Metal Rod and Bar Stock

Metal rod and bar stock are metals and alloys in the form of round bars or rod, square bars, rectangular or flat bars, hexagons, and other bar stock shapes. These shapes are also available in billet form and typically included a cross-section based on the shape of the rod or bar stock. Reinforcing bars may also be included; these bars are included to strengthen or internally support concrete and masonry structures. Other metal rod and bar stock forms include coil stock and hollow tube stock.

Ferrous or nonferrous metal rods and bar stock are available. Ferrous metals and alloys are iron-based; common ferrous metals and alloys used for rods and bar stock include carbon steel, alloy steel, stainless steel, tool steel, cast iron, and cast steel. Carbon steels (UNS G) are used to make metal rod and bar stock. Plain carbon steels are based on iron, carbon, and smaller varying amounts of other alloying elements. Alloy steel (UNS G) are used in a wide variety of applications in almost every industrial segment. These steels can be easily fabricated by machining, forming, casting, and welding.

Tool steel, cast iron, and cast steel are also ferrous metals used for metal rod and bar stock. Tool steel (UNS T) is iron and carbon based with high levels of hardening and property alloying elements. Tool steel are exhibit excellent wear resistance but are difficult to fabricate in their hardened form. Cast iron (UNS F) is another ferrous metal that is used in metal rod and bar stock. This metal is an iron alloy that contains high amounts of carbon. Cast steel (UNS J) is an alloy grade is that is produce by pouring molten iron into a mold. Other types of ferrous metals are also used for metal rods and bar stock.

Nonferrous metal rod and bar stock is also available. Common types of nonferrous metal rod and bar stock include aluminum, cobalt, copper, nickel, refractory, and titanium. Aluminum and aluminum alloys (UNS A) is a lightweight metal that exhibits good corrosion resistance, ductility, and strength. This metal is easily fabricated by forming, machining, or welding. Cobalt metal rods and bar stock have high strength and toughness, excellent corrosion and oxidation resistance, and high temperature strength. Copper, brass, or bronze alloys (UNS M) maintain electrical and thermal conductivity, good corrosion resistance, ductility, and strength. Although pure copper is difficult to weld, it is a useful alloying element in aluminum alloys and powder metal-based iron alloys.

Metal rod and bar stock can also be made from nickel and titanium. Nickel and nickel alloys (UNS N) are nonferrous metal rods and bar stock that has high strength and toughness, excellent corrosion resistance, and superior elevated temperature properties. Titanium or titanium metal rods and bar stock are used in many applications due to their corrosion resistance, good fatigue properties, and high strength-to-weight ratio.  Other types of metals and alloys are also used in metal rods and bar stock.
