Brass Suppliers and Machining in Huntington, WV: Valve, Fitting & Precision Parts

C260 cartridge brass (70% Cu, 30% Zn) is the alloy of choice for components produced by deep drawing, stamping, spinning, and forming operations where ductility and formability take priority over machinability. Its elongation of 45-68% in the annealed condition allows drawing depth ratios of 2.5:1 or greater without intermediate annealing — enabling single-hit production of deep shells, cups, and tubes that would crack in C360 or stiffer alloys. The name 'cartridge brass' reflects its original application in ammunition case manufacture, and the same properties that make it ideal for that application — consistent forming behavior, uniform grain structure, and spring-back predictability — make it the standard for Huntington-area shops producing stamped electrical terminals, connector shells, relay springs, and drawn tubular fittings. C260 sheet (0.010" to 0.125") and strip are the primary stock forms. Cold-drawn C260 tube in OD sizes from 1/4" to 2" is used for heat-exchanger tubes, condensate return lines, and fluid-handling assemblies in Huntington's industrial facilities. The alloy's corrosion resistance is good in neutral water and many organic solvents but — like all brass — C260 is susceptible to dezincification in warm, slightly acidic, or oxygen-rich water, and to stress-corrosion cracking (season cracking) in ammonia-containing environments. Components to be used in moist industrial environments containing even trace ammonia should be stress-relieved at 475-500°F after forming to eliminate residual forming stresses that drive stress-corrosion cracking.

Naval brass (C464, C465) adds 0.75-1.0% tin to the 60% copper, 40% zinc base of yellow brass. The tin addition dramatically improves resistance to dezincification — the selective leaching of zinc from the brass matrix that leaves behind a porous, weak copper sponge. Dezincification is accelerated in warm water above 60°F, in water with elevated chloride or dissolved CO2, and in stagnant or low-flow conditions. Ohio River industrial facilities using brass fittings in cooling water circuits at temperatures above 80°F have historically experienced dezincification failures in standard C360 and C270 fittings within 5-10 years; the same service in naval brass runs 25+ years without failure. Huntington energy facilities, chemical plants, and marine equipment serving the Ohio River barge industry specify naval brass for gate valves, globe valves, ball valves, pipe nipples, and pump impellers in all water-service applications. ASTM B21 covers naval brass rod and bar; B171 covers naval brass plate for heat-exchanger tube sheets and flanges. Naval brass machines at approximately 30% of B1112 standard — slower than C360 but still well ahead of stainless or nickel alloys — and it can be hot-forged and hot-extruded for near-net-shape valve body production, reducing machining allowance and cycle time on complex geometries. For buyers evaluating dezincification-resistant brass versus other corrosion-resistant alloys for water service, naval brass occupies the cost-performance sweet spot between standard C360 (susceptible to dezincification, lower cost) and copper-nickel C706 or bronze C932 (higher dezincification resistance, higher cost). For Ohio River cooling-water service at temperatures up to 150°F with moderate chloride levels, naval brass is typically the optimal specification.

C360 and C260 are readily stocked by regional metals distributors and industrial supply houses in Huntington, with same-day or next-day availability for round bar, hex bar, and sheet in standard dimensions. Naval brass (C464) is a less common stock item — regional distributors may carry limited inventory, and lead times of 3-7 days from Pittsburgh or Cincinnati distributors are typical for non-standard sizes. Brass procurement quality requirements center on two issues: composition verification and lead-content certification for regulated applications. For standard industrial work, an ASTM or UNS certification from the distributor confirming the alloy grade is sufficient. For components entering water-system, medical, or food-contact applications, NSF 61 listing of the fittings or NSF 372 'lead-free' certification of the base metal is required by code in West Virginia plumbing regulations (adopted IPC and IRC). For aerospace or defense applications where AS9100 quality system requirements apply, full chemical and mechanical MTRs traceable to a domestic mill are required, and some prime contractors further require Country of Origin documentation confirming the material is not of Chinese origin under DFARS 252.225-7014 restrictions on specialty metals. Brass chips and scrap from CNC machining are high-value recycling streams: clean C360 turnings recover at $1.20-$2.00/lb at current copper prices. Shops should segregate brass chips from steel, aluminum, and other metals scrap — mixed metal contamination reduces recovery value substantially. Several regional scrap buyers in the Huntington-Charleston area accept segregated brass and copper scrap with competitive pricing.
