Tube Spacer 1 Inch Spacers Decorative Aluminum Hole Attached Spacer

Tube spacer is a piece of tubing that lets the entire bolt pass through. Since they cannot be tightened, they are usually round. External thread to fix the spacers. Lathed tube can be cut off and chamfer OD and ID on both ends of a tube in one chucking. The stationary tube is gripped by two chucks—one before the rotating cutoff head, one after. Ever Hardware provides custom-made fasteners 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. Aluminum 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. Aluminum 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. Aluminum 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 aluminum oxide forms when the bare metal is exposed to air, effectively preventing further oxidation, in a process termed passivation.
