low-temperature alloy (solder) to join the coils together. Soldering is commonly used in electronics and plumbing applications. Mechanical fastening methods such as bolts, screws, rivets, or clips can also be used to join aluminum coils.
