Copper Coil from Austral Wright Metals

Austral Wright Metals is an Australian specialty metals supplier with national stockholding across stainless steel, aluminium, copper, brass, bronze and specialty alloys. The team supports industrial, architectural and electrical buyers with technical product guidance and reliable supply

The superior qualities of copper make it the ideal choice in a vast range of commercial, industrial and domestic applications.

To meet the exact specifications of our customers we stock and supply rolled products from the leading copper mills around the world. Not all copper is equal. The smelting process, and use of recycled copper, means careful control of impurities and oxygen are required to produce copper suitable for commercial purposes. The manufacturing steps also require exact control to achieve consistent and quality end products.

What is Copper Coil?

Copper coil is a flat, thin copper product used where corrosion resistance, malleability, electrical conductivity and thermal conductivity are required. In Australia, copper coil is commonly used for roofing, flashing, cladding, fabrication, decorative work and industrial manufacturing.

Copper Coil Sizes & Thicknesses

Item	Thickness range	Width range	Weight
Coil	0.55 to 0.9mm	1200mm	500kg
Pancake coils	2.5mm to 6.3mm	16mm to 40mm	25kg to 60kg

Buyers guide for specifying copper coil

Form	State required form, ie coil, pancake
Thickness	Specify required mm thickness based on strength, formability and application.
Width & Length	Confirm available stock sizes and whether custom cutting is required.
Grade	Select based on conductivity, weldability, fabrication and end-use environment.
Quantity	Provide project volume for quoting and availability checks.
Specification	Typically international standards like ASTM, EN and AS1567

Copper Coil benefits & properties

In addition to its well known traditional properties – electrical and thermal conductivity, malleability and resistance to corrosion – copper is far more versatile in combining with other metals to provide performance characteristics needed to satisfy today's increasingly complex demands.

Some of the most important properties that have lead to the wide use of copper today are:

it is an excellent electrical conductor, second only to that of silver. In 1913 copper was made a standard 100% conductivity, ie IACS (International Anneal Copper Standard).
Ductile - can be rolled into foil with a thickness of as little as 7 micron.
Good casting properties that facilitates the production of fine details.
Easy to join by solder or welding.
Resistant to most types of corrosion.
Ability to form alloys that have attractive colour and can be given a high polish.
More recently the excellent antimicrobial properties of copper have been realised.

Some of the benefits of copper are:

very good hot and cold workability
ability to form a natural patina in the atmosphere that aides corrosion protection
100% recyclable
as copper is a noble metal which means it's galvanic corrosion resistance with other metals is very good.

Copper Sheet vs Copper Plate vs Copper Coil

Product	Best For	Key Difference
Copper Sheet	Roofing, cladding, fabrication, electrical parts	Flat sheet format for general-purpose applications
Copper Plate	Heavier-duty industrial and structural uses	Thicker and more rigid than sheet
Copper Coil	Roll-forming, continuous processing and manufacturing	Supplied in coil form for production workflows

What Grades and Applications are used for copper coil products

Oxygen free copper (Cu-OF)

99.95% purity, not susceptible to hydrogen embrittlement at elevated temperatures. Used in electrical applications such are transformer generators and cabling.

Oxidised Copper (ETP)

99.9% purity with traces of cupric oxide. Not suitable for high temperature joining techniques. Used in electrical busbars, motor and transformer windings, electrical switches and connectors.

Deoxidised Copper (DHP)

Small addition of phosphorus is added to bind with oxygen to make this alloy suitable for welding. This addition reduces the electrical conductivity of the metal so is not used in electrical applications. Used in roofing, vessels, shower trays and architectural applications.

Copper Coil FAQs

What is copper coil used for?

Copper coil is used for roofing, flashing, cladding, electrical components, busbars, connectors, fabrication, decorative panels, heat transfer components and industrial manufacturing.

What thickness copper coil do I need?

The right copper coil thickness depends on the application. Thinner sheets are easier to form and cut, while thicker sheets provide more rigidity, strength and durability.

Can copper coil be custom cut?

Yes. Copper coil can often be supplied in standard sizes or custom-cut formats depending on stock availability and project requirements. Copper sheet can be cut using hand shears, guillotine, water jet or laser cutter.

Is copper coil suitable for roofing?

Yes. Copper coil is widely used for roofing, flashing, gutters, cladding and architectural features because it resists corrosion and develops a protective patina over time. The life span of copper for roofing can last over a hundred years.

Is copper coil good for electrical applications?

Yes. Copper sheet is highly suitable for electrical applications because copper has excellent electrical conductivity and is commonly used in busbars, terminals, switches, switchgear, electrical chasis and connectors. Visit Copper Busbar for details on our copper flat bar.

Can copper coil be soldered or brazed?

Yes. Copper coil can generally be soft-soldered, brazed or fabricated, although suitability depends on the copper grade, thickness and project requirements.

Where can I buy copper coil in Australia?

Austral Wright Metals supplies copper coil across 4 major Australian cities for fast delivery, with strong stockholding, technical support and delivery options for industrial, electrical, architectural and fabrication customers.
