Copper Wires Specifications

Chemical Composition for Copper Wires supplied by Ritvik Metal Impex
Grade	UNS	Cu (min)	P	O	Conductivity	Typical use
ETP — Electrolytic Tough Pitch	C11000	99.90%	—	0.02–0.05	≈ 101% IACS	Busbars, strips, wire, conductors
DHP — Deoxidised High Phosphorus	C12200	99.90%	0.015–0.040	Nil	≈ 85% IACS	Water tube, ACR tube, heat exchangers
DLP — Deoxidised Low Phosphorus	C12000	99.90%	0.004–0.012	Nil	≈ 98% IACS	Brazed assemblies needing conductivity
OFE — Oxygen Free Electronic	C10100	99.99%	—	0.0005 max	≈ 101% IACS	Vacuum, semiconductor, high reliability
OF — Oxygen Free	C10200	99.95%	—	0.001 max	≈ 101% IACS	High-purity electrical and brazed work

Note: The grade is chosen by whether the product will be brazed or will carry current. Deoxidised grades braze safely; ETP maximises conductivity.

Mechanical Properties by Temper for Copper Wires supplied by Ritvik Metal Impex
Temper	Designation	Tensile Strength	Elongation	Supplied as	Typical use
Annealed / soft	O60	205–260 MPa	≥ 40%	Coils	ACR line sets, instrument lines, buried runs
Half hard	H55	250–310 MPa	≈ 25%	Straight lengths	Formed work needing some rigidity
Hard drawn	H58	≥ 310 MPa	≈ 8%	Straight lengths	Exposed risers, busbar stock

Note: Temper governs both formability and allowable working pressure. Annealed coil bends by hand; hard drawn is supplied in rigid straight lengths.

Size Range & Supply Condition for Copper Wires supplied by Ritvik Metal Impex
Parameter	Range
Bare wire diameter	0.09 mm to 12 mm
Enamelled wire diameter	0.05 mm to 5 mm (SWG, AWG or IEC 60317 metric sizes)
Thermal class — enamel	155 (F), 180 (H), 200, 220
Grade of build	Grade 1, Grade 2, Grade 3
Enamel type	Polyester, polyesterimide, polyamide-imide overcoat, self-bonding, solderable
Packing	Spools, reels, coils and drums
Standards	IEC 60317, IS 13730, NEMA MW 1000, JIS C 3202

Product Standards by Application for Copper Wires supplied by Ritvik Metal Impex
Standard	Covers	Sizing convention	Typical application
ASTM B88	Seamless copper water tube	Nominal size (OD = nominal + 1/8")	Potable water, plumbing, general fluid
ASTM B280	Seamless ACR tube	Actual outside diameter	HVAC, refrigeration field service
ASTM B111	Condenser tube & ferrule stock	Actual OD and wall gauge	Condensers, heat exchangers, evaporators
ASTM B68	Bright annealed seamless tube	Actual OD	Instrument and hydraulic lines
ASTM B152	Copper sheet, strip, plate & bar	Thickness and width	Busbars, strips, pressed components
IEC 60317	Enamelled winding wire	Conductor diameter	Motor, transformer and coil windings

Note: The three copper tube standards are not interchangeable — B280 ACR tube is cleaned, dehydrated and capped at the mill, and is sized by actual outside diameter.

Industrial Copper Wires: Grades, Specifications & Applications

Copper wire is the foundation of modern electrical infrastructure. From power transmission to precision winding, the quality and consistency of copper wire directly impacts the performance and reliability of electrical systems.

Copper Wire Grades

ETP (Electrolytic Tough Pitch) Copper — standard grade with minimum 99.9% purity and conductivity ≥100% IACS. OFHC (Oxygen Free High Conductivity) — for high vacuum, cryogenic, and high-frequency applications. DHP Copper — for general industrial and heat exchanger applications.

Wire Gauges & Sizes

Available from 0.02mm (42 SWG) to 8mm diameter. Standard wire gauges: SWG (Standard Wire Gauge), AWG (American Wire Gauge), and metric mm sizes. Supplied in coils, spools, or drums depending on size.

Temper Conditions

Soft/Annealed — maximum flexibility, used for winding and flexible cables. Hard Drawn — maximum tensile strength for overhead conductors. Half Hard — intermediate properties for bus bars and connectors. Bright annealed finish standard; tinned copper available for soldering applications.

Applications

Winding wire for motors and transformers, flexible cables, overhead transmission conductors, earthing and grounding systems, PCB manufacturing, and communication cables.
