![]() ![]() This corrosion resistance is greatly reduced by aqueous salts, particularly in the presence of dissimilar metals. ![]() The strongest aluminium alloys are less corrosion resistant due to galvanic reactions with alloyed copper. Aluminium is capable of superconductivity, with a superconducting critical temperature of 1.2 kelvin and a critical magnetic field of about 100 gausses (10 millie teslas).Ĭorrosion resistance can be excellent because a thin surface layer of aluminium oxide forms when the bare metal is exposed to air, effectively preventing further oxidation, in a process termed passivation. Aluminium has a stacking fault energy of approximately 200 mJ/m2.Īluminum is a good thermal and electrical conductor, having 59% the conductivity of copper, both thermal and electrical while having only 30% of copper’s density. It is easily machined, cast, drawn, and extruded.Īluminum atoms are arranged in a face-centered cubic (fcc) structure. Aluminium has about one-third the density and stiffness of steel. The yield strength of pure aluminum is 7–11 Mpa, while aluminum alloys have yield strengths ranging from 200 Mpa to 600 Mpa. A fresh film of aluminum serves as a good reflector (approximately 92%) of visible light and an excellent reflector (as much as 98%) of medium and far-infrared radiation. It is nonmagnetic and does not easily ignite. Ever Hardware provides custom-made aluminum dowel pins and customizable packaging.Īluminum is a relatively soft, durable, lightweight, ductile, and malleable metal with appearance ranging from silvery to dull gray, depending on the surface roughness. Our dowel pins all have a non-abrasive finish so they last as long as possible. These pins are common in the automotive and aerospace industries as well as in furniture making. Standard tolerances for our dowel pins are +.0001 / +.0003, unless specified as oversize. The aluminum dowel pins inserted into receiving holes, the pins hold together parts of an assembly with friction. ![]()
