n: a substance with metallic properties that comprises two or more elements in solid solution. See ferrous alloy, nonferrous alloy.

n: The drill pipe made by alloy of titanium and aluminium. It is lighter than the isometric drill pipe made by steel. It improves the drilling depth of rig, has good fatigue resistence and can absorb shake when connected above the drill collar.

n: an alloy of copper and aluminum that may also include iron, manganese, nickel, or zinc. aluminum cable steel-reinforced

n: metal alloy, either tin-based or lead-based, used primarily in friction bearings.

a soft metal alloy used in some seals and bearings.

n: The casing float in which is installed by check valve. There are two kinds of ball float collar: cement lining and aluminum alloy lining.

a slip for high alloy (hard) casing.

a low alloy steel, containing a mass fraction maximum of 2% carbon, 1.65% manganese and residual quantities of other materials. Common in pipe manufacture.

heat-treating process where carbon is introduced into a solid iron alloy by heating above transformation temperature range while in contact with a carbonaceous material (solid, liquid, or gas form of carbon). Usually quenched to produce a hardened outer s

n: A method of ferroalloy hardening. The purpose is hardening its surface to improve abrasiveness.

n: The nipple of alloy steel whose bottom presents cone. There are center bore and several pieces of fraises with kerf in it. Mainly used for chipping fracture of casing.
