Cap Nut Aluminum Custom Made Decorative Printer Kit Adjusting Flat
The cap nut is a nut that has a flat top to cover the threads. This is to prevent contact with the external thread to protect the threads or protect other things the threads would rub against. In addition, the head gives a more finished appearance. It is usually made of aluminum, brass, steel, stainless steel (low carbon content) or nylon. It can also be chrome plated and given a mirror finish. Ever Hardware provides the custom-made cap nut and customizable packaging.
Aluminum is a relatively soft, durable, lightweight, ductile, and malleable metal with appearance ranging from silvery to dull gray, depending on the surface roughness. It is nonmagnetic and does not easily ignite. 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. The yield strength of pure aluminum is 7–11 Mpa, while aluminum alloys have yield strengths ranging from 200 Mpa to 600 Mpa. Aluminium has about one-third the density and stiffness of steel. It is easily machined, cast, drawn and extruded.
Aluminum atoms are arranged in a face-centered cubic (fcc) structure. Aluminium has a stacking fault energy of approximately 200 mJ/m2.
Aluminum 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. 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).
Corrosion 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. The strongest aluminium alloys are less corrosion resistant due to galvanic reactions with alloyed copper. This corrosion resistance is greatly reduced by aqueous salts, particularly in the presence of dissimilar metals.
