How to Choose Aluminum Strip for Armoured Cable

2026-04-29

Aluminum strip is widely used in armoured cable manufacturing as a protective armoring or wrapping material. It provides lightweight protection, corrosion resistance and good processing performance for cable production.

For cable manufacturers, choosing the right aluminum strip is important. The material must match cable design, production equipment and performance requirements. If the aluminum strip has unstable width, poor surface quality, unsuitable temper or bad coil condition, it may affect cable production efficiency and final cable quality.

This article explains how to choose aluminum strip for armoured cable applications.

What Is Aluminum Strip for Armoured Cable?

Aluminum strip for armoured cable is a flat aluminum material used in cable armoring, wrapping or protection layers. It is usually supplied in coil form and processed continuously during cable production.

It may also be called:

• Aluminum strip for armoured cable

• Aluminum strip for armored cable

• Cable armoring aluminum strip

• Aluminum tape for armoured cable

• Aluminum strip for cable wrapping

Both “armoured” and “armored” are used in the market. “Armoured” is common in British English, while “armored” is common in American English.

Why Aluminum Strip Is Used in Armoured Cable

Aluminum strip is used in cable armoring because it offers several advantages.

1. Lightweight Protection

Aluminum is lighter than many other metal materials. It can provide protection while helping reduce cable weight.

2. Corrosion Resistance

Aluminum has good corrosion resistance, making it suitable for cable protection applications.

3. Good Formability

Aluminum strip can be wrapped or formed during cable production. Proper temper selection helps improve processing performance.

4. Cost Efficiency

Aluminum is generally cost-effective and suitable for large-scale cable manufacturing.

5. Customizable Specifications

Aluminum strip can be customized by alloy, temper, thickness, width and coil size according to cable production requirements.

Common Applications

Aluminum strip can be used in different cable types, including:

• Armoured power cable

• Medium voltage cable

• Low voltage cable

• Control cable

• Industrial cable

• Cable wrapping layer

• Cable protection layer

The specific requirement depends on cable structure and production process.

Choose the Right Aluminum Alloy

Different aluminum alloys offer different mechanical and processing properties.

Common aluminum alloys for cable applications may include:

The final alloy should be selected according to cable design, mechanical performance requirements and customer standards.

Select the Proper Temper

Temper affects hardness, strength and forming ability.

Common tempers may include:

• O

• H12

• H14

• H16

• H18

• Customized temper

For cable armoring, the strip should have suitable strength and formability. If the material is too hard, it may be difficult to process. If it is too soft, it may not provide enough mechanical protection.

The right temper should match the customer's cable production equipment and cable performance requirements.

Confirm Thickness and Width

Thickness and width are key specifications for cable aluminum strip.

When selecting thickness and width, customers should consider:

• Cable diameter

• Armoring structure

• Wrapping method

• Production speed

• Required protection performance

• Equipment compatibility

Stable width tolerance is especially important for continuous cable production. If width variation is too large, it may cause wrapping problems or production instability.

Thickness accuracy is also important because it affects mechanical protection and material consumption.

Surface Quality Requirements

Surface quality can affect both production efficiency and final cable quality.

Good aluminum strip for armoured cable should have:

• Smooth surface

• Clean surface

• No serious scratches

• No heavy stains

• No oxidation problems

• No serious dents or marks

Surface defects may affect cable appearance, wrapping stability or downstream processing.

For export orders, surface protection during packaging and transportation is also important.

Mechanical Performance Requirements

Cable armoring aluminum strip should have suitable mechanical properties.

Important factors include:

• Tensile strength

• Elongation

• Hardness

• Formability

• Flexibility

• Edge condition

Different cable structures may require different mechanical performance. Customers should confirm their technical requirements before placing an order.

Edge Quality and Coil Condition

Edge quality is important for continuous cable production.

Poor edge condition may cause:

• Processing difficulty

• Equipment wear

• Strip breakage

• Poor wrapping quality

• Surface or cable damage

Good coil condition is also important. The coil should be stable, properly wound and easy to feed into cable production equipment.

Important coil requirements include:

• Stable coil winding

• No serious deformation

• Good edge alignment

• Proper coil inner diameter

• Safe packaging

• Easy handling

Packaging for Export Shipment

Aluminum strip for cable applications is often shipped internationally. Proper packaging helps protect the material during transportation.

Good export packaging should prevent:

• Moisture damage

• Surface scratches

• Coil deformation

• Edge damage

• Transport movement

Common packaging methods include:

• Moisture-proof wrapping

• Plastic film protection

• Wooden pallet

• Wooden case

• Edge protection

• Strong coil fixing

For B2B buyers, packaging quality is an important part of supplier evaluation.

How to Choose a Reliable Supplier

A reliable aluminum strip supplier for armoured cable should provide:

• Suitable alloy and temper options

• Custom thickness and width

• Stable width tolerance

• Good surface quality

• Good coil condition

• Export packaging experience

• Technical communication

• Quality inspection support

• On-time delivery

Cable manufacturers should provide clear technical specifications and application information to help the supplier recommend suitable material.

Information to Provide When Requesting a Quote

To get an accurate quotation, customers should provide:

• Aluminum alloy

• Temper

• Thickness

• Width

• Coil inner diameter

• Coil weight if required

• Surface requirement

• Edge requirement

• Quantity

• Application

• Packaging requirement

• Destination port or country

The more complete the information, the faster the supplier can provide a suitable quotation.

Choosing aluminum strip for armoured cable requires attention to alloy, temper, thickness, width, surface quality, mechanical properties, edge condition, coil condition and packaging.

A suitable aluminum strip can help improve cable production efficiency, reduce material problems and support stable cable quality.

For cable manufacturers, working with a supplier who understands cable armoring applications is very important.
